Abstract
The present invention relates to a powder coating composition including: an addition polymer including epoxy functional groups: a carboxylic acid functional crosslinker: and a blocked isocyanate functional crosslinker. The addition polymer is obtained from components including at least one epoxy functional ethylenically unsaturated monomer. The components include an amount of the at least one epoxy functional ethylenically unsaturated monomer within a range of greater than 10 weight % and less than 22 weight %. based on the components that form the addition polymer.
