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.

Abstract: The two-part composition includes a first part and a second part. The first part includes a vinyl-substituted polysiloxane, a hydrosilylation catalyst, expandable graphite comprising moisture, and first polymeric microspheres having been at least partially coated with inorganic filler. The second part includes a second vinyl-substituted polysiloxane, a hydrosilyl-substituted polysiloxane, and second polymeric microspheres having been at least partially coated with flame-retardant inorganic filler. The two-part composition is useful, for example, for curing into a sealant and making an assembly. The assembly has a first substrate and a second substrate with a cured product of the two-part composition in contact with the first substrate and the second substrate. Methods of making a sealant and an assembly are also described.

Abstract: The composition includes a vinyl-substituted polysiloxane having at least two vinyl groups, a hydrosilylation catalyst, a hydrosilyl-substituted polysiloxane having at least two silicon-hydride groups, and a phosphorous-containing flame retardant encapsulated in a crosslinked, nitrogen-containing polymer. The composition may be a two-part composition including a first part and a second part. The first part includes a vinyl-substituted polysiloxane, a hydrosilylation catalyst, and a phosphorous-containing flame retardant encapsulated in a crosslinked, nitrogen-containing polymer. The second part includes a second vinyl-substituted polysiloxane and a hydrosilyl-substituted polysiloxane. A battery module including a plurality of battery cells and the composition at least partially encasing the plurality of battery cells is also disclosed.
