Abstract:
An adhesive composition consisting essentially of 10-90 weight percent ester monomer, about 2-85 weight percent polymeric elastomer, about 0.02-10 weight percent initiator, and about 0.005-7 weight percent of a retarding additive, said retarding additive being selected from the group consisting or non-protonic Lewis acids and zinc salts and mixtures thereof, said ester monomer being selected from the group consisting of methacrylate ester monomers, acrylate ester monomers and mixtures thereof, said retarding additive being present in an amount effective to (a) extend the open time of the adhesive composition at least five minutes or (b) reduce the peak exotherm temperature of the adhesive composition at least 15.degree.
