The basic components of coatings

A film-forming material is the main component of the coating film, including grease, oil processing products, cellulose derivatives, natural resins and synthetic resins. Film-forming materials also include sections of non-volatile reactive diluent, which is firmly attached to the coating material to form a continuous film mainly be coated surface, underlies the coating determines the basic properties of the coating.
2 aids such as defoamers, leveling agent, there are some special functional additives, such as substrate wetting agents. These additives are generally not formed, but the coating film is formed on the base material and the durability of the process plays an important role.
3 pigments are generally divided into two types, one for colored pigments, common titanium dioxide, chrome yellow, etc., there are kinds of extender pigment, it is often said of fillers such as calcium carbonate, talc
4 the solvent include hydrocarbon solvents (mineral spirits, kerosene, gasoline, benzene, toluene, xylene, etc.), alcohols, ethers, ketones and esters. The main role of solvent and water is to enable the formation of a film forming binder dispersed viscous liquid. It helps the construction and improvement of certain properties of the coating.
According to the main film-forming substance used in the coating can be classified into oil-based paint coating, fiber coatings, synthetic coatings and inorganic coatings; traits of the coating or film can be divided into solution, emulsion, sol, powder, bright, colorful art paint extinction and and so on.
