1. A composition comprising
at least one polymer containing silane groups and having a silicon content in the range from 0.9 to 1.8% by weight, obtained from the reaction of at least one polymer containing isocyanate groups and at least one amino-silane, wherein the polymer containing isocyanate groups has been obtained from a reaction of at least one polyoxypropylene diol and at least one diisocyanate,
at least one liquid epoxy resin, and
at least one polyamine having at least three amine hydrogens reactive toward epoxy groups.
