20090118457 | Resorcinol-based mannich base - The invention relates to Mannich bases that can be produced from resorcinol, formaldehyde, and triethylenetetramine and/or tetraethylenepentamine. Also disclosed are a method for the production thereof and the use thereof as hardeners for amine-reactive compounds. The inventive Mannich bases are particularly suitable as hardener components in adhesives. | 05-07-2009 |
20090247708 | Amino group-terminal viscosifiers, resultant products and uses thereof - The invention relates to compounds embodying amino group-terminal viscosifiers, the resultant products thereof, and the uses thereof. The inventive viscosifiers are provided with formula (I), wherein R | 10-01-2009 |
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 |
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 |
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 |
20130225723 | CONDENSATION PRODUCTS OF AMINO-FUNCTIONAL POLYMERS - A condensation product of at least one (hydroxymethyl)phenol and at least one polyoxyalkylene diamine and a process for the preparation thereof and the use thereof in the curing of epoxy resin systems are described. | 08-29-2013 |
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 |
20150018500 | NEW REACTIVE POLYMER CATALYSTS FOR 2-COMPONENT EPOXY RESIN SYSTEMS - An oligomeric condensation product can be obtained from at least one (hydroxymethyl)phenol of general formula (I), | 01-15-2015 |
