  • Patent number: 11198754
    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.

  • Patent number: 11180199
    Abstract: A system of connected body elements for a motor vehicle includes a first body element and a second body element. The first body element has at least one duct on a surface, wherein a shoulder is formed next to the duct. The system furthermore includes an adhesive which is arranged at least partially in the duct and at least partially on the shoulder and adhesively bonds the first body element to the second body element. A connection region, directly adjoining the shoulder, of the surface of the first body element is free here from adhesive. A first space between shoulder and second body element and a second space between connection region and second body element are open towards each other.

  • Publication number: 20190337278
    Abstract: An assembly comprising a substrate 1, a substrate 2 and heat curable adhesive, which is positioned between the substrates 1 and 2, wherein the heat curable adhesive is cured only in a portion of less than 50% of the entire surface covered by the heat curable adhesive. In this manner, the cured parts of the adhesive serve as “chemical screws” which sufficiently fix the substrates together during further processing steps, but do not involve complete curing of the adhesive.
