Paint is a material that can be coated on the surface of an object with different construction processes to form a solid film of strong adhesion and continuous strength. The film formed in this way is commonly known as coating film, also known as paint film or coating.
Chemical raw materials can generally be divided into organic chemical raw materials and inorganic chemical raw materials: Organic chemical raw materials can be divided into alkanes and their derivatives, alkenes and their derivatives, alkynes and derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylate, carbohydrates, heterocyclic, nitriles, halogenated, aminoylates, other types; Inorganic chemical raw materials can be divided into inorganic acids, inorganic bases, inorganic salts, oxides, elemental substances, industrial gases and other types.
