<p>1445370 Adducts of aminoamides; curing epoxy resins GENERAL MILLS CHEMICALS Inc 3 Dec 1973 [4 Dec 1972] 55827/73 Headings C3B and C3R Adducts, useful for curing epoxy resins, especially in aqueous compositions, are obtained by reacting an active acrylic compound (I) with an aminoamide of a mono- or polycarboxylic C 8-22 fatty acid or a C 1-8 alkyl ester thereof or an epoxidized C 8-22 fatty acid or a C 1-8 alkyl ester thereof. Examples of I are (meth)acrylic acid, methyl methacrylate, maleic acid or maleic anhydride. A typical aminoamide may be prepared by reacting an amine (R<SP>1</SP> is C 2-6 alkylene and p= 1-6 with a C 18 monocarboxylic acid. The aminoamide may have an amine number of 150-700. From 0À04-0À4 moles of I may be used per equivalent of amine in the aminoamide. Examples relate to the curing of aqueous compositions comprising diglycidyl ethers of bisphenol A having epoxide equivalents of 140-300. Conventional pigments, e.g. titania, may be present.</p> |
