Abstract
Abstract Described is an aqueous chip resistant coating composition exhibiting a viscosity of at least 5,000 centipoise, preferably containing binders with a high molecular weight, preferably at least 20,000. Although these coatings may be applied to a variety of substrates, for coating electrocoated substrates the following eight binders are particularly preferred: ethylene vinyl acetate copolymer, carboxylated ethylene vinyl acetate, epoxy functional acrylic resin, carboxylated styrene-butadiene resin, carboxylated acrylic, hydroxy functional acrylic, self-crosslinking acrylic; and carboxylated PVC acrylic. Generally, it is preferred to apply the chip resistant coating via an airless spray and then heat curing the coating.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
64 words
A method of coating a substrate comprising the steps of: (a) electrodepositing an organic coating onto a substrate; and then (b) depositing a chip resistant coating thereon, and (c) curing the chip resistant coating; wherein the chip resistant coating is comprised of: film forming latex binder; and filler mixed with the binder to form a composition having a viscosity of at least 5,000 centipoise.
Claim 2
Independent Claim
64 words
A method of coating a substrate comprising the steps of: (a) electrodepositing an organic coating onto a substrate; and then (b) depositing a chip resistant coating thereon, and (c) curing the chip resistant coating; wherein the chip resistant coating is comprised of: film forming latex binder; and filler mixed with the binder to form a composition having a viscosity of at least 5,000 centipoise.
