CURABLE AND CURED EPOXY RESIN COMPOSITIONS

摘要

Curable epoxy resin compositions are provided that are mixtures containing an epoxy resin and composite particles. The composite particles have a porous polymeric core, a nitrogen-based curing agent for an epoxy resin positioned within the porous polymeric core, and a coating layer around the porous polymeric core. The nitrogen-containing curing agent typically does not react with the epoxy resin until the curable composition is heated causing the release of the nitrogen-containing curing agent from the composite particle. Additionally, cured epoxy resins formed from the curable composition and method of forming cured epoxy resins are provided.
