    摘要: Discussed are heat-curable epoxy resin compositions containing at least one epoxy resin with, on average, more than one epoxide group per molecule, at least one curing agent for epoxy resins, which is activated by an increased temperature and at least one terminally blocked polyurethane prepolymer. Said epoxy resin compositions are particularly suitable for use as one-component, heat-curable adhesives and are characterized by excellent mechanical properties, high glass transition temperatures and high impact resistance.

    摘要: The present invention concerns low-odor, low-viscosity hardeners for epoxy resins, including an amine with at least one amino group of formula (I) and an amine with at least one amino group of formula (II), wherein the amino groups of formulas (I) and (II) are present in a particular ratio. These hardeners harden quickly with epoxy resins and without blushing to form films of high hardness and good resistance. They are especially suitable for low-emission coatings.
