Zusammenfassung:	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.
