High quality Autoatic Scratch Tester

The strength, hardness and adhesion of the coating film are important physical properties of the film, and its size directly affects the important performance of the film, such as: wear resistance; wear resistance; scratch resistance; impact resistance and retention of the film and cleaning difficulty. Therefore, the strength and hardness of the film are necessary indicators to evaluate the performance of the coating. Using this instrument can conveniently and comprehensively evaluate the physical properties of film strength, hardness, adhesion, etc., so the purpose of this instrument is to characterize the strength, hardness and adhesion of the coating by the size of the penetration resistance of the paint film sample coating when it is scratched by a scriber.
