  • Patent number: 10273326
    Abstract: What is described is a polymer which is a polyurethane polymer having blocked isocyanate groups or a reaction product of said polyurethane polymer with at least one epoxy resin, where the polyurethane polymer having blocked isocyanate groups is an addition product formed from at least one polyisocyanate and at least one polyester polyol, wherein the isocyanate groups of the addition product have been blocked by reaction with at least one aromatic compound having at least one hydroxyl group. Such a polymer is suitable as an impact modifier in epoxy resin compositions, especially when they are used as adhesives or structural foams. The polymer improves the corrosion resistance and vertical expansion of the epoxy resin composition.

  • Publication number: 20190002626
    Abstract: Heat-curing epoxy resin compositions are characterized by high impact strength, good storage stability, and a low curing temperature. The epoxy resin compositions are suitable for use as a construction shell adhesive and for producing structural foams. They can already be cured in so-called bottom-baking conditions. Furthermore, it has been found that the use of an accelerator of the formula (Ia) or (Ib) results in an increase of the impact strength of heat-curing epoxy resin compositions.
