Abstract: The present invention relates to an epoxy resin system containing an epoxy resin and a mono-alkylated diamine. The epoxy resin system can further contain a second amine. The present invention also relates to a method for producing an epoxy resin system comprising combining an epoxy resin with a mono-alkylated diamine. The mono-alkylated diamines of this invention enhance desirable processing and cured properties of epoxy resin compositions without the negative impact on mechanical properties in the cured product normally seen with cycloaliphatic amine-based curing agents.

Abstract: A composite is produced by I. producing a reactive composition containing A) at least one organic diisocyanate and/or polyisocyanate; B) at least one compound having at least one functional group reactive toward NCO groups, wherein the ratio of NCO groups of A) and the functional groups of B) varies from 1:2 to 2:1; C) a catalyst mixture containing C1) at least one titanium compound and C2) at least one bismuth compound in a C1:C2 ratio of 100:1 to 1:100; and D) optionally, an additive; wherein the amounts of A)-D) add up to 100% by weight, II. directly impregnating a fibrous carrier with the composition from I., to obtain an impregnated fibrous carrier, III. shaping the impregnated fibrous carrier to give a molding, and IV. curing the reactive composition I.

Abstract: The invention relates to prepregs and composite components produced therefrom (mouldings), obtainable by the use of powdery reactive polyurethane compositions.

Abstract: The invention relates to prepregs and composite components (molding) produced therefrom at a low temperature, obtainable by using powdery highly reactive polyurethane compositions containing uretdione groups, with specific catalysts.
