ISO 1518 Paint Surface Scratch Resistance Tester
ISO 1518 Paint Surface Scratch Resistance Tester is a laboratory testing device used to evaluate the scratch resistance of paint films and coated surfaces. It is suitable for automotive surface coatings, metallic paints, coil coatings, ink coatings, and other material surfaces. By applying pressure through a controlled scratch needle, it creates repeatable scratches on the sample surface to determine the coating's scratch resistance.
Application
Road/rail/marine coatings;
Textile/printing surface coatings;
Aerospace coatings and materials;
Automotive and component surface coatings;
Comprehensive material surface scratch resistance testing.
