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.
