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.

Abstract: Waterborne top coat compositions, processes for preparing such compositions, and methods for forming top coats on substrates are provided. In an embodiment, a waterborne top coat composition includes water, pigment(s) and resin solids. The resin solids comprise 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. %.

Abstract: Waterborne top coat compositions, processes for preparing such compositions, and methods for forming top coats on substrates are provided. In an embodiment, a waterborne top coat composition includes water, pigment(s) and resin solids. The resin solids comprise 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 an acrylic/(meth)acryl copolymer hybrid binder, 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. %.
