Overview
TR 5001/3 Single Face Cross Hatch Cutter is a tool for evaluating coating adhesion, commonly used for coating mass inspection and coating process control. It evaluates coating adhesion by marking a series of lattice patterns on the coating surface and then using tape testing. The product is made of wooden handle material and high-quality alloy steel blades. The tooth spacing is 1.5mm and the number of teeth is 11. It is suitable for hard substrates with film thickness 61 μm~ 120 μm or soft substrates (wood, plastic) with film thickness < 120 μm.
Features
1. Ergonomic handshake design, effortless to use
2. The blade can be easily replaced
3. Blade material: high-quality alloy steel
4. Blade top width: less than 0.05mm
5. Blade angle: 30 ° +/- 1 °
Principle
Adhesion Cross Hatch Cutter evaluates the adhesion of a coating by drawing a series of lattice patterns on the surface of the coating, then covering the scratched area with tape using the appropriate tool and then quickly tearing off the tape. It provides qualitative or semi-quantitative information about the bond strength between the coating and the substrate.
Applications
Coatings mass inspection, coating process control, coating research and quality control in laboratory environments
Standards
GB/T 9286、ASTM D3359、ASTM D3002、ISO 2409
Steps
1. Draw a series of lattice patterns on the coating surface
2. Cover the scratched area with tape using the appropriate tool
Step 3 Remove the tape quickly
4. Evaluate coating adhesion
Notice
• Suitable for film Film thickness 61μm~ 120μm hard substrate or Film thickness < 120μm soft substrate (wood, plastic)
• Blades are replaceable, make sure to use sharp blades
• Pay attention to safety during operation and avoid scratches
