Dow Corning Firestop Putty Aerosol


The Dow Corning white, 310ml firestop putty cartridge is an intumescent acrylic sealant for internal pointing around the door and window frames where damage due to smoke and flame needs to be kept to a minimum and in the small joints formed where fire-rated partition sections meet. It has intumescent qualities which enable the material to swell under heat conditions to produce a fire and smoke-resistant seal.
