เครื่องทดสอบการยึดเกาะสี (cross-cut Tester , film adhesion tester) แบบหัวเดียว กล่องอลูมิเนียม มีใบมีดให้ 3 ชุด

This instrument is widely used to evaluate the adhesion of various coatings .A high precise machined presenting 6 or 11 cutting blades with various spacing is mounted in a handle. The test is carried out by performing 2 series of crossed cuts at right angle. The obtained lattices is either brushed or cleared with adhesion tape. According to the coatings thickness and the related spacing, the results can be classified with reference to a standard scale. It has long life tool with 6 cutting edges and comfortable handle.

When applied to multi-coat system, assessment of the resistance to separation of individual layers of the coating from each other may be made.    

Main Technical Parameters:
Multi-cutting blades spacing: 1mm/2mm

Normal Packing List:
 Carrying case
 CrossHatch Cutter & Handle
 1 roll of 3M Scotch Transparent Tape (3M610)
 Brush
 Magnifier

Note:
1. All the incision should penetrate the coating, cut into the substrate but must not be too deep.
2. If the coating is too thick and hard to penetrate in the substrate, then the test is invalid. However, it should be explained in the test report.
3. In some special situation or special requirements, it must be compatible with the tape method for the final determination. The tape is generally 12.7mm wide translucent tape, back material is polyester film or cellulose acetate. Put the tape over the whole grid, then tear off it at the minimum angle, the result can be obtained according to the film surface by adhesive peeling area ratio.
