Cross Adhesion Tester Cross-Cut Tester Kit including 1mm, 1.5mm, 2mm, 3mm Paint Film Cross Adhesion Tester

Parameters:

1. the guide grid regulation according to BS3962-6, GB4893.4-85 design and manufacturing standards, with easy and simple

2. nicks spacing: 1mmX11,1.5mmX11,2mmX11,3mmX7

3. nicks length: 20-35mm

4. the number of cut marks: 7-11

Features:
1.This instrument is designed and manufactured according to the standard of ISO2409-1992, and is applicable to GB/T9286-98, BS 3900 E6. 
2.The instrument draw the grid of a certain size by a certain specification of the tools by using the uniform force, cut and penetrate the coating to be a grid lattice graphics, to evaluate the adhesion of coating on the substrate through the assessment of the full extent of the grid.
3.There are six classes of grid lattice graphics, the assessment of coating separation from the substrate resistance is showing as different classes. 
4.It is widely used to evaluate the adhesion of various coatings. It is not only to be used in the laboratory, can also be used under various conditions of the construction site.

Operation introduction:

1.the test piece must be prepared by ISOR1514 and ISO2828 regulations.

2. the test piece is placed on the tablet hardness sufficient.

3.hand-held guide lattice gauge (per cell board) so that the bottom surface of the coating material is completely and check the surface of the flat stick.

4.using all the force pressing hundred grid plate, a knife with a sharp knife mediated smooth way without wobbling to 20-50mm / S cutting speed cutting program.

5. the hundred grid plate is rotated by 90 degrees on the cut cutout draw repeat the above operation, so as to form lattice graphics.

6.clean out debris with a soft brush to draw the hair using the test piece surface lattice graphics.

7. with a standard tape affixed to the surface of cross-cut and tear from tape to observe the surface of the coating adhesion strength.

Precautions:

1.all cut through the coating should, but can not be cut into the substrate too deep.

2. as a result of the coating is too thick and hard and in the end can not penetrate the material, the test is not valid, but it should be noted in the test report.

3. the tape posted on the whole cross, and then tore off the minimum angle, the result may be in proportion to the gum off the area determined according to the film surface.

4. the test should be carried out at a temperature of 23 ± 2°c  and relative humidity of 50 ± 5%.
