摘要： A method for a low temperature cure for a coating composition comprising: applying to a substrate a low temperature curing coating composition consisting essentially of a film forming component consisting essentially of a non-carbamate functional polymeric component selected from the group consisting of polyester, silicone modified polyester, polyurethane, acrylic, alkyd, epoxy, polyamide, phenolic and polysilane polymers and mixtures thereof; a crosslinking component to crosslink the non-carbamate functional polymeric component; a catalyst selected from the group consisting of Lewis acids, perflouracetic acid, methane sulfonic acid catalyst and mixtures thereof; and additives selected from the group consisting of solvents, flow control agents, pigments, flexibilizing resins, surfactants, waxes, wetting agents, plasticizers, anti-oxidants, UV light absorbers, and a mixture thereof, and subjecting the coated substrate to a cure temperature of between 280° F. and 450° F., for a time sufficient to cure the coating.
