Latent curing agent and composition

摘要: A latent curing agent for an epoxy resin containing a (A) and coating said resin, wherein the comprises structure in which two of (structure (1)) are bonded via urea bonding, (1) being obtained by bonding three sulfur atoms at branching point linear or cyclic aliphatic hydrocarbon group optionally ester structure, least one nitrogen each is incorporated into bonding; component composition using agent. The above can exhibit high curability storage stability combination. suitably used producing composition, provide anisotropic electroconductive material, adhesive insulating sealing material like exhibits stability, also adhesion reliability strength sealability.
