20100273005 | HEAT-CURING EPOXY RESIN COMPOSITION CONTAINING NON-AROMATIC UREAS AS ACCELERATOR - The present invention relates to heat-curing epoxy resin compositions, which 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. | 10-28-2010 |
20100280167 | IMPACT STRENGTH IMPROVING AGENT FOR EPOXY RESIN COMPOSITIONS - The present invention relates to a butadiene/acrylonitrile copolymer CTBN, modified by epoxy solid resin and terminated by carboxyl groups, the terminal epoxy groups thereof also having optionally been reacted. A polymer of this type is used in particular as an impact strength improving agent in epoxy resin compositions and has proven to be particularly advantageous for gluing on or of metal surfaces. It results in a significant reduction of the infiltration with corrosion, which in turn ensures a long-lived adhesive bond. | 11-04-2010 |
20110030893 | POLYURETHANE POLYMER BASED ON AN AMPHIPHILIC BLOCK COPOLYMER AND ITS USE AS IMPACT MODIFIER - Novel impact strength modifiers which are obtained by reaction of amphiphilic block copolymers. These impact strength modifiers are suitable in particular for use in heat-curing epoxy resin adhesives. In particular, combinations of different impact strength modifiers are also suitable for use in heat-curing epoxy resin adhesives. Also disclosed are methods of bonding heat-stable substrates. | 02-10-2011 |
20110039109 | ACTIVATOR FOR EPOXY RESIN COMPOSITIONS - Activators for heat-curing epoxy resin compositions, as well as use thereof in heat-curing epoxy resin compositions. These activators are distinguished by a good activation effect as well as good storage stability. | 02-17-2011 |
20110067813 | HEAT-CURING EPOXY RESIN COMPOSITION COMPRISING AN ACCELERATOR HAVING HETEROATOMS - A heat-curing epoxy resin composition that includes an epoxy resin, a curing agent, an accelerator, and an optional toughener. The epoxy resin compositions are suitable in particular for use as bodyshell adhesives and for preparation of structural foams. An accelerator of formula (I) results in increased impact strength the of heat-curing epoxy resin compositions. | 03-24-2011 |
20130020832 | REINFORCING ELEMENT FOR REFORCEMENT IN CAVITIES OF STRUCTURAL COMPONENTS - A reinforcing element for reinforcement in cavities of structural components including a substrate made of a plastics material, which is at least partially coated with a metal; and a foamable, thermosetting structural adhesive which is applied to the metal coating of the substrate; or a thermosetting structural adhesive which is applied to the metal coating of the substrate and is designed as a shape memory material. | 01-24-2013 |
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 |
20130253094 | ACTIVATOR FOR EPOXY RESIN COMPOSITIONS - A hem-curing epoxy resin composition, that includes an epoxy resin A having more than one epoxy group per molecule on average; a curing agent B for epoxy resins, which is activated at a temperature in a range of 100° C. to 220° C.; and an activator C for epoxy resin compositions, wherein activator C is a compound of formula (I), or is a reaction product between a compound of formula (Ia) and an isocyanate or an epoxide. | 09-26-2013 |
