WATER-DILUTABLE BONDING AGENTS CONTAINING LATENT PRIMARY AMINO GROUPS FOR CATIONIC ELECTROPHORETIC ENAMELLING AND A PROCESS FOR THEIR PRODUCTION

摘要

Water-dilutable bonding agents containing latent primary amino groups for cationic electrophoretic enamelling. To produce the bonding agent an epoxy resin is converted with a polyamine which contains, in addition to a sterically-hindered primary amino group, at least one primary amino group which is blocked by conversion with a ketone or aldehyde, and if applicable further primary or secondary amines.
