Mar Resistance Tester

A mar is a blemish on the surface of a coating, extending over a particular area and visible due to differences in the light-reflection properties of the affected area compared to adjacent areas. The mar resistance test for coatings is very similar to the scratch resistance test. However, this test uses an arc-shaped (loop or ring-shaped) stylus to assess the mar resistance of a single coating layer, paint, varnish, related product, or the upper layer of a multi-coat system
