The Scratch Resistance Tester (KK01 / KK02 / KK03) is designed to evaluate the scratch resistance of plastics, films, coatings, and automotive interior and exterior materials. By applying a vertically loaded scratch stylus and moving it horizontally across the sample surface, you can quantitatively assess scratch characteristics. This helps you understand surface durability, optimize material selection, and improve product appearance and service life.
Application
You can use this tester for the following applications and test materials:
Scratch resistance evaluation of plastic molded products
Scratch property testing of film materials
Surface scratch performance assessment of coatings, paints, and sprayed materials
Scratch resistance testing of automotive interior and exterior components
Scratch durability testing of optical materials, packaging materials, and electronic housings
Scratch damage analysis during material research, development, and quality control
Standards
The tester complies with the following international standards:
ISO 19252 — Plastics — Determination of scratch resistance of plastics and coated plastics by progressive load test
ASTM D7027-05 — Standard Test Method for Instrumented Indentation Test for Plastics (Scratch Resistance Test)
