• Multi-blade cutter spacing: 1 +0.01mm, 2+0.01mm. 3+0.05mm. Cutter spacing and cutter types: 1、2mm with 11 teeth and 3mm with 11 teeth
• Multi-blade cutter addendum straightness: ≯ 0.003mm ≯ 0.006mm.
• Multi-blade cutter tooth tip width: ≯ 0.05mm.Temperature: 23 ± 2 ° C; Relative humidity: 50 ± 5%.
• The Hot Cross Cutter Adhesion Tester is widely used in the industries related to spraying and printing. It is a standard test method commonly used in the industry.
• The instrument is made according to ASTM D 3359 – "standard test methods for measuring adhesion by tape test"

How to use cross cutter tester:

1 . Placing the test piece on a tablet of sufficient hardness.

2. Holding the handle of the program grid, keeping the multi-blade cutter perpendicular to the plane of the test piece.

3. By using the uniform force, with the manner of not fibrillation and balance and 20-50mm/S cutting speed to draw.

4. Rotating the test piece to 90 °, repeating the above operations, so as to enable to cut a grid lattice graphics.

5. Brushing the two diagonals of grid lattice graphics by using the soft brush gently backward and forward each five times.

6. The test should be taken at least in three different locations on the test piece. If the results of three positions are different,the test should be repeated in more than three positions, and record all results. If it need to replace the multi-blade cutter, use the screwdriver to unscrew the two screws on the cutter body and change the cutter, affix the edge of cutter to the handle, then tighten the screws.

Adhesion Test Class:

• SO Class / ASTM Class / Test Results / Peeling area ratio(S)
• 0 / 5B / The incision edges are smooth, without any peeling / S=0%
• 1 / 4B / The incision at the crossing of minor peeling / 0＜S≤5%
• 2 / 3B / The incision edge and the crossing of a small piece of peeling / 5%＜S≤15%
• 3 / 2B / The incision edge and the crossing of a piece of peeling / 15%＜S≤35%
• 4 / 1B / The incision edge and the crossing of large piece of peeling / 35%＜S≤65%
• 5 / 0B / The incision edge and the crossing of a large piece of major peeling / 65%＜S
