Varnish Friction Resistance Tester

The varnish abrasion tester simulates daily wear by moving a friction head with a fixed load back and forth on the coating surface. It is used to determine the scratch resistance of varnish coatings and verify the durability of coatings in areas such as wood lacquer and automotive coatings.
Selection
When selecting, pay attention to matching the load range with actual usage conditions, and ensure that the material of the friction head corresponds to the testing standards. The stroke length should cover common wear areas, and the counting device must accurately record the number of friction cycles. The equipment structure should ensure testing stability.
