Abstract: A method of producing a hem flange bond wherein the method uses a one-component thermosetting epoxy resin composition including 20-60% by weight of at least one epoxy resin A, a latent curing agent for epoxy resins B, 10-40% by weight of at least one toughness improver D, and 4-12% by weight of a room temperature solid, crystalline polyester polyol PP. This enables compositions that are suitable for spray application and are not expressed from the hem flange in the crimping operation.

Abstract: A thermosetting epoxy resin composition including, as curing agent, a dihydrazide selected from the group consisting of glutaric dihydrazide, adipic dihydrazide and pimelic dihydrazide, in combination with a specific urea accelerator, which features good storage stability and a low curing temperature. The epoxy resin composition is especially suitable for use as bodywork adhesive.

Abstract: A one-component thermosetting epoxy resin compositions that feature good storage stability. The epoxy resin compositions are especially suitable for use as bodywork adhesive and for production of structural foams.

Abstract: 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.

Abstract: A system including two pre-fixed substrates, wherein a first substrate and a second substrate. Each of the substrates has an opening in an overlap region, and an adhesive is arranged between the overlap regions, wherein the adhesive connects the two substrates together and is arranged at least partly in the openings. The adhesive is locally cured in the region of the openings. A cured sub-region of the adhesive extends from the first opening into the second opening, and a second sub-region of the adhesive is not cured.

Abstract: A sheet-like textile is used for a controlled expansion of an expansion element on a structural element in a vehicle body. The sheet-like textile is covered with an expandable material on both sides. The expansion of the expansion element in a direction perpendicular to the sheet-like textile is at least 15% greater than what it would be for an expansion element without a sheet-like textile.

Abstract: A method of bonding two shaped bodies S1 and S2 including the steps of: a) providing shaped body S1; b) arranging shaped body S2 wherein shaped body S1, forming cavity between two shaped bodies, c) introducing one-component thermosetting epoxy resin compositions into cavity, wherein one-component thermosetting epoxy resin composition is one-component thermosetting epoxy resin composition including: at least one epoxy resin A having average of more than one epoxy group per molecule; at least one curing agent B for epoxy resins activated by elevated temperature; at least one polyester polyol PP obtainable by reaction of at least one diol having structure HO—(CH2)x?—OH the value of x?=2-10, and —at least one dicarboxylic acid having structure HOOC—(CH2)y?—COOH and derivatives of dicarboxylic acid, value of y?=8-18, and wherein proportion of polyester polyol PP is 1.5% to 20% by weight, based on total weight of one-component thermosetting epoxy resin composition.

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.
