Abstract: 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.

Abstract: A thermal indicator, a thermal indicating composition (1), as well as two kinds of thermal indicating structures (11) are disclosed. The thermal indicator comprises an organic solid material (2) having a melting point higher than ambient temperature and a dye (3) which contacts the organic solid material (2) and is capable of being dissolved in the organic solid material (2) when the thermal indicator is heated to the melting point of the organic solid material (2). The thermal indicator, the thermal indicating composition (1), as well as these two kinds of thermal indicating structures (1) have simple structures and can be manufactured by a simple process. Furthermore, the existence of the dye (3) in its crystalline state offers significant resistance to UV radiation in outdoor applications.

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.
