The paint is mainly used in combination with base paint and colored paint, is a transparent finishing varnish, is inseparable from the base paint in a spraying process, and is generally sprayed with the base paint firstly and then with the varnish, wherein the varnish provides gloss and a protective layer for the base paint. The varnish coated in the original factory is high-temperature baking varnish generally, the baking temperature is 120-150 ℃, and the baking time is about half an hour. The self-drying varnish is generally used for paint layer repairing operation in the automobile maintenance industry, can be naturally dried at room temperature and can also be baked at low temperature, and the baking temperature can be set to be 50-80 ℃. At present, the varnish materials adopted by original factories are mainly single-component paints cured at high temperature, namely acrylic resin added with amino resin or polyester resin and the like, the varnish materials commonly used for refinishing paints are mainly two-component acrylic resins cured naturally (the two-component acrylic resins generally comprise main paint, curing agent and diluent), and the main components of the two are acrylic resins.
