The polymer coating is created on the basis of powder paint. It is a new environmentally friendly, non-waste technology. Nowdays, it is considered to be one of the best technologies for coating. In short, the technology can be described as follows: the powder paint is sprayed onto the surface of the article using an electrostatic field, then it is kept in special chambers at high temperature.
In the last decade, powder painting technology is increasingly replacing traditional methods. About 15 percent of all products in the world are painted with this method. And the number is constantly increasing. What is the difference between powder paints and ordinary liquid paints? The main advantages of polymer coatings are their durability, strength and protective functions. A layer of elastic plastic with very high resistance is formed on the painted surface. That is thanks to the new technology. Office and home metal furniture, commercial equipment, sports equipment are just a few examples where polymer coatings have proven themselves.
Industrial painting with conventional liquid paints means controlling viscosity and adjusting it to the desired value. The use of powder paints excludes these complex operations, which ultimately provides economy and greater stability of the painting quality. Elimination of streaks on vertical surfaces and wrinkling of coatings during drying. The possibility of obtaining thick single-layer coatings (due to 100% dry matter content) instead of more expensive multilayer coatings in the case of liquid paints. There is also less shrinkage and porosity of the foam due to the absence of evaporation in the solvents.
Compared to conventional, organic-soluble paints and varnishes, polymer coatings are chemically resistant. They are highly resistant to solvents, alkalis, acids, gasoline, lubricating oils and other compounds.
They also have increased anticorrosive properties. Polymer coating can be affected without prejudice to the term of operation by the increased temperature, either constantly or periodically. The polymer coating is harmless. The new coloring technology eliminates environmental problems since flammable and toxic liquid solvents are not used. Just remember that everyone has powder-painted gas stoves and refrigerators at home.
Another significant advantage of powder paints is the almost boundless color palette, as well as shades and textures. The surface gains properties that during the using traditional technologies are unattainable or their costs is several times higher.For example, golden, silvery and aluminum metallics, fluorescent paints. There are also unusual shades: for example, a series of colors "antique" which will stylize a surface under ancient copper, bronze or silver objects. When painted, shades are controlled by the degree of gloss, forming glossy, matte and semi-matt surfaces. A variety of colors complement special effects - "moiré", "granite" and others.
