With the S-20 Tungsten Carbide Tool, Taber's Shear/Scratch Tester can evaluate coating adhesion on a variety of materials. A precision cutting tool is attached to a balanced and calibrated scale beam, then placed on the specimen. As the turntable rotates the specimen, the cutting tool will shear the coating, allowing you to verify proper adhesion. By changing the load on the cutting tool, you can determine the point of failure.
