摘要： Methods in which toughness improvers based on terminally blocked polyurethane prepolymers are used to increase the maximum linear expansion of single component heat-curing epoxy resin compositions, in particular for joining substrates having different thermal expansion coefficients, in particular in the framework of transport agents or white goods.

摘要： 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.

摘要： A reinforcing element for reinforcing structural elements including at least one channel on an outer side. The outer side forms a shoulder next to the channel. Furthermore, the reinforcing element is provided for forming an open system in terms of an adhesion of the reinforcing element in the structural element, wherein, in a use state of the reinforcing element in the structural element, a space is formed between the shoulder of the reinforcing element and the structural element, which is open relative to an adjacent cavity of the structural element.

摘要： 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.
