Patent ID: 7714069

Claim:
A method of producing an adherent coating on a resinous substrate, said method comprising: (a) mixing a crosslinkable component with a crosslinking component of a coating composition to form a pot mix, said crosslinkable component comprising a polymeric mix containing at least one crosslinkable copolymer polymerized from a monomer mixture comprising one or more ethylenically unsaturated monomers having on average 1 to 10 hydroxyl groups and a saturated hydrocarbon polymer wherein said monomer mixture comprises in the range of from 70 parts to 99 parts of said ethylenically unsaturated monomers and 1 part to 30 parts of said saturated hydrocarbon polymer, all in parts by weight based on 100 parts by weight of said crosslinkable component; and crosslinking component comprising: R 1 —(R 2 —NCO) n wherein R 1 is a substituted or unsubstituted cycloaliphatic group containing 3 to 20 carbon atoms in the ring, R 2 is independently selected from a direct bond, a straight aliphatic group or branched aliphatic group, wherein said aliphatic group has from 1 to 6 carbon atoms, and wherein n ranges from 2 to 10; (b) applying a layer of said pot mix over said resinous substrate; and (c) curing said coating on said resinous substrate.
