 . Features determined by cross-cutting performance test film adhesion technical characteristics: the grid graph cut and penetrate the paint matrix, classification and evaluation by six separate the film from the substrate resistance. . Technical parameters cutter: 11 blade, blade distance: 1mm, 2mm, 3mm Note: Cross cutting purposes: Determination by cross-cutting performance test film adhesion technical characteristics: to cut and penetrate the cell matrix graphic film, according to Classification and evaluation of six separate the film from the substrate resistance. Steps - the coated device with cross-cut cross cut out on the grid graph, the incision until the substrate; - the brush with the brush five times the diagonal direction, with adhesive tape and then pull on the incision; - observation grid region case, a magnifying glass available 

 Hatch result of the standard level of adhesion following ISO rating: 0ASTM Grade: 5B cut the edge of the perfectly smooth, without any falling off the edge of grid 

 ISO rating: 1ASTM Grade: 4B intersection of the cut are small pieces falling off, broken cross-cut area not more than 5% of the actual 

 ISO rating: 2ASTM Grade: 3B cut edges and / or the intersection have been falling off, an area greater than 5%, but less than 15% 

 ISO rating: 3ASTM Level: 2B along the cut edge of a large part of the peeling off or the whole, and / or part of the grid was peeling off the entire piece. By peeling off the area of ??more than 15%, but less than 35% 

 ISO rating: 4ASTM Grade: 1B cut edge of the large flake / or some part of some or all of peeling off the grid, the area designated cell area is greater than 35% but not more than 65%
