Lucky - the materials are solutions of film-forming material (resin or polymer) in organic solvents or water. After drying, they form a solid transparent (colorless or color) film, when you need to protect and simultaneously preserve or highlight the structure of the painted surface, mainly of fine wood. In this case, the varnish is applied to the prepared surface of the product. Lacquer as the final layer in the multilayer coating will give him a good look and enhance performance properties. What are the lakes? bituminous paints, alkyd paints, oil paints, epoxy, and nitrocellulose lacquer coatings prepared from Bitumen Bitumen of special stamps with the addition of various resins, oils. After drying bituminous varnishes form black film is resistant to water and some chemicals. It is not enough pronounced anti-corrosion properties of bitumen films at atmospheric conditions. lakipoluchayut Oil dissolving natural or synthetic resins in the drying of vegetable oil with driers and solvents. from natural resins usually used rosin, shellac and amber. As a general rule, oil paints form a solid transparent film of yellowish color. Due to the low weather resistance coating oil paints used for finishing products indoors, such as rinse aid worn wooden floor coverings. Alkyd paints - most common in the home of the applied paint. are solutions in organic solvents, synthetic alkyd (pentaphthalic or glyptal) resins. alkyd varnish film, solid, transparent, slightly colored, has good adhesion to different surfaces, water-resistant. They are used for both internal and external works. (Although traditionally paints are rarely used in the performance of external works ). In common parlance mistakenly called alkyd varnish oil. This is wrong because although the manufacture of alkyd resins and used vegetable oils, chemical composition and structure of alkyd coatings are different from oil, and the properties significantly exceed them. varnishes, acrylic paints, acrylic water Water has some differences and advantages. Of course, most importantly - it's environmentally friendly. Aqueous acrylic paints do not contain organic solvents. Another important difference is the water paints a much higher rate of interlayer drying compared with alkyd varnish. Time for complete film formation in both types of coatings is approximately the same - 10 to 14 days. Aqueous acrylic paints do not change the color of the parquet. The dry wear resistance (by walking over the floor) water lakes superior alkyd. In general we can say that water acrylic paints are more suitable for areas with a low cross, which do not require frequent wet cleaning, such as bedrooms, nurseries, offices, living rooms, etc. In these areas, due to high wear resistance, these materials will last a very long time. nitrocellulose lacquer (nitrocellulose lacquer) is prepared by dissolving cellulose nitrate in a mixture of active organic solvents. The properties of lacquers regulate the introduction into the composition of various resins (alkyd, aminoformaldegidnyh, etc.). nitrocellulose lacquer form a solid transparent, almost colorless fast-drying film. Most of nitrocellulose lacquer is used for coating of wood products. Epoxy varnishes are solutions of epoxy resins in organic solvents. Before varnishing them hardener is added, the amount of which depends on the type of resin and hardener, the curing conditions and specified in the instructions for use. Lacquerware films possess high resistance to alkali and water, mechanical density, adhesion to various materials, but not enough weather resistance. At home Epoxy paints are often used for cooking fillings, bonding, making souvenirs and other purposes. Alcohol lacquers and varnishes by dissolving in alcohol, some natural resins, shellac, Sandarac (30-45% concentration of lacquer, varnish 15-25%). These materials provide a coating with good mechanical strength and adhesion to various surfaces, high gloss. coverings are well polished, but have a low water resistance. alkidnouretanovye Polyurethane and varnish give films with isklyuchitelnovysokimi mechanical strength and durability. They varnished hardwood floors, furniture and musical instruments. Parquet lacquer - main protection parquet from external influence. And it is from the parquet lacquer depends how many years or decades, will serve you for parquet. choosing material to cover the flooring, it is necessary to take into account the operating conditions of a room. Modern requirements for parquet lacquers include concepts such as: strength, durability, environmental, chemical resistance and etc. In addition, parquet lacquer can form a glossy, matte, semi-matt surface. What are the lakes? 1.organorozbavlyaemye 2.kislotnootverzhdaemye lakes 3. vodorozbavlyaemye varnishes Among the most popular coatings for finishing parquet and wooden floors are named: alkyd, alkyd- urethane varnish. Alkyd paints are cheap, easily repaired, their constituent solvents are not very toxic. However, alkyd paints dry long enough (about 48 h), coatings based on them are not very high wear resistance. alternative to alkyd paints are alkyd-urethane varnish, are solutions of alkyd resins with urethane groups in organic solvents. Uralkidnye alkyd paints dry faster (time of exposure to recoat varnish is 6-12 h) and have a significantly higher wear resistance. Luckey acid catalysed consist of two packs, the second is a cure which is mixed with lacquer immediately before applying to the proportion which must be indicated on the package, and is typically 1 / 10. Drying time is 1-2 hours, curing of a multilayer coating takes 1-2 days, during which not recommended to stay indoors, as it was at this time there is a maximum evaporation of solvents and formaldehyde emission from the coating. These coatings are based on formaldehyde resins, but in Europe they are no longer available and do not apply. Lacquers Water-based does not contain organic solvents and at the same time on the properties not only yield borne paints, but they also beat many of them wear resistance of coatings and detergents. Preemuschestva: Crystal-clear, no yellow tint minimal odor, water-resistant High resistance to external influences produced a glossy, semi-gloss and satin sheen Varnishes solvents are manufactured from synthetic oil resins derived from natural materials. They are very well-impregnated wood, and therefore significantly change its color. a good name for a whimsical wood: beech, ash, maple, cherry. When applied to take into account that the varnish dries up just when you access oxygen. Therefore, the need of fresh air and the temperature should not be too low. Therefore, as these coatings should not be applied thick, otherwise the lower part of the surface hardens and the result will be wrinkled. Preemuschestva: The strength of the oil coating versatility (use of indoor and outdoor) Maximum bonding wood fiber insulating layer of protection against stains.
