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. |
