Abstract
Official abstract text for this publication.
A polymer useful in coating compositions is described. The polymer is preferably an unsaturated polyurethane polymer, which preferably has an iodine value of at least 10. The polymer may be combined with one or more liquid carriers to form a liquid coating composition useful in coating a variety of substrates, including planar metal substrates.
First claim
Opening claim text (preview).
What is claimed is: 1 - 20 . (canceled) 21 . A coated article, comprising: a planar metal substrate with a coating disposed thereon, the coating derived from a coating composition comprising: at least 5 wt % of an unsaturated polyurethane polymer that includes one or more aliphatic carbon-carbon double bonds with heat of hydrogenation of at least about −28.25 kcal/mol; and a liquid carrier. 22 . The article of claim 1 , wherein the one or more aliphatic carbon-carbon double bonds have heat of hydrogenation of at least about −33.13 kcal/mol. 23 . The article of claim 1 , wherein the unsaturated polyurethane polymer is self-crosslinkable. 24 . The article of claim 1 , wherein the unsaturated polyurethane polymer includes one or more segments formed from an unsaturated polybutadiene. 25 . The article of claim 1 , wherein the unsaturated polyurethane polymer includes one or more ether linkages. 26 . The article of claim 1 , wherein the coating composition comprises an aqueous dispersion of the polyurethane polymer.
