Low bake temperature curable coating compositions and processes for producing coatings at low bake temperatures

A process for producing a coating on a substrate comprising:

• (a) mixing a cross-linkable component, a crosslinking component and a low bake temperature control agent of a low bake temperature curable coating composition to form a pot-mix, said crosslinkable component comprising an acid functional acrylic copolymer polymerized from a monomer mixture comprising about 2 weight percent to about 12 weight percent of carboxylic acid group containing monomer based on total weight of the acid functional acrylic copolymer, and wherein said low bake temperature control agent comprises a rheology component chosen from an amorphous silica, a clay, or a combination thereof, the rheology component present in an amount of about 0.1 weight percent to about 10 weight percent, and about 0.1 weight percent to about 10 weight percent of polyurea, said percentages based on total weight of the crosslinkable and crosslinking components;
• (b) applying a layer of said pot-mix over said substrate;
• and
• (c) curing said layer at low bake temperature into said coating on said substrate.
