Paint film circle Tester

The paint film circle-drawing tester uses a metal stylus to draw circles at a constant speed on the surface of the paint film, determining the adhesion level based on whether the scratch exposes the substrate. It is used to evaluate the bonding strength between the coating and the substrate and is suitable for quality control in industries such as coatings and plastics.
Selection
When selecting, consider the scratch load range required by the testing standards, and check whether the instrument has the function of graded loading with weights. Confirm the vertical accuracy between the scratch needle fixture and the sample stage, which should include standard scratch needles of different specifications. Check whether the circular trajectory is smooth and whether the rotational speed complies with the standard specifications.
