Hundred grid knife test board 1MM paint film adhesion test instrument
Product parameter
01. The guide gauge is designed and manufactured according to BS3962-6 and G84893.4-85 standards, which is convenient and simple
02. Cut spacing: 1m*11, 1.5m*11, 2m*11, 3m*7
03. Cut length: 20-35m
04. Number of cuts: 7-11 \\
This instrument is mainly used to determine the adhesion of paint by cross-cut method, and is suitable for laboratories or construction sites under various conditions.
Working principle and scope of application
This instrument cuts and penetrates the coating as a grid pattern with a tool of a certain specification. The finished graphics are classified into 6 categories, and the adhesion effect of the coating from the substrate is evaluated. It is suitable for measuring the surface paint of plastic and wood furniture. The film thickness is less than 250m, the adhesion strength of the paint film to the substrate
Suitable for spraying plastic and wood furniture surface adhesion strength and fastness or the strength of the combination of the base paint
Length: 120mm
Width: 80mm
Thickness: 0.9m
DV: 3m0
Operation method
The test piece must be customized according to SR1514 and 1S02828
Place the test piece on a flat plate with sufficient hardness
Hold the guide gauge (100 grid board) so that the bottom surface is completely flush with the surface of the finished surface coating
Use a uniformly pressed 100 grid board, use a sharp blade to cut the knife at a cutting speed of 20-50m/s without shaking
Rotate the 100 grid board 90 degrees, repeat the above operation on the cut cut to form a grid pattern
Use a tape that meets the standard to stick to the crossed surface and tear off the tape to observe the adhesion strength of the coating on the surface

Precautions
1. All incisions should penetrate the coating, but not too deep into the substrate
2. If the coating is too thick and hard to penetrate the substrate, the experiment is invalid but it should be stated in the experiment report
3. The test tape must be a 600 special test tape produced by 3M in the United States
Stick the tape on the entire grid, and then tear it off at the smallest angle. The result can be obtained according to the ratio of the glued area on the surface of the paint film
4. The experiment should be carried out at a temperature of 23±2C and a relative humidity of 50±5%
