Bostik Intucrylic Intumescent Acrylic Sealant White 310m is a high-quality water-borne acrylic intumescent building sealant. It cures to form a tough, tack-free seal with excellent adhesion to a wide variety of building surfaces. In the event of a fire, Bostik Intucrylic will swell (intumesce) to form an insulting char, which is fire resistant and will resist the passage of smoke and flames.
