Top Coat Composition

Abstract

Methods for forming top coats include spray-applying a waterborne top coat composition on the substrate to form a top coat layer, wherein the waterborne top coat composition comprises water, pigment(s) and resin solids, the resin solids comprising about 60 to 100 wt. % of binder solids and 0 to about 40 wt. % of crosslinker solids, the binder solids comprising about 1 to about 40 wt. % of a urethanized polyester/(meth)acryl copolymer hybrid binder having a hydroxyl number of about 30 to about 200 mg KOH/g and a carboxyl number of about 8 to about 50 mg KOH/g, and about 60 to about 99 wt. % of one or more additional binders, the sum of the respective wt. % in each case equaling 100 wt. %; and curing the top coat layer to form a cured top coat.
