© 2005 by NACE International. A new progressive load test is introduced to study the scratch behavior of a set of model UV-cured epoxy acrylate coatings. A custom-built scratch tester, capable of controlling imposed load and scratching rate, was employed. The model coating systems possess systematic variations in crosslink density. Microscopy tools were also utilized to determine the mode(s) of failure on the coating surfaces. Correlation is made between the coating resistance against surface damage and material parameters, such as modulus, ductility and adhesive strength to the substrate. The usefulness of the quantitative test method for improving coatings against scratch and wear is discussed.
