ABSTRACT:
Powder coating compositions having improved mar and scratch resistance are disclosed. The coatings generally comprise one or more particles that have been modified to render the particles more surface active. The improved resistance is achieved without affecting the appearance or mechanical performance of the coatings. Methods for using the coatings, and the substrates coated therewith, are also disclosed.
