Problems solved by technology

[0002] Existing high-temperature baking varnishes and low-temperature PU coatings either need to be baked at a higher temperature to cure, wasting energy, or require a longer drying time (two-component PU paint) for 3-4 hours in summer and 5-12 hours or even longer in winter. The production efficiency is low, and the two-component PU paint contains expensive isocyanate, which has a great impact on the human body and the environment
