Title: COMPOSITE PARTICLES FOR CURING EPOXY RESIN COMPOSITIONS AND CURABLE AND CURED EPOXY RESIN COMPOSITIONS PREPARED USING THE PARTICLES
Abstract:
Composite particles are provided that can be used to cure epoxy resins. More particularly, the composite particles have a porous polymeric core particle, a curing agent and/or a curing catalyst for an epoxy resin positioned within the porous polymeric core particle, and a fluoropolymer-containing coating layer around the porous polymeric core particle. Additionally, curable compositions are provided that are mixtures containing an epoxy resin and the composite particles. The epoxy resin typically does not react until the curable composition is heated causing the release of the curing agent and/or curing catalyst from the composite particle. Further, cured compositions formed from the curable composition are provided.
