SP1664

Cross-cut Tester

Introduction

TQC hundred-grid knife (also known as cross-hatch adhesion Tester), available in five models: SP1660, SP1661, SP1662, SP1663, and SP1664, is a method for measuring the adhesion of dry coatings on the surface by making a series of coating incisions. kind of tool. Draw two series of parallel lines, perpendicular to each other, to obtain 25 or 100 squares of similar shapes and sizes. In the scratched area, use a hard-bristle brush to scrub or put tape on it and then tear it off. Observe the treated coating condition and make a judgment based on the standards.

This TQC hundred-grid knife only has one hundred-grid knife. The outer packaging box is a white transparent plastic shell, not a set.

Cross-hatch method experimental evaluation

grade	describe	Surface peeling in the cross-cutting area (taking 6 teeth as an example)
0	The cutting edges are completely smooth and no lines fall off.
1	There is a small amount of coating peeling off at the intersection of the cuts, but the cross-cut area should not be significantly affected by more than 5%.
2	There is coating peeling off at the intersection of the incisions and/or along the edges of the incisions, and the affected cross-cutting area is significantly greater than 5%, but not significantly greater than 15%.
3	The coating is partially or completely peeled off in large fragments along the cutting edge and partially or completely peeled off at different parts of the grid. The affected cross-cut area is significantly greater than 15%, but not significantly greater than 35%.
4	Large fragments of the coating peel off along the cutting edge and some squares are partially or completely peeled off. The affected cross-cutting area is significantly greater than 35%, but not significantly greater than 65%.
5	The degree of peeling exceeds grade 4.
