Hardware paint, in essence, is a classification of paint, but its ingredients will be more rigorous. With the development of science and technology to improve and upgrade, the relevant industry staff for hardware paint material composition has rigorous requirements and views. Hardware paint is a kind of solid coating on the surface of the object, for protection, decoration, marking and other special use of chemical mixtures. Generally speaking, the paint is composed of film forming substances, fillers (fillers), solvents, additives and other four parts.              Hardware baking paint belongs to organic chemical polymer materials, the formation of the film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a kind of multi-functional engineering materials, which is an important industry in the chemical industry.              Hardware baking paint contains more scientific and technological components, widely used in modern science and technology and industrial fields. But there are some easy to call the paint or retained, such as latex paint, primer, top paint, etc. In general, a coating is a material that can be applied to the surface of the object to be applied and can form a strongly attached continuous film. It can be inorganic, such as copper plating, nickel plating, galvanizing and so on. Can also be organic, such as most organic polymer materials, organic polymer materials constitute the main part of today's paint market.
