Problems solved by technology
[0004] At present, traditional solvent-based coatings, traditional UV coatings, and water-based coatings are mainly used in the market, but most of them have some defects. For example, solvent-based coatings contain organic solvents, which have a lot of odor, and the residual solvents evaporate for a long time, which will harm the human body and pollute the environment. UV-curable coatings contain a certain amount of active diluent, which has an odor, high humidity when drying, large surface shrinkage, poor adhesion, high viscosity, and organic solvents during spraying. The construction is limited by the shape of the profile, and thick coating is easy to crack or Does not dry back to white, but water-based coatings have low solid content, slow drying, easy to stick back at high temperature, crack at low temperature, scratch resistance, stain resistance, poor chemical resistance
