Claims16
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 at least a portion of the mold surface with an in-mold coating composition, said in-mold coating composition comprising a non-polyol aqueous copolymerisate dispersion comprising an acrylic ester;
- a microspersion wax additive;
- a flattening agent;
- a solvent;
- and a flow additive;
- passing a polyurethane elastomer composition into the mold and into contact with at least a portion of 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.

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 at least a portion of 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 solvent, wherein the weight ratio of the non-polyol aqueous copolymerisate dispersion to the solvent is approximately 2.4;
- passing a polyurethane elastomer composition into the mold and into contact with at least a portion of 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.
