The paint film scratcher, also known as the hundred grid knife, is used to evenly draw a square of a certain size, and evaluate the adhesion of the coating film to the substrate by evaluating the integrity of the coating film in the square.
It is mainly used for the determination of the cross-hatch adhesion of coatings, not only for laboratories, but also for construction sites under various conditions.
Comply with ISO 2409, ASTM D 3359 related standards, and also apply to GB/T 9286 "Cross-cut determination of paint and varnish film"
