The design principle is that a freely falling object impacts the coating and its substrate, causing deformation, cracking, and peeling, to evaluate the impact resistance of the coating. It can also test the impact resistance and flexibility of the material itself;

This impact tester has a wide range for impact resistance testing and is suitable for many types of coatings and substrates, such as paints, varnishes, high viscosity plastic coatings, and laminated coatings. It can also be used in quality management standards for impact resistance testing and penetration testing in construction, such as metal, plastic, resin, fiberglass, board, plywood, etc

Load punch（Multiple weights）The paint sample on the impact test piece can be evaluated based on its dispersion or cracking condition when dropped from a fixed height. Multiple types of load punches and platforms can be used for various tests.

This instrument is particularly suitable for various comprehensive testing institutions, laboratories, large enterprise groups, scientific research institutions, and units that require compliance with multiple impact standards. The instrument almost covers relevant impact standards and can achieve the function of one machine for multiple uses.
