Patent ID: 8096190

Claim:
A method of constructing multiple pull plates on a coating for testing the adherence of the coating to a substrate comprising: applying the coating to a surface of the substrate to form a test piece; constructing a mold assembly having multiple mold cavities for forming multiple pulling elements, said pulling elements shaped to allow a pulling force to be applied thereto; applying the mold assembly to the test piece at an interface, wherein at least one wall of the multiple mold cavities is formed by the test piece; filling the multiple cavities with a liquid material to form the multiple pulling elements, wherein said liquid material is a polymerizable material; bonding the pulling elements to the test piece by polymerizing the liquid material in the multiple cavities; and removing the mold from the test piece to provide access to the pulling elements; and perform a series of adherence tests on the test piece by applying forces to each of the pulling elements to determine the adherence of the coating to the substrate.
