Abstract
A composition including: —at least one silane group-containing polymer with a silicon content ranging from 0.6 to 2 wt. %, obtained by reacting at least one isocyanate group-containing polymer and at least one amino-, mercapto-, or hydroxysilane, —at least one liquid epoxy resin, and—at least one polyamine with at least three amine hydrogens which are reactive towards epoxy groups. The composition facilitates adhesives, coatings, or sealing compounds with a good storage stability, a fast curing time, even in the event of moisture or humidity, a surprisingly high degree of strength while having a high degree of elasticity, a high degree of resistance against further tearing, a high degree of resistance in particular against glycol/water mixtures, and a high degree of adhesion to many substrates. When used on metals such as steel or aluminum, the composition protects same against corrosion.
