Analysis of Coatings Appearance and Durability Testing Induced Surface Defects Using Image Capture/Processing/Analysis

There are no established and accepted techniques available for accurate characterization appearance changes brought about by scratch and mar damage. Scratch and mar resistance is related to the ability of a coating in resisting deformation. The appearance change is brought about by surface roughening which in turn leads to a reduction in gloss and reflectivity. This paper focuses on the measurement of the appearance of coating by image analysis and gloss measurement.
