| abstract |
A non-gelled amine-epoxide reaction product and acid addition salts thereof which can be used in coating compositions suitable for application to a substrate by electrodeposition, where the product is obtained by co-reacting (A) a secondary amine NHR1R2, wherein R1 and R2 the same or different are C2 or C3 hydroxyalkyl groups, (B) a polyepoxide, (C) optionally a polyoxyalkylene polyamine, (D) a product of the reaction between an epoxide with at least two epoxy groups and which contains less than 40% by weight of aromatic groups, and an amine of formula NR3R4(CH2)nNH2 in which n is from 2 to 6, and where R3 and R4, the same or different are methyl or ethyl, and optionally (E) a monoepoxide, the components of product (D) being chosen so that the non-gelled amine epoxide reaction product is a liquid at temperature above -5°C. |
