Epoxy paint is a kind of industrial coating that has developed rapidly in recent years. Generally speaking, the paint with more epoxy groups in the composition is called epoxy paint. The main varieties of epoxy coatings are two-component coatings, which are composed of epoxy resin and curing agent. There are also some one-component self-drying coating varieties, but their performance is somewhat different from that of two-component coatings.
The main advantages of epoxy coatings are strong adhesion to inorganic materials such as cement and metal; the coating itself is very corrosion-resistant; excellent mechanical properties, wear-resistant and impact-resistant; it can be made into solvent-free or high-solid content coatings; Solvent, heat, and water resistant; this film is non-toxic.
The disadvantage is that the weather resistance is not good, and it may become powdery when exposed to the sun for a long time, so it can only be used for primer or interior paint; the decoration is poor, and it is difficult to maintain the gloss; Poor; many varieties require high temperature curing, and the cost of coating equipment is high. Epoxy resin coatings are mainly used for floor coatings, automotive primers, metal anti-corrosion, chemical anti-corrosion, etc.
