ABSTRACT

Coatings are inherent to many technologies, from paint systems to electronics manufacturing [1-3]. One of the parameters that needs to be known is the adhe­ sion, or resistance to fracture, of a coating to a substrate or to another coating. In general, it is difficult to quantify this adhesion. Many qualitative methods are available, such as the crosshatch-peel test and the x-hatch test for paints. Quanti­ tative methods include instrumented peel tests, double cantilever beam methods, and blister tests. These techniques require special sample preparations, which makes them difficult to apply to paint adhesion.
