Glyptal resins derived from three components: oil, multi-molecular alcohol (glycerol), many basic acids (phthalic anhydride). Depending on the oil content of three types of glyptal resin: long-resin containing 55-80% oil, divided into driers and polusikkativy. They are applied with a brush and air-dried, medium-tar, containing 45-55% oil, driers and are divided into polusikkativy. They are applied by brush or spray out and dried in air or in dryer; short-resin oil content of less than 45%, divided into polusikkativy and driers (nevysushivayuschie). They are applied from the spray gun and air-dried in the dryer or, if the resin termotverd eyuschie.
Aminoplastovye resin (Melamine and urea-formalin) are the products of synthesis by-products of chemical processing of coal. Some manufacturers mix them with glyptal resins. Polymerization of these resins at elevated temperatures. Melamine polymerize at lower temperatures than urea-formalin resin. Aminoplastovye resins are mainly used in the automotive industry. Acrylic resins are the result of synthesis of refined petroleum products. There are two groups of acrylic resin: thermoplastic and termotverdeyuschie.
Thermoplastic resins soften at elevated temperatures. Drying occurs by evaporation of the solvent and is called the “physical drying.” Dried quickly, the paint resin gives a good shine and high resistance to the harsh climate. Thermoplastic resins to highly dilute the solvent. They are used in car body repair and automotive applications. Termotverdeyuschie resins are dried at high temperatures (in the drying chamber), are highly resistant to various climatic conditions and to chemical substances, provide a good shine.
