Abstract
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.
