Paint Adhesion Testing Instrument

The paint adhesion tester uses mechanical force to peel the coating from the substrate, measuring the bonding strength between the coating and the substrate. It is used to evaluate coating durability and test coating quality in industries such as automotive and construction.
Selection
When selecting, consider the substrate type and coating thickness to match the instrument's measurement range, ensure the testing standards comply with industry specifications, check that the blade specifications are compatible with the coating hardness, and verify the validity of the instrument's calibration certificate.
