  • Patent number: 9475904
    Abstract: 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.

  • Patent number: 9428912
    Abstract: 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.

  • Patent number: 9187592
    Abstract: 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.

  • Publication number: 20150300023
    Abstract: 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.
