3M™ Smoke and Sound Sealant SS 100 is an economical, ready to use, gun-grade, elastomeric sealant that dries to form a monolithic flexible seal that helps prevent unwanted noise infiltration and mitigates the spread of smoke and toxic gas during a fire. 3M™ Smoke and Sound Sealant SS 100 is designed to seal construction joints and through penetrations in non-fire-rated wall and floor assemblies, including smoke partitions and acoustic assemblies. In addition, this product acts as a draftstop to prevent unwanted air movement and provides a barrier against dust and other airborne particulates.
