ABSTRACT:
The present invention relates, in general, to tintable abrasion resistant coating compositions utilizing a tint additive and methods of making and using same. More particularly, but not by way of limitation, the tint additive is a polyethylene oxide polymer that is end capped on at least one “R” group with a silica containing compound.
