3.Clear coat series has a different solid content, different clear coat matching the corresponding curing agent, if the clear coat and the corresponding curing agent ratio is not correct, the adhesion will also have an impact. For example, if the curing agent content is high and the clear coat concentration is low, then the varnish clear coat layer will become brittle and tend to fall off when combined. Therefore, do not use clear coat, do not use curing agent at random, and use an appropriate curing agent.
