Buchholz Hardness

The BGD 510 Buchholz Indentation Tester provides a reliable method for evaluating the indentation resistance of plastic-deformable coatings. A beveled disc with a sharp edge is applied to the test surface with a constant 500 g load supplied by a stainless steel block After 30 seconds, the length of the indentation left on the coating is measured using a 20x magnification illuminated microscope. The length of the indentation is inversely proportional to the coating hardness
