Product Description

Dow Corning 2942160 DOWSIL FIRESTOP 400 WHITE is an intumescent acrylic firestop putty cartridge with a 310ml capacity, engineered to provide fire and smoke-resistant sealing for internal pointing applications around door and window frames, as well as small joints where fire-rated partitions meet.
