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: A battery assembly comprises an assembly housing, a plurality of battery modules disposed within the assembly housing and electrically coupled to a busbar, and at least one ceramifiable pad disposed within the assembly housing. Each battery module comprises a plurality of individual cells disposed within a module housing. The at least one ceramifiable pad is disposed between at least one of: at least two of the individual cells, at least two of the battery modules, the busbar and the assembly housing, or at least one of the battery modules and the assembly housing. The ceramifiable pad comprises a ceramifiable composition. Heating the ceramifiable composition to a temperature between 600 and 1600° C., inclusive, results in a ceramified composition. Ceramifiable compositions and methods of making them are also disclosed.

Abstract: Provided is a curative part usable in a two-part curable composition. The curative part includes a liquid amine; a heterogeneous dispersant; and core-shell rubber particles having an elastomeric core and a (meth)acrylic shell. The core-shell rubber particles and the heterogeneous dispersant can be collectively shear-dispersed in the liquid amine such that the core-shell rubber particles are substantially non-aggregated and the curative part is phase-stable over a period of at least 3 months at ambient temperature. Advantageously, large amounts of core-shell rubber particles can thus be incorporated into a cured resin matrix, which can afford significantly enhanced impact performance.
