Abstract
An epoxy functional acrylic resin having a Tof greater than 85° C. and a calculated solubility parameter from about 9.20 to about 9.30 (cal/cm), powder coating compositions including the same and coated substrates coated with the powder coating composition is described. The resin includes, as copolymerized monomers, from about 10 wt. % to about 40 wt. % of one or more epoxy functional unsaturated monomers; from about 10 wt. % to about 20 wt. % of one or more hydrophobic acrylic monomers, and from greater than 50 wt. % to about 75 wt. % of at least one nonionic copolymer that is different from the hydrophobic acrylic monomers ii), each monomer wt. % based on the total weight of copolymerized monomers in the resin.
