ABSTRACT:
Aqueous two-component systems based on epoxide resins and diamines, containing water in an amount of 1 to 20 wt. % which are prepared by mixing: (a) as a curing agent, a (cyclo)aliphatic di-primary-diamine having 2 to 12 carbon atoms, in homogeneous solution with 2-40 wt. % water, (b) as an epoxide resin component, (i) a polyglycide compound of a bisphenol, an aliphatic polyol, a polyether polyol, a dicarboxylic acid, or a mixture of these polyglycide compounds and (ii) a polyacrylate of a polyol or a polyether polyol, have a low water content, are cold-curable, yield elastic coatings with good solvent resistance, and may be applied in thick layers and with a high filler content. The systems may be used for coating inorganic and organic materials.
