Radiation-curing aqueous coatings providing a nonadherent surface

摘要

A radiation-curable aqueous emulsion coating composition which cures to provide a nonadherent surface is provided by emulsifying droplets of liquid alkyl hydrogen polysiloxane in water, the water having dispersed therein a radiation-curable polyethylenically unsaturated tertiary amine, such as an amine polyacrylate, at least partially neutralized with a solubilizing acid. The aqueous emulsion preferably includes a photosensitizer rendering the composition curable with ultraviolet light.
