Abstract
We recently reported on various techniques we have developed for accurate characterization appearance changes brought about by scratch and mar damage. Scratch and mar resistance is related to the ability of a coating to resist deformation. The appearance change is brought about by the scratches and by roughening, which in turn leads to a reduction in gloss and reflectivity. Marring can be minimized by the appropriate use of the wipe material employed. This paper reports on three common wipes used by the automotive industry and focuses on the measurement of the appearance of coating by image analysis.
