WebThe hardness of the pencils is increased until one or both of the following defects mark. the coating: 1. Plastic deformation; a permanent indentation in the paint surface without cohesive fracture. 2. Cohesive fracture; the presence of a visible scratch or rupture in the surface of the paint film, material. WebSep 23, 2014 · This can be done using a spectrophotometer. Adhesion testing is another one; the paint needs to stick to the substrate. There are a number of test methods for this, including the peel test (ASTM D3359) and the pull-off test (ASTM D4541). You might also need to measure paint thickness or hardness.
