Abstract: Provided is a curable composition containing a reactive mixture of components including an polyethersulfone having a chemical group reactive with an epoxide, a cycloaliphatic polyepoxide resin, a polyepoxide having a functionality greater than two, a liquid diepoxide resin, a first curative containing 9,9-bis(aminophenyl)fluorene or a derivative therefrom and having a curing onset temperature of from 150° C. to 200° C. The components can further comprise a second curative having a curing onset temperature of from 60° C. to 180° C. When thermally curing this composition, the second epoxy curative starts to cure before the first epoxy curative, thereby inhibiting vertical flow of the adhesive during the curing process.

Abstract: Disclosed is a curable composition and cured products thereof. The curable composition includes a vinyl polysiloxane component, a hydrogen polysiloxane component, a polymerization catalyst, and an expandable graphite component comprising moisture. Cured products of the curable composition include foamed cells having a uniform size and distribution in the cured product. This can help to increase the water proofing and flame retardant properties of the cured product.
