A method for obtaining a phenolic epoxy coating composition acrylated for water dilutable and storage stable

摘要

A storage-stable water-dilutable coating composition for use on the interior of food containers comprises a polymer obtained by polymerising a plurality of acrylic monomers including an acidic monomer in the presence of a high molecular weight epoxy resin, a phenolic resin, and a free radical initiator dissolved in a water miscible solvent. The resulting polymer solution is rendered water dilutable by the addition of ammonia or an aqueous amine which neutralizes the carboxyl functionality of the acrylic monomers.
