Professional Adhesion Tester Kit with Result Comparison Chart - 3-Blade Cross-Cut Tester for Paint, Coatings, Plating & Spray Finishes Surface Testing | ASTM Standards

• This cross-cut adhesion tester is precision-engineered to ASTM D3359 standards for professional-grade adhesion assessment on painted, coated, plated, and spray-finished surfaces.
• The kit includes essential accessories for comprehensive testing: a soft-bristle brush, stiff-bristle brush, ASTM-compliant adhesive tape, magnifying lens, and a 3-blade set with cutting edges optimized for varying material types and coating thicknesses (1mm, 2mm, 3mm). A laminated 6-level result comparison chart is included for instant visual grading, ensuring accurate interpretation of test outcomes according to international adhesion classification standards.
• Multi-blade cutter tooth tip width: ≯ 0.05mm.Temperature: 23 ± 2 ° C; Relative humidity: 50 ± 5%.

1.Placing the test piece on a tablet of sufficient hardness. <br> 2.Holding the handle of the program grid, keeping the multi-blade cutter perpendicular to the plane of the test piece. <br> 3.By using the uniform force, with the manner of not fibrillation and balance and 20-50mm/S cutting speed to draw. <br> 4.Rotating the test piece to 90 °, repeating the above operations, so as to enable to cut a grid lattice graphics. <br> 5.Brushing the two diagonals of grid lattice graphics by using the soft brush gently backward and forward each five times. <br> 6.The test should be taken at least in three different locations on the test piece. If the results of three positions are <br> different,the test should be repeated in more than three positions, and record all results. <br> 7.If it need to replace the multi-blade cutter, use the screwdriver to unscrew the two screws on the cutter body and change the <br> cutter, affix the edge of cutter to the handle, then tighten the screws. <br> <br> Packing List <br> 1 ·3PCS knife blades (1mm11 teeth, 2mm11teeth , 3mm 11teeth )<br> 2 ·3M tape (19mm * 32.9m),<br> 3 ·magnifying glass-1 ,<br> 4 ·wrench-1,<br> 5 ·a brush-1 ,<br> <br> Note: <br> 1. All the incision should penetrate the coating, cut into the substrate but must not be too deep. <br> 2. If the coating is too thick and hard to penetrate in the substrate, then the test is invalid.However, <br> it should be explained in the test report. <br> 3. In some special situation or special requirements, it must be compatible with the tape method for the final determination. <br> The tape is generally 12.7mm wide translucent tape, back material is polyester film or cellulose acetate.<br> Put the tape over the whole grid, then tear off it at the minimum angle, <br> the result can be obtained according to the film surface by adhesive peeling area ratio.
