A coating composition is substantially free from chromate and comprises a resin, a metal salt, and an interference pigment. The interference pigment includes mica which has a solar reflective coating disposed thereon. A reflective coating system comprises a cured film formed from the coating composition disposed on a substrate. The cured film has a transparency of at least 75%, as measured according to ASTM 1746. In addition, the cured film has a solar reflectivity of at least 55%, as measured according to ASTM E 1918 and ASTM E 903. The cured film has excellent corrosion resistance properties and adhesion to the substrate.

An acrylic resin and method of forming the acrylic resin for use in fluorocarbon coating compositions are disclosed. The fluorocarbon coating composition generally comprises a fluorocarbon resin, a cross-linking agent, and the acrylic resin. The acrylic resin comprises the reaction product of (1) at least one non-functional acrylic monomer, (2) at least one epoxy functional acrylic monomer having an epoxy group, and (3) at least one functional acrylic monomer different than (2). At least one amino compound having a cyclic, heterocyclic, alkyl, or heteroalkyl structure substituted with a primary or secondary amine group is reacted with the epoxy functional acrylic monomer (2) such that the primary or secondary amine opens the epoxy group to obtain the acrylic resin having amine functionality and hydroxyl functionality.

A hyperdispersant for use in a fluorocarbon coating composition is disclosed. The fluorocarbon coating composition generally comprises a fluorocarbon resin, a binder resin, a cross-linking agent, and the hyperdispersant. The hyperdispersant comprises the reaction product of a polyglycidyl oligomer and at least one amino compound. The polyglycidyl oligomer comprises a carbon chain having from 1 to 25 carbon atoms with at least one of an internal ether linkage and an internal ester linkage and comprises a plurality of epoxy groups. The at least one amino compound has a cyclic, heterocyclic, alkyl, or heteroalkyl structure substituted with at least one primary or secondary amine group for reacting with and opening at least one of the epoxy groups.

A coil coating composition producing a coil coating with excellent properties at a lower peak metal temperature includes (a) a first, branched polyester with an hydroxyl number of at least about 80 mg KOH/g, (b) a second, essentially linear polyester with an hydroxyl number of at least about 44 mg KOH/g, and (c) a crosslinking agent. The branched polyester is prepared by condensation of a polyol component consisting essentially of a flexibilizing diol, a branched diol, and, optionally, a polyol having at least three hydroxyl groups and a polyacid component consisting essentially of one or more aromatic or cycloaliphatic dicarboxylic acids and polymerizable anhydrides and esters thereof and, optionally, a polyacid having at least three carboxylic acid groups or poymerizable anhydrides or esters thereof, wherein at least one of the polyol having at least three hydroxyl groups and the polyacid having at least three carboxyl groups or an anhydride or methyl ester thereof is included. The essentially linear polyester is prepared by condensation of a polyol component consisting essentially of a flexibilizing diol and a branched diol and a polyacid component consisting essentially of one or more aromatic or cycloaliphatic dicarboxylic acids and polymerizable anhydrides and esters thereof. The branched diols of the first and second polyesters are independently selected from the group consisting of 2-methyl-1,3-propanediol, 2,2,4-trimethyl-1,3-pentanediol, 2-ethyl-2-butyl-1,3-propanediol, propylene glycol, neopentyl glycol, and combinations thereof.
