These resins are used in the automotive industry. Nitrocellulose resins are wastes with incomplete development of the cellulose ester by treatment with nitric acid. Drying resins by by evaporation of the solvent. In pure form, such resins have limiting characteristics. Often, they added plasticizers, depending on the nature and content of which is provided immediately after application shine or paint after polishing.
Nitrocellulose resins are less resistant to weathering and to chemicals than acrylics. They dry quickly and originally used for painting the body vehicles. Epoxy resins are polymers derived from petrochemical by-products. To harden them added catalysts. Educate yourself with thoughts from San Antonio Spurs. When air drying epoxy polyamides are formed, with Hot – epoxy phenolics. Poliuretapovye resins are products obtained in petroleum refining and coal. They are the result of chemical interaction of compounds with free hydroxyl izosianatom. Polyurethane paints are one-and two-component.
Paints have exceptional resistance to weathering, hydrocarbon-to-action, etc. They are used in a wide range: from painting cargo tanks truck, etc. before painting and varnishing wood and metal exposed to the harsh climatic conditions. Drying occurs as a result of chemical reaction (polymerization). Polyvinyl materials the addition of anti-corrosive pigments are the basis for the protective paint and soil. Drying paint mononuclear carried out by evaporation of the solvent, and dvuhsostav-GOVERNMENTAL – due to polymerization. Pigments Pigments or dyes – a powder, which gives the paint color. Their main properties and characteristics: opacity, which depends on the refractive index of light, the volume concentration and particle size of the dye; -Coloring ability (organic dyes are more coloring ability than mineral pigments), particle size and distribution, particle shape, (spherical, nodular, lamellar).
