Coating Impact & Flexibility Tester

Coating Flexibility Testers

For a coating to perform properly during use, the paint must have the proper amount of flexibility to withstand cracking under stress. A common test is bending a coated panel over a cylindrical or conical shaped bar. A mandrel bender is commonly used to test for paint flexibility. A cupping tester is another coating flexibility tester that slowly pushes a round punch through a coated panel until cracking occurs in the paint film. The degree of bending or deformation of the coated surface is measured to assess the coating flexibility.

Impact Tester

The Impact Tester is a widely used device for the coating and plastic industries. In both industries impact resistance is measured by a falling weight from a controlled distance. For plastic materials the force is increased until structural failure occurs. In the case of a coated surface, failure will appear as a crack in the paint film. The impact tester creates a deformation in the surface that can also be used to measure a coating’s flexibility. BYK-Gardner offers a wide variety of models and accessories to comply with ASTM and ISO methods related to a resistance tester.
