Electric Paint Film Circular Scratch Tester

The electric paint film circular scribing tester drives a scribing needle to draw circles on the surface of the paint film via an electric motor, and evaluates the adhesion level based on the degree of paint film peeling. It is used to test the bonding strength between coatings such as paints, inks, and substrates, helping to assess coating durability and construction quality.
Selection
When selecting, consider that the needle load range should cover the thickness of the coating to be tested, and the rotation speed must meet the requirements of the testing standards. The instrument should be equipped with a scratch trajectory observation device, and its structure should be sturdy to ensure test repeatability. Priority should be given to products that comply with national standards such as GB/T 1720.
