20100108258 | HOT-CURING EPOXY RESIN COMPOSITIONS THAT CAN BE USED AS BODYSHELL ADHESIVE OR STRUCTURAL FOAM - Hot-curing epoxy resin compositions are disclosed which firstly are solid in a hardened state at room temperature and secondly form an adhesion-free surface and are impact-resistant and can have high glass transition temperatures, above, for example, 110° C. An exemplary hot-curing epoxy resin composition can form separate phases on hardening, a continuous phase being formed by epoxy resins. If the compositions include a blowing agent, they can have excellent suitability for production of foams, such as structural foams. | 05-06-2010 |
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 |
20130089723 | COMPOSITION FOR FLEXIBLE MEMBRANES - A composition including a styrene block copolymer, a polar-modified styrene block copolymer, plant fibers and a polyolefin solid at 25° C., and to molded bodies, especially membranes, produced from such compositions. | 04-11-2013 |
20150044459 | CURABLE COMPOSITION SUITABLE FOR THE BONDING OF PLASTICIZED PVC - The invention relates to the use of a composition comprising methyl methacrylate MMA, at least one elastomer and/or a core-shell polymer, and at least one radical former, as an adhesive, sealant or coating for gluing, sealing or coating substrates containing plasticized PVC. | 02-12-2015 |
20150118404 | PVC MEMBRANE WITH REDUCED PLASTICIZER MIGRATION - The present invention relates to a membrane comprising a bulkhead layer, wherein more than 50% by weight of the bulkhead layer is composed of PVC, and a barrier layer. The barrier layer can, on the one hand, be a barrier layer S1, wherein the barrier layer S1 has a polyvinyl alcohol layer comprising more than 50% by weight of copolymer PA, which is connected to the bulkhead layer by a polyurethane layer, wherein more than 10% by weight of the polyurethane layer is composed of polyurethane PUR. The barrier layer can, on the other hand, be a barrier layer S2, wherein the barrier layer S2 has a composition comprising 5-50% by weight of polyurethane PUR and 50-95% by weight of copolymer PA. The membranes according to the invention have significantly lower plasticizer migration compared to the membranes of the prior art and are distinguished by improved resistance to aging, particularly as regards the adherence of the barrier layer on the bulkhead layer, and imperviousness to damp. | 04-30-2015 |
20150232686 | ADHESION PROMOTER COMPOSITION FOR POLYOLEFINIC MEMBRANES - Composition, comprising—at least one organic polymer,—at least one monomer from the group of acrylates,—at least one catalyst from the group of tertiary organic amines,—at least one solvent. | 08-20-2015 |
20150275059 | HOT-CURING EPOXY RESIN COMPOSITIONS THAT CAN BE USED AS BODYSHELL ADHESIVE OR STRUCTURAL FOAM - A hot-curing epoxy resin composition including: at least one liquid epoxy resin having an average of more than one epoxy group per molecule; at least one solid epoxy resin having an average of more than one epoxy group per molecule; at least one polymeric impact modifier comprising a functionalized, epoxy-terminated, acrylonitrile/butadiene copolymer; at least one homopolymer, solid at room temperature, of an olefinically unsaturated monomer; and at least one epoxy-resin hardener which is activated via an elevated temperature, with a proportion by weight of the polymeric impact modifier, based on the epoxy resin composition, being smaller than 20% by weight, and an amount by weight of the homopolymer, solid at room temperature, being greater than the amount by weight of the polymeric impact modifier. | 10-01-2015 |
20150300023 | PVC MEMBRANE WITH REDUCED PLASTICIZER MIGRATION - The invention relates to a membrane including a partition layer, wherein the partition layer contains at least 50 wt % of PVC, and a barrier layer. The barrier layer can be a barrier layer, wherein the barrier layer has a polyamide layer containing more than 50 wt % of copolymer, wherein said polyamide layer is connected to the partition layer by a polyurethane layer, wherein the polyurethane layer contains more than 10 wt % of polyurethane. Alternatively, the barrier layer can be a barrier layer, wherein the barrier layer is made of a composition containing 5-50 wt % of polyurethane and 50-95 wt % of copolymer. The membranes according to the invention have significantly lower plasticizer migration compared to the membranes of the prior art and are characterized by improved aging resistance, in particular with regard to the adhesion of the barrier layer to the partition layer, and impermeability to moisture. | 10-22-2015 |
