The MCJ-01A Rub Tester from Labthink Instruments Co. is designed to test the abrasion resistance of surface coating layers on printed materials. It can effectively analyze problems like poor abrasion resistance, ink layer falling off, low printability, and hardness of coatings. The instrument precisely follows standard test method requirements and is controlled by a microcomputer with a convenient interface. It is used to test the abrasion resistance of ink layers on printed papers and photosensitive coating layers on boards.
