3M™ CP25WB+ Fire Barrier Caulk is a water based, premium,
intumescent, latex-based sealant offering outstanding fire
performance plus a non-halogen formula. In addition, the unique
intumescent property (expanding when heated) means that as cable
and pipe insulation is consumed by fire, 3M Fire Barrier Caulk
expands to fill and hold the penetration closed. As little as 1/2
inch (13 millimeter) can effectively firestop the opening. Bonds to
concrete, metals, wood and cable jacketing. No mixing required.
Dries tack-free in approximately ten to 15 minutes and is paintable
after a 72 hour cure. Only minimal amounts necessary to fill the
void
