Scratch Resistance Tester KK-02，ASTM D7027 Abrasion and scratch edge durability tester
The KK-02 Scratch Resistance Tester is intended for medium-load scratch resistance evaluation of plastics, films, coatings, and automotive materials. Using a progressive vertical load and horizontal scratch motion, you can accurately measure scratch characteristics and surface damage behavior for material comparison and quality control.
Application
Scratch resistance testing of plastic and polymer materials
Surface performance evaluation of coatings and painted components
Scratch testing of automotive interior and trim parts
Durability assessment of packaging and electronic enclosure materials
Routine quality control and laboratory material evaluation
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)
