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.
                            提供了可用于固化环氧
树脂的复合颗粒。更具体地说,复合颗粒具有多孔聚合物芯颗粒、位于多孔聚合物芯颗粒内的环氧
树脂固化剂和/或固化催化剂,以及围绕多孔聚合物芯颗粒的含
氟聚合物涂层。此外,还提供了含有环氧
树脂和复合颗粒的混合物的可固化组合物。环氧
树脂通常不会发生反应,直到加热固化组合物,使固化剂和/或固化催化剂从复合颗粒中释放出来。此外,还提供了由可固化组合物形成的固化组合物。
