Fire Barrier Sealant IC 15WB+
Product Data Sheet
1. Product Description 3M
™
Fire Barrier Sealant IC 15WB+ is a cost-effective, one-part,
gun-grade, latex-based, intumescent firestop sealant that dries to form a monolithic firestop seal that also acts
as a barrier to airborne sound transmission. 3M
™
Fire Barrier Sealant IC 15WB+ firestops through penetrations
passing through fire-rated floor, floor/ceiling or wall assemblies, as well as other fire-rated interior building
partitions and assemblies (e.g. static construction joints or blank openings). In addition, the unique intumescent
property of this material allows 3M
™
Fire Barrier Sealant IC 15WB+ to expand and help maintain a firestop
penetration seal for up to 3 hours as penetrants are exposed to fire. 3M
™
Fire Barrier Sealant IC 15WB+
bonds to most construction substrates, including: gypsum wallboard, concrete, metals, wood, plastic (including
CPVC) and cable jacketing. No mixing is required.

2. Applications 3M
™
Fire Barrier Sealant IC 15WB+ is a general-purpose intumescent firestop ideal for sealing single or multiple
through penetrations in fire-rated construction. 3M
™
Fire Barrier Sealant IC 15WB+ is typically used in mechanical, electrical and plumbing applications
to firestop openings created by the following penetrations in fire-rated floors, floor/ceilings or walls: metallic pipe, plastic pipe, conduit, power and
communication cable, cable trays, busways, combos, insulated pipe and HVAC duct penetrations. 3M
™
Fire Barrier Sealant IC 15WB+ is also used to
firestop blank openings and static construction joints.
