Abstract

Abstract: UV-curable epoxy acrylates were prepared by reacting epoxy resin with acrylic acid in the presence of quaternary ammonium salt. The effects of temperature, inhibitors,catalysts and others on the reaction have been examined. The mechanism and the kinetics are discussed. The UV-curing was determined by IR spectra. In the presence of 0.6%～1.2% quaternary ammonium salt at 90～110℃, after 4.5～8 hours, the conversion of the epoxy group achieved over 97% and the paint obtained could be cured fast by UV-light irradiation.

Key words: epoxy acrylate, quaternary ammonium salt, UV-curing, coating
