CA 2743800

Compositions and methods for forming epoxy resin systems are provided. In one embodiment, a composition is provided for an epoxy resin system including a reaction product of an epoxy resin component and a curing agent component comprising a first amine compound having the formula R1R2R3N, wherein R1 and R2 are independently an aliphatic or alicyclic organic functional group and R3 is an alkyl group, having a backbone of 2-18 carbon atoms, and a second amine compound having one or more primary or secondary amine groups, with the stoichiometic ratio of -NH bonds of the second amine compound to the epoxy groups of the epoxy resin component being from 1:20 to about 21:20. The composition may be used to form composites, such as used in commercial wind turbine blade manufacturing.
