Abstract
Described are in-mold coated products such as vehicular components, in-mold coating methods, and in-mold coating compositions, involving the use of aqueous acrylic copolymer dispersions, desirably self-crosslinking.
Claims16
A method of manufacturing a coating for a vehicular component, comprising the steps of:
- providing a mold for making a vehicular component, the mold having a mold surface;
- coating the mold surface with an in-mold coating composition, said in-mold coating composition comprising:
- a non-polyol aqueous copolymerisate dispersion comprised of acrylic esters and styrene;
- a microspersion wax additive;
- a flattening agent;
- water;
- n-butanol;
- a thickening agent;
- and a flow additive;
- passing a polyurethane composition into the mold and into contact with the in-mold coating composition;
- and
- causing the in-mold coating composition and polyurethane composition to cure, so as to form the coating for the vehicular component.

A method of manufacturing a coated, molded polyurethane elastomer product, comprising the steps of:
- providing a mold for making the product, the mold having a mold surface;
- coating the mold surface with an in-mold coating composition, said in-mold coating composition comprising:
- a non-polyol aqueous copolymerisate dispersion comprised of acrylic esters and styrene;
- a microspersion wax additive;
- a flattening agent;
- water;
- n-butanol;
- a thickening agent;
- and a flow additive, wherein the weight ratio of the non-polyol aqueous copolymerisate dispersion to water is 2.4, and wherein the weight ratio of the non-polyol aqueous copolymerisate dispersion to the microspersion wax additive is 26.5;
- passing a polyurethane elastomer composition into the mold and into contact with the in-mold coating composition;
- and
- causing the in-mold coating composition and polyurethane elastomer composition to cure, so as to form a coated, molded polyurethane elastomer product.
