CA 1306566
PAT 36 094 June 22, 1987 Aqueous coating agent, a process for its preparation, and its use for coating of cans Abstract of the disclosure The invention relates to an aqueous coating agent, obtained from an epoxy resin, ethylenically unsaturated monomers, some of which contain carboxyl groups, a peroxide ini- tiator in a proportion of at least 2% by weight, rela- tive to the total weight of the monomers, a crosslinking agent, a neutralizing agent, organic solvents, and, if ap- propriate, further conventional additives, such as plas- ticizers, stabilizers, wetting agents, dispersion auxi- liaries, catalysts and pigments. The coating agent is based on a binder a) which is obtainable from A) 20 to 80% by weight of an epoxy resin having an average of more than one epoxy group Per molecule and having an average molecular weight of at least 500, B) 1 to 60% by weight of polyester polycarboxylic acids having an average molecular weight of 500 to 5,000 and having an acid number of 30 to 150, and C) 10 to 50% by weight of ethylenically unsaturated monomers, 10 to 50% by weight of the monomers containing carboxyl groups, where the sum of A), 33 and C) is 100% by weight, PAT 36 094 June 22, 1987 Aqueous coating agent, a process for its preparation, and its use for coating of cans Abstract of the disclosure The invention relates to an aqueous coating agent, obtained from an epoxy resin, ethylenically unsaturated monomers, some of which contain carboxyl groups, a peroxide ini- tiator in a proportion of at least 2% by weight, rela- tive to the total weight of the monomers, a crosslinking agent, a neutralizing agent, organic solvents, and, if ap- propriate, further conventional additives, such as plas- ticizers, stabilizers, wetting agents, dispersion auxi- liaries, catalysts and pigments.
