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.

Thermosetting epoxy resin composition having low curing temperature and good storage stability

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.

Heat-curing epoxy resin composition having high storage stability

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.

Reinforcing element, system of a reinforced structural element and method for reinforcing a structural element

A method of bonding two shaped bodies Sand Sincluding the steps of: a) providing shaped body S; b) arranging shaped body Swherein shaped body S, 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&#x2014;(CH)&#x2014;OH the value of x'=2-10, and &#x2014;at least one dicarboxylic acid having structure HOOC&#x2014;(CH)&#x2014;COOH and derivatives of dicarboxylic acid, value of y&#x2032;=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.

Method for connecting molded bodies by injecting a single-component heat-curing epoxy resin composition into cavities

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.
