ABSTRACT:
Additives comprising dispersed silica nanoparticles are disclosed. The silica nanoparticles are dispersed in an aminoplast, such as a modified aminoplast formed from the reaction between an aminoplast, a modifying component, and optionally a siloxane. The resulting additives can be added to coating compositions to provide improved mar and/or scratch resistance.
