Ingredients of Decorative Paint and Coatings

Coatings are usually viscous liquids based on resins or oils, with or without pigments and fillers, and prepared with organic solvents or water. New types of coatings, such as powder coatings, have also appeared in solid form. Each type of coating, whether liquid or solid, should consist of at least two or three basic ingredients. That is the main film-forming substance, the secondary film-forming substance, and the auxiliary film-forming substance. Some coatings have specific functions, such as high-temperature resistance, cold resistance, and radiation protection. Coatings are widely used in construction, ships, vehicles, and metal products.

Coatings consist of film-forming substances, pigments, fillers, additives, functional components, organic solvents or water.

The film-forming substance is s the main component of the tough and continuous film that is bound to the pigment, including polymer grease, resin or synthetic resin, and inorganic polymers. The pigments are mainly inorganic pigments. Organic pigments are gradually increasing in highly decorative coatings. In addition to generating color and providing hiding power in the coating film, the pigment can also enhance the durability and abrasion resistance of the coating film.

Filler: It is a white or slightly colored inorganic pigment with poor hiding power. It is mainly used to increase the strength of the coating film and reduce the cost.

Additives: Generally used to improve the performance of coating products and coating films.

Functional component: It is added to make the coating have a specific function.

Solvent: It is a volatile liquid used to dissolve the base material.
