Than dilute polyurethane varnish. Solvent for acrylic paints, varnish and glue - Get acquainted with the rules of choice

Protect the surface from various mechanical, chemical or atmospheric influences will help polyurethane paint. It is noticeably different from other analogues, both technical and operational qualities.

What is it so good? In the article, we will try to answer this question, consider views, differences, characteristics and applications polyurethane paints.

Decorative coating created with polyurethane paint

The unique qualities of this coating allow it an order of magnitude higher than others. paintwork materials.

The distinctive features of the paints are:

Polyurethane-based paint for a long time serves where ordinary paint coatings Quickly come into disrepair.

Types of colors

In terms of composition, polyurethane paints are divided into two types:

1. Single-component - immediately having all the necessary substances (diluents, hardeners, sequivans, etc.).
2. Two-component - before working, requiring mixing of two components from individual containers.

Manufacturers offer several types of paint, let's deal with what they differ from each other.

Polyurethane paint on organic solvents

Speaking simple language, this is normal paintPolyurethane modified.

It refers to the type of one-component paints and consists of several components:

• Polyurethane.
• Solvent (toluene, xylene).
• Pigment pigment.

Clarification or polymerization occurs under the influence of atmospheric moisture, which reacts with the binding components.

Important! The dry air in the room does not contribute to the setting of the composition, so the surface painted with polyurethane surface can not be dried by hot air. Simply put, the higher the humidity in the room, the faster he dried up, and vice versa.

After applying to the surface of the paint, one-component polyurethane gains strength after 48 hours. The coating acquires complete waterproof, special wear resistance, resistance to aggressive medium.

Water-dispersion polyurethane paint is great for coloring of plinths and walls.

This is a single-component paint in which ordinary water is used instead of solvent. It does not have a poisonous smell and completely harmless when painting.

The components of the mixture are evenly distributed in aquatic environment and form a steady dispersion. When evaporation of water, they gradually get closer, and then stick through in contact. As a result, we get a thin, durable film that has simultaneously decorative and protective properties.

Acquire it mainly for painting walls indoors with high humidity (cm. ). Paint for polyurethane stucco or plinths can also be water dispersive, as it has special elasticity and does not crack when the decorative details are bent.

Important! Since the paint in the composition has water, it is capable of freezing at low temperatures. After defrosting, the technical indicators are noticeably reduced.

Alkudo-Uretteen paint

The composition of this single-component paint includes the following components:

• Alkudine urethane varnish (serves for film formation).
• Syckens for rapid drying.
• Diluents.
• Pigments.
• Other target additives.

With the help of polyurethane enamel, you can create decorative and protective films with various textures and degrees of gloss. Apply it for both internal and outdoor work. For example, paint polyurethane for floors based on alkyd resins can cover both the floor in the garage and the paths in the yard.

The paint is resistant to temperature drops in the range from -60 to +60 degrees, no moisture is afraid, has excellent abrasion resistance, it is easy to apply a roller, brush or sprayer. Thanks to the sequivat, the paint will quickly dry (1.5-2 hours), when used by metal, serves as an excellent anti-corrosion agent.

Two-component paint polyurethane

It is produced and enters the sale in two tanks - separately containing resin and hardener.

The advantages of this separation are as follows:

• Possibility of cooking necessary number The solution "at once", while the residue does not lose its qualities with further storage.
• Curing and polymerization of paint occur without humidity.
• The coating is obtained more durable and wear-resistant than when using single-component compositions.

Two-component polyurethane paint is used for surfaces particularly susceptible to negative effects. It is resistant to soluble acids, alkalis, oil, various types of fuel, not afraid of marine and flowing water, Wastewater.

Mixing components with their own hands are produced in a separate container with a construction mixer to a complete homogeneity of the composition. The prepared mixture has a small lifespan (no more than 6 hours), so the flow must be calculated in advance, otherwise the residue will have to throw out.

The strength and durability of the coating directly depends on the implementation of the recommendations for mixing, which provides the manufacturer's instruction attached to the paint. In addition, it denotes the number of possible layers, the form and volume of the solvent, the conditions of application.

Comparative table of distinctive features of paints

Let's summarize the main distinctive properties different types mixtures and offer to see comparative table Pluses and minuses of polyurethane paints:

Important! Not depending on the type and type of polyurethane enamel on a polyurethane basis, only applied on the prepared surface, which should be cleaned from dirt, sucked, and if necessary, is projected. It depends on the provision of good adhesion and obtaining high-quality coverage. Soil is recommended to purchase precisely for the selected paint and from the same manufacturers.

As mentioned above, all polyurethane-based polyurethane paints perform not only decorative, but also protective functions. For example, polyurethane paint for metal protects structures from corrosion, some species when contact with open fire begins to foam, which delays the deformation of the metal to 1.5 hours.

The coating of porous surfaces (concrete, wood and other) is completely isolating materials from moisture penetration, and also protects them from the appearance of fungus, mold or microorganisms.

What manufacturer to choose

Especially popular and in demand for russian market are polyurethane paints of the following manufacturers:

It must be said that there are still paints from the producer of Taochem, thanks to a more affordable price and a variety of goods. Enamel, varnishes and primers Elkor Taocheim will satisfy the most demanding buyer, their scope is much wider than from other manufacturers.

Conclusion

We affordably told about polyurethane enamels, now you know what paint is in a polyurethane based, and understand the difference between the various types and types of coatings. We advise you to carefully see photos and videos in this article, to finally understand everything about these covers.

The absolute majority of modern varnish compositions are safe for people, can be applied not only for internal, but also for external work. Exists a large number of different species varnishes, characterized by the performance characteristics and composition of components. In the article, we will consider only one species - polyurethane varnishes for the floor. These varnishes are successfully used as effective safe alternative widespread lacasted with high content Harmful volatile chemical compounds based on various aggressive inorganic solvents. In developed foreign countries The share of water varnishes exceeds 50% of all coatings, and in housing construction and furniture industry this amount increases to 90%.

Depending on the specific type, polyurethane varnishes can be used to cover wooden and concrete floors, furniture, external and internal wall surfaces, etc.

Varnishes on water based In the dry residue, at least 40% of the substance have, due to which the cost is reduced in comparison with the chemical solvents previously used. Polyurethane varnishes are distinguished by increased indicators of physical strength and plasticity. Perfectly opposed hard ultraviolet rays, not afraid negative impact Natural precipitation and temperature drops have high wear resistance, do not form microcracks by time of sharp shock loads.

To reduce the cost, polyurethane varnishes may be slightly diluted with acrylic, such compositions form a separate group of acrylic polyurethane coatings. The reduction in value occurs simultaneously with a slight deterioration. performance characteristicsThis should not be forgotten by consumers.

Depending on the method of preparing for use, polyurethane varnishes can be two types:

• one-component. The most simple in use is in most cases suitable for use without prior preparation. Additional dilution of solvents are allowed only in the case of a minor thickening caused by long-term storage or disruption of packaging tightness;
• two-component. More complex varnishes, two components that are responsible for the reactions of polymerization should be mixed before applying. More complex in use, the price is superior to the first. Different with significantly improved operational performance.

Important. During drying, two-component varnishes are highlighted in the air chemical compounds. In the work of work, it is necessary to take measures to protect the respiratory organs and ensure effective natural ventilation of the room.

Polyurethane varnishes penetrate deeply into the surface, due to this, the indicators of strength and wear resistance are improved. Depending on the type external surface Can be glossy, semi-units, semi-wave and matte.

Short list of the most famous polyurethane varnishes for floors

Among manufacturers, we chose only those that have positive reviews from numerous consumers.

The outer surface may be matte, semi-wax, semi-men or glossy, is used to cover wooden floors. interior premises. The upper film is characterized by high strength indicators, does not respond to most household fluids, including detergents. Resistant to long-term direct contact with water, not afraid of shocks. Differs high indicators of plasticity. Application technology allows self-leveling varnish - the surface becomes perfectly even. It will quickly dry, with effective natural ventilation, you can apply three layers during the day - the timing of painting work is significantly accelerated.

The first layer raises the pile on the boards, which requires additional grinding. The time of complete drying is no more than two hours, it is required to be quickly applied, it is desirable to use wide rollers, only hard-to-reach places are processed with tassels.

Zar Ultra Exterior.

For external work. It is often used to cover the wooden floors of the arows, the veranda, bath, etc. quickly dries, has increased indicators to abrasive abrasion. Innovative additives are added to increase resistance to hard ultraviolet radiation. By efficiency and duration, the coating is much superior to the existing domestic counterparts. Drying time up to two hours is not afraid of temperature drop, does not exfoliate from the surface of the entire service life.

It has special inclusions, warning wheels rotting processes and inhibiting reproduction of various microorganisms and vegetation.

Polyurethane varnish UR-293

The main purpose is for the finish coating of concrete floors, allowed to be used on wooden surfacesfor internal work. Has high values \u200b\u200bof wear resistance and impact strength, which makes it possible to use varnish not only for residential premises, but also for warehouses, industrial and public buildings. One-component, solidification occurs at the expense of moisture contained in the air. The coating is resistant to the effects of household and industrial chemicals. Diluent - xylene or solvent, glossy varnish, drying time within 36 hours, the maximum hardness occurs after seven days after coating concrete floors.

Technology of applying polyurethane varnishes on wooden floors

For the production of work, you need to prepare felt rollers, brushes, if possible, it is recommended to use pneumatic paint collars.

Tools should be washed with solvents, the particular brand is specified on the package in the instructions of the manufacturer of polyurethane varnish.

Very important. Many rollers and tassels at the beginning of varnishing can leave the smallest villi on the surface. Experienced builders It is strongly advised before the start of production of work several times to roll them on the segments of the boards. This will give the opportunity to get rid of a fragile pile. Keep in mind that it is impossible to get the fallen patches with a dried cover, you will have to remove the entire layer.

Step 1. Prepare a surface. The floor is cleaned of dust and dirt, vacuuming. If there is a big pile, then wooden coatings You should polish and re-add. Timber must be dry, the presence of fatty and oily stains is strictly prohibited.

Step 2.. Gently with pussy walk around the perimeter of the room. The width of the coating line should be at least ten centimeters, it will eliminate the likelihood of wall pollution. If there are concerns, it is better additionally around the perimeter of the wall of the floor from the floor to crack construction paper scotch. After a complete end of work, it is removed without any problems.

Step 3. Prepare lacquer for use. If it is planned to use a pneumatic paintopult to cover, then the lacquer needs to be divorced by about 15% of the initial consistency. Two-component varnishes are preparing taking into account the recommendations of manufacturers.

Important. It should be borne in mind that two-component varnishes after a minor thickening can no longer be diluted. Prepare them should only be used in the amount that can be used for 30-40 minutes.

Step 4. Pour a portion of varnish into a special container for soaking the roller and start neat varnishing. The roller can not move quickly, with such movements can be formed by air bubbles. If such a problem has been discovered, then in these places it follows a few times to walk the roller, movements should be slow and smooth.

Practical advice. Some species polyurethane varnish Have an unpleasant property - raise the smallest pile of wood. Carefully read the instructions before purchased. The raised pile will have to grind and only after that apply the second layer. Experienced malariers advised to acquire better varnishes, not raising a pile. They are somewhat more expensive, but by reducing the number of work, the increase in cost is leveled.

Step 5. After the surface surfaches (stop sticking), the second layer is applied. The number of coatings of at least three.

Carefully follow the thickness of the varnish, there should not be noticeable tracks from the roller or tassels. Special attention Clean the finish layer, correct the mistakes will be very difficult. The surface will have to grind and apply another layer, and this increases the time and cost of coating.

Polyurethane varnish technology for concrete floors

Most often concrete bulk floors are ladched, the finish coating of varnish can significantly improve the operational and design characteristics of the floors. For the production of work, you can use the same tools as for wooden. The prerequisite - the surface should be as smooth and completely dry.

Step 1. Paul preparation. If necessary, align and clean from dust.

Step 2. Primer. If polymers are missing in the structure of the bulk sex, then the primer is required, it not only connects the smallest particles of the solution, but also forms a hermetic coating on top. Due to this, consumption of expensive polyurethane varnishes is significantly reduced. The primer is applied by the usual method, taking into account the manufacturer's instructions.

Step 3.. Preparation of varnish to use. Professionals are recommended for concrete floors to use two-component polyurethane varnishes, according to their physical and operational indicators, they maximize the requirements. Only the amount of varnish that can be quickly used is needed.

Step 4.. Applying a varnish coating. For those who wish to have completely exclusive floors, it is recommended to make unique drawings on the surface before applying a varnish or use ready-made printing stencils. Such floors can create a spectacular design of rooms in various styles.

Step 5.. Tassel walk through all uncomfortable places, including near pipes heating system. If the varnish dries very quickly, and the experience of working with a tassel is not enough, then only those parts of the floor can be prepared short term Covered with varnish. Next again, you need to work a tassel and prepare the next section of the floor.

The number of layers is determined by the experimental way, but in most cases there must be at least three. For decorative coating Concrete bulk sex is recommended to select only transparent glossy varnishes of the highest quality. The service life of such coatings is at least twenty years.

Practical advice. Self-leveling concrete floor coatings to increase strength and wear resistance are various mineral and chemical additives in their composition, some of them are incompatible with the ingredients of polyurethane varnishes. Before purchasing a large battleship, you need to make sure of their joint use. Carefully examine the instruction of the floor mixture and planned to use varnish. If for some reason there is no such possibility, then it is necessary to test them to determine their compatibility on a small and inconspicuous floor.

With the help of high-quality and properly applied polyurethane varnishes for the floor, you can improve appearance All rooms, increase the service life of coatings, increase the comfort of accommodation in the premises. A wide selection of various brands and species allows you to select varnishes separately for each room, taking into account its specific destination. Environmentally safe varnishes on a polyurethane-based state controlling organizations are allowed for use without restrictions.

Solvents are often used to dilute paint materials (paints, varnishes, enamels, glue). They are all sorts of species. And each of them has its own characteristic properties. In this article we will tell you in more detail that the solvent is for acrylic paints, oil colors, varnish, glue.

Acrylic solvent

This composition is often used to dissolve polyurethane resins, two-component acrylic paints, primers. Despite the fact that acrylic paints can be diluted with conventional water, the use of this solvent significantly accelerates the process when the coating layer is drying. In addition, its use allows you to achieve a flat and smooth painted surface without the formation of any heights and a dairy plaque.

The acrylic solvent has a type of transparent fluid with a specific smell. It is produced in several versions, which differ from the drying time (Madle, more and more, and bye). And are applied in certain conditions, depending on the humidity and temperature of the air. For example, in cold weather it is better to use the composition with a high speed of evaporation. On a hot day, the opposite is desirable to apply a solvent with a low evaporation.

Store the composition is preferably in well ventilated, cool and dark rooms (without access to UV rays to packaging). It is also important that in it the main rules and standards fire safety. The packaging itself should be tightly closed and located in a vertical position.

Solvent for oil paints

For dilution of paints on an oil basis, the following solvents are often used: White spirit, gasoline, acetone, turpentine. Tell the most detailed about each of them. So, White Spirit is produced in the process of oil distillation. It is used to dissolve alkyd, bitumen, oil paints, as well as for rubber, olife, epoxy and polybulathelomethalate. Instead, NEFRA 150/180 (as a substitute) can also be used. Skipididar is manufactured in an industrial method when processing wood pine.

The following types are distinguished: dry, steam, sulphate, extraction. The best is the one that contains large quantity Pinen. Use it to dilute the paints of oil, glyphthal, bituminous, pentaphthalicable LKM. Acetone is passing by treating cumol hydroperoxide. it good solvent varnishes and paints based on vinyl polymers. It is also used to dilute polyacrylate, epoxy resin., chlorinated, vinyl chloride copolymers.

Solvent for glue moment

The glue solvent is necessary not only in the process of applying the composition, but then when the mixture has already dried. For example, there are cases that you need to disconnect some details or rain the stain. The best solvent for superclause is, as a rule, ethyl acetate, xylene, butyl acetate and acetone. And sometimes it is sometimes diluents for acrylic and polyurethane varnishes and paints. Let's tell about them in more detail. Ethyl acetate is used for nitrocellulose and polyacrylate paints and varnish materials. Like acetone, almost all polymers dissolve.

The xylene solvent - consists of a mixture of isomers, which is obtained from coal or oil. Therefore, it is divided into stone and oil. It is used for phenolic, alkyd, chlorinated, bitumen, epoxyphenolic paints and varnish materials. Butyl acetate is manufactured by heating acetic acid and butyl alcohol with the addition of catalysts. It is used to dilute the esters of oil, chlorinee, fats, cellulose. And if you add a small amount of butyl alcohol to it, it is capable of preventing the formation of an LKM film.

Solvent for varnish

In order to dilute the varnish, the following solvents can be used: benzene, p-4, p-4a, 646. If we talk about the first - benzene, then it is obtained by pyrolysis of raw stone benzene and oil. It is an excellent thinner for rubber, fats, oils, wax, cellulose, esters, silicone and cresolformaldehyde resins. In the event that it is necessary to dissolve polyurethane varnish, then the compositions of the P-4 and P-4A will also fit well.

The main ingredients of these mixtures are: ethers, ketones, hydrocarbons. And also includes some components that are capable of significantly increase the efficiency of dissolving LKM. They are used for many paints and varnishes - varnishes, putty, primers, enamels. 646 Solvent Suitable for surface treatment before application of LKM. (degreases it), and also effectively dissolves nitroemal and nitroleki.

The areas of application of solvents and diluents are extensive. While doing repair work We inevitably deal with solvents for varnish, enamel, paints. In construction use solvents rust, concrete, liquid glass, liquid nails, mounting foam and other materials. The solvents constantly enjoy the artists, and in everyday life they help us remove complex pollution. Our article will help to understand this big topic so that you can quickly answer the question: what solvent is better to apply in each case.

Solvent and diluent: What is the difference?

The concepts "solvent" and "diluent" are often used as synonyms. However, there is an important difference between them. If we speak in a simple language, the solvent interacts directly with the film-forming (curing) component.

For example, gasoline is a popular solvent for oil paints. It dissolves the binder, so it can dilute the paint for applying and at the same time can remove the stains of dry paint.

The diluent does not dissolve the substances forming the film, and can only reduce the viscosity of the composition. For example, water well dilutes the water-emulsion paint, but it will not be able to wash off the dried.

Types of solvents

For convenience, we divide all solvents into the following groups:

1. Solvents for paints and varnishes (paints, enamels, varnishes), as well as adhesives and primers
2. Solvents building materials (Bitumen, concrete solvents, foam, rubber, rust, etc.)
3. Household solvents (spots from oil, fat, scotch, etc.)
4. Artistic solvents

Solvents for paints and varnishes

Almost all solvents for varnishes, paints and enamel are volatile organic substances Low boiling point. These properties provide rapid drying of the compositions after applying.

Solvents are there:

- homogeneous - based on a single substance or a mixture of homogeneous substances (for example, toluene);

- Combined - based on several homogeneous solvents in a certain proportion (for example, P-4 \u003d toluene + acetone + butyl acetate).

As a rule, combined is characterized by higher efficiency and address action.

With our table, you can easily understand what solvents for which paints are applied.

Appointment of solvents

Others beneficial features Solvent data:

- cleansing and degreasing surface;

- Removal of LKMs with brushes, rollers, spatulas and other tools.

Video about how the solvent is rinsed the paintopult

Solvents for paint removal: fresh and old

If, when performing work, the paint stains were not where it is necessary (blurred furniture, gender, glass), it can be removed by solvents specified in the table. True for delicate surfaces (wood, laminate, plexiglass) should not use the combined compositions of the R-646 type. It is better to use homogeneous and be sure to check their action at an invisible area.

Special solvents are available for removing old colors with large squares. They will help remove paint from the walls, with metal products etc.

Solvents of building materials

Removal of frozen construction solutions Often causes serious difficulties. Manufacturers have done everything to make bitumen, concrete, installation foam, and the like as resistant to chemical exposure. What solvents will help in this case.

Concrete solvent, cement, grout - a mixture of concentrated acid, protective substances for metals and inhibitors.

Liquid glass solvent -from the tools you can wash off with warm water immediately after applying. Frozen can be removed by organic solvents

Solvent for foam assembly -fresh foam is easily removed by ethyl acetate or solvents based on it (for example, P-645, 647). Solvent of frozen mounting foam can be considered folk remedy "Dimeksid" (sold in pharmacies). Also "Dimeksid" - excellent solvent Superclaud..

Solvent of liquid nails - uncomfortable solvents are removed on mineral base or water. Frozen can be removed mechanically or by heating with a hairdryer to a temperature above 50 ° C

Rust solvent - Special compositions based on phosphoric acid, tannin, oxycarboxylic polynoxic acids.

Silicone solvent ( silicone sealant, glue) - Along with special compositions from producers, sealant and glue can be used. acetic acid or White Spirit.

Solvents of polymers:

— PVC- tetrahydrofuran, cyclohexanone for several days;

— polyethylene - xylene, benzene when heated;

— polyurene Foolder - It is removed only by fresh special solvents from manufacturers.

Rubber and rubber solvent -toluene and other organic solvents are suitable for removal of the substance (rubber dissolves, rubber swells and collapses)

Bituminous Mastic Solvent -toluene, solvent, gasoline, White spirit

Foam solvent -acetone solvent R-650

Solvent for paraffin and wax- Kerosene, White spirit, gasoline, acetone.

In the next article, we will tell you about small solvents and solvents that artists enjoy.
