ABSTRACT:
Disclosed is a hardening agent composition for epoxy resins in the form of powdery grains, comprising a low-reactive hardening agent, a hardening promoter, a zeolite and at least one additive selected from a water-repellent fine silica powder, a silane coupling agent and a polysiloxane compound, whereby the additive is adhered to the surfaces of the powdery grains. The composition has a retarded water-absorbing property and has improved storage stability, when blended with an epoxy resin to form a thermosetting epoxy resin composition. Methods for preparing the powdery hardening agent composition are also disclosed.
