主权项

1. 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.
