A non-gelled amine-epoxide reaction product and acid addition acid addition salts thereof where the product is obtained by co-reacting;n 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 (1): nNR³R⁴(CH₂) n NH₂ (1) nin 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. |
