Coating refers to the ability to form a dense, continuous and uniform film on the surface of an object under certain conditions to play a role in protection, decoration or other special functions (insulation, anti-rust, anti-mildew, heat resistance, flame retardant, anti-static, wear-resistant etc.), a class of liquid or solid materials.
What is painting?
The coating is applied to the surface of the object with certain equipment and methods, and then dried and cured by natural or artificial methods to form a uniform thin film coating. This process is called painting.
Classification of paint
(1) According to the coating form, it can be divided into water-based coating, solvent coating, powder coating, high-solid coating, etc.;
(2) According to the construction method, it can be divided into brush coating, spray coating, roller coating, dip coating, electrophoretic coating, etc.;
(3) According to the construction process, it can be divided into primer, intermediate paint (secondary primer), top coat, top coat, etc.;
(4) It can be divided into decorative coatings, anti-corrosion coatings, conductive coatings, anti-rust coatings, high-temperature-resistant coatings, temperature-indicating coatings, thermal insulation coatings, flame-retardant coatings, invisible coatings, antibacterial coatings, etc.;
(5) It can be divided into architectural coatings, can coatings, automotive coatings, aircraft coatings, household appliance coatings, wood coatings, bridge coatings, plastic coatings, paper coatings, etc.
(6) In the field of chemical industry in CHINA, coatings are divided into 17 categories according to the main film-forming substances.
