POWDER COATING COMPOSITIONS COMPRISING A COPOLYMER OF A GLYCIDYL ACRYLATE, A MONOHYDROXY LATE AND OLEFINICALLY UNSATURATED MONOMERS

摘要

Powder coating compositions are disclosed which comprises a copolymer of about 5 to about 20 weight percent of a glycidyl acrylate, about 2 to about 10 weight percent of a C5 - C7 monohydroxy acrylate, and about 70 to about 93 weight percent of other olefinically unsaturated monomers in combination with an anhydride crosslinking agent. Other materials such as pigments, catalysts, flow control agents and plasticizers are used in individual compositions. Such compositions constitute an improvement over heretofore disclosed coating materials of otherwise similar composition which do not include the hydroxy acrylate component of the copolymer.
