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.
