Polymer paint is a composition that is produced using waste-free technology. These mixtures are environmentally friendly, and are formed from polymer powders that are applied to the painted surface of various products. If the coating is carried out in the factory, then after processing the surface or product with polymer paint, the base is heated and held at a certain temperature for several minutes.
Key Features
Polymer paint has many advantages, it is cheaper, because it does not have solvents, which in liquid formulations play the role of carriers for film formation. The curing time of such compositions is reduced, since film formation occurs at high speed. The coating can be done in one layer, which distinguishes this composition from conventional paints, which require multi-layer application with repeated drying.
In the process of work, such complex operations as fine-tuning to the desired value of the viscosity parameter, as well as control of this value, are excluded. Powder formulations are supplied readyform for ease of application. After reviewing the range of such products, you can choose from 5000 colors, textures and shades. After using the compound, the spray equipment is easy to clean, as it is much easier to remove the powder than multiple layers of liquid paint.
Polymer paint creates a single-layer, rather thick coating, which allows you to save money due to the 100% dry matter content. When applied under pressure, powder mixtures lose up to 4% in volume, which is an advantage over liquid materials, which lose up to 40% in quantity. The resulting coatings have excellent physical and mechanical properties, and the surface is characterized by chemical resistance.
Main varieties of polymer paints
If you are interested in polymer paint, then you should familiarize yourself with the range of these products. Such materials may be polyester, epoxy, polyurethane or epoxy-polyester. The main advantage of epoxy paints is an excellent combination of physical, mechanical and electrical insulating qualities. Such coatings are characterized by high adhesion, chemical resistance and mechanical strength. The bases are resistant to acids and alkalis, fuel, oil, water, which allows the use of epoxy composition for internal and external protection of main pipelines.
If you plan to use epoxy resin paints, you can use them to create a layer,the thickness of which can reach 500 microns. In this case, good hardness, high impact strength and elasticity will be observed over the entire surface. However, there are also disadvantages of the coating, which are expressed in limited weather resistance. Outdoor areas may experience chalking and a tendency to yellow due to overheating.
Area of use of epoxy resin paints
Epoxy polymer powder paint is used to obtain hard coatings that are resistant to chemicals and solvents. The consumers of such powders are the fields of radio engineering and electrical engineering; in these areas, coatings replace many types of complex electrical insulation. Epoxy can be applied to electrical cabinets, office fittings, medical equipment and home supplies.
Area of use of polyester resin paints
Similar compositions are used for finishing household items, garden, medical, metal, office furniture, sports equipment, as well as electrical equipment, etc. Polyesters are in great demand due to their unique decorative qualities. Modern technology for the manufacture of powder paints has made it possible to expand the color range of coatings and achieve different textures.
Fields of use of polyester and polyurethane polymer paints
PolyesterPaint for polymer coatings is used for the treatment of tourist accessories, agricultural vehicles, automobile wheels, as well as aluminum and steel profiles for door and window openings. Polyester formulations are versatile as they can be used for indoor and outdoor applications. As a result, it is possible to obtain a glossy surface, the gloss of which reaches 90%. Alternatively, you can choose a polyester blend that allows you to create a matte or semi-matte finish.
Polyurethane paints based on polymers are characterized by stable gloss, water and weather resistance. They are resistant to mineral oils, fuels and solvents. Polyurethane paints are used to protect products that are subject to abrasion and abrasion. They can be applied to some types of chemical equipment and containers designed to store gaseous and liquid chemicals. It is possible to apply polyurethane paints as a primer before using other powder paints such as polyacrylic or epoxy.
Assignment of polymer paint for metal
Polymeric paint for metal contains a solvent, special additives, polystyrene, and pigment. This mixture is also called liquid plastic and is a solution of crushed polystyrene in solvent or toluene. Considering the polymer composition for metal, PS-160 can be cited as an example. This mixtureused for processing pipelines, protecting the metal structures of swimming pools, for covering metal floors, as well as for painting the load-bearing elements of buildings. As for pipelines, heating mains should also be included here. Metal floors can be covered on ships, inside production and storage facilities. This resin floor paint can protect surfaces that are constantly in contact with water.
Purpose and properties of acrylic polymer compounds
Acrylic polymer paints can be used for interior and exterior work in the field of facades, as well as for the repair and painting of metal roofs. Before applying this composition, it is recommended to apply a primer. Among the characteristics of these mixtures, one can single out a long service life, which reaches 20 years. It is impossible not to mention the possibility of obtaining a durable and durable coating, excellent resistance to high humidity, temperature extremes and exposure to the sun. Among other things, these paints are heat and frost resistant. After being applied to the surface, they dry fairly quickly, forming a thin, smooth and extremely durable protective film. During operation, it shows the qualities of resistance to chemicals and various detergent mixtures. Applying acrylic paints is very simple, they do not require the use of expensive equipment. Acrylic polymer compounds have high adhesion to the base, they are environmentally friendly and harmless to he althhuman.
Polyurethane polymer paint for concrete
This coloring matter acts as the most resistant to the influence of negative factors. Surfaces are not afraid of oil products, chemicals and solvents. Thanks to this characteristic, polyurethane paint can be used for painting garages, hangars, industrial premises and basements. The surface after coating with this agent acquires the qualities of protection from impacts and mechanical damage. The layer can be glossy or matte, and you will spend about 400 g per square meter. Before painting, the surface is treated with a primer, and then polyurethane paint is applied in 2 layers. The second of them should be applied only after the first has completely dried, which will happen in about a day.
Conclusion
Among the polymer paints, you can find universal ones, which is epoxy, which can be used for interior and exterior use. The advantage of this dye is that it is able to replace the primer, allowing you to save money.
