Silicate layers such as mica or talc and graphite are particularly suitable as crack promoters, C. | 12-31-2009 |
20120055631 | HEAT CURABLE EPOXY RESIN COMPOSITION WITH WATER AS FOAMING AGENT - Heat-curable epoxy resin compositions and the use thereof, for example, in motor vehicle construction and sandwich panel construction, are disclosed. Exemplary heat-curable epoxy resin compositions include, in addition to epoxy resin components A1, optionally A2, a hardener component B, a carboxylic acid C and a hydroxyalkylamide or hydroxyalkylurea H, an accelerator E for activation of the conversion of components A1, A2 and B. The compositions and the structural foams produced therefrom are notable for high mechanical strength, high glass strength and good adhesion capacity on metallic and nonmetallic substrates, and it is possible at the same time to dispense with the use of toxic or inflammable blowing agents. | 03-08-2012 |
20130034736 | SHAPE MEMORY MATERIAL BASED ON A STRUCTURAL ADHESIVE - A composition, including at least one curable structural adhesive, and at least one thermoplastic elastomer, wherein the thermoplastic elastomer is present in the structural adhesive as penetrating polymer network. Such a composition constitutes a so-called shape memory material and is suitable for reinforcing cavities in structural components, such as, for example, in automobile bodies. | 02-07-2013 |
20130037213 | AMINO GROUP TERMINATED IMPACT STRENGTH MODIFIER AND USE THEREOF IN EPOXY RESIN COMPOSITIONS - The present disclosure relates to impact strength modifiers, the derivative products thereof, and the use thereof in producing two-component epoxy resin compositions. The disclosure in particular relates to amino group terminated impact strength modifiers prepared by reacting a polyurethane prepolymer having isocyanate groups, a primary diamine, and optionally at least one Michael acceptor. The two-component epoxy resin compositions thus formulated are characterized by a great increase in impact strength while retaining an acceptable tensile shear strength. The impact strength modifiers according to the disclosure and the epoxy resin compositions comprising same are in particular suitable for vehicle manufacturing. | 02-14-2013 |
20130230726 | TWO-COMPONENT STRUCTURAL ADHESIVE WHICH IS IMPACT RESISTANT AT ROOM TEMPERATURE - The disclosure relates to the field of two-component epoxy resin compositions and to the use thereof as a repair adhesive, in particular in vehicle manufacturing. The two-component epoxy resin compositions according to the disclosure contain a curing component K2, which comprises between 1 and 10 wt. % of an amino group-terminated polyamide B, together with an epoxy resin component K1. The compositions show that the impact resistance is highly increased while an acceptable sheer strength is simultaneously retained. | 09-05-2013 |
