Abstract
Methods of reducing the release of volatile organic compounds (VOCs) into the Earth's atmosphere during coating operations are provided, as well as a coating composition comprising a carrier and one or more fluorocopolymers. The carrier comprises VOC compounds and the one or more fluorocopolymers is produced by copolymerization of (1) a first monomer selected from the group consisting of hydrofluoroalkenes, (2) a second monomer comprising vinyl ester(s), and (3) a third monomer comprising vinyl ether(s), wherein at least a portion of the vinyl ether monomer is a hydroxyl group-containing vinyl ether, and wherein the one or more fluorocopolymers comprise at least about 70% by weight of the coating composition and the VOC portion of the carrier is not greater than about 30% by weight of the coating composition.
