What is Cross Cut Test?

Cross cut test is generally a test to define the adhesion of the coating or printing on a subject.

It can be divided into ASTM 5 levels, the higher the level, the stricter of the requirements. For the glass with silkscreen printing or coating, usually the standard level is 4B with flaking area <5%.
