Pencil hardness test

Pencil hardness test
Coatings generally have the functions of protection, decoration, marking, anti-fouling, insulation, etc., and they are widely used. Therefore, coating testing has become one of the most effective ways for manufacturers or individuals to verify the quality of coatings. With the development of the national economy and the advancement of science and technology, paint testing is gradually promoting the development of the coating industry to water-based, high-performance, high-grade, functional, and the prospects are more open.
