Scratch Scuff Mar Finish Tester

SCHAP’s Scratch Scuff Mar Finish Tester is used to evaluate the propensity of materials such as automotive paints, coatings & finishes to scratch, scuff or mar.

The Scratch Scuff Mar Finish Tester is designed to determine how well a material surface can withstand scuffing and marring per General Motors specification GM-9150P.  The test fixture locates the test sample while the operator loads the paper clip with a calibrated weight.
