  • Patent number: 6653412
    Abstract: A curing agent for epoxy resins comprises: a) a reaction product of at least one polyalkylene polyether monoamine and/or polyamine with a polyepoxide and optionally, a monoepoxide to obtain an epoxide group-containing precursor, the precursor further reacted with a primary monoamine and/or a primary or secondary polyamine in at least a 10% molar excess relative to the epoxide groups of the precursor, the reaction product being substantially free of non-reacted amines; b) an amine-terminated adduct of an epoxy resin and a primary monoamine and/or a primary or secondary polyamine being substantially free of non-reacted amines; and c) an amine-terminated adduct of an epoxide group-containing reactive thinning agent and a primary monoamine and/or a primary or secondary polyamine being substantially free of non-reacted amines, wherein the epoxy resin of component b) and epoxide group-containing reactive thinning agent of c) are added to the epoxide group-containing precursor of component a) before the reaction

  • Patent number: 6566423
    Abstract: Novel cold-curing mixtures comprising epoxide compounds, curing agents, additives and optionally further auxiliary and filler materials, which have low irritant potential, which are free of solvents and are self-levelling and which, in the cured state, are colorfast and have a surface which, in terms of optical and tactile properties, is faultless.
