Product No: LS-B30
The LS-B30 Coating Scratch Resistance Tester is a specialized device for testing the scratch resistance of material coatings. It applies a specific axial force to the test sample using a standardized scratching steel bar, scratching at a specified angle and speed in the forward direction. The device accurately simulates the contact of a sharp tool with the coating, thereby assessing the strength of coatings on easily accessible solid insulating components or printed circuit boards, verifying their resistance to puncture risks, and providing testing conditions that meet relevant requirements for the quality assessment of material coatings.
