涂料常用检验方法讲义
The wear resistance of the paint film is actually a description of the resistance of the surface of the paint film to the mechanical action of friction, which is one of the important characteristics of the paint film that is often subject to wear during application. Abrasion resistance mainly depends on the type of substrate. The surface treatment and the drying process of the paint film are related to the temperature and humidity. It is actually the comprehensive effect of the hardness, adhesion and cohesion of the paint film.
