Self Seal Firetops

Self-Seal® GG-266 is a single-component, neutral cure, non-slumping intumescent silicone caulk that is designed to seal combustible service penetrations in fire-rated walls and floors. When exposed to temperatures in excess of 150°C (300°F) it will begin to expand. As the combustible penetrating item softens and collapses under fire conditions, the silicone composition will rapidly intumesce to fill the void with a patented char composite that contains expanded graphite.

Self-Seal® SL-100 Self-Leveling Silicone Firestop is a single-component, low modulus, self-leveling silicone firestop sealant designed for floor applications. Its self-leveling property reduces labor costs (little or no tooling required) particularly around congested service penetrations assuring that all voids are sealed. It forms a pressure tight seal resistant to water, smoke and toxic gases, see Self-Seal®UL and cUL firestop systems for W (Water tightness) and L (Air Leakage) Ratings. The sealant is also resistant to cracking, ultraviolet radiation and ozone.

Self-Seal® GG-200 is a single-component, low modulus, non-slumping silicone firestop sealant designed for horizontal and verticle applications. It forms a pressure tight seal resistant to water, smoke and toxic gases, see Self-Seal® UL and cUL firestop systems for W (Water tightness) and L (Air Leakage) Ratings. The sealant is also resistant to cracking, ultraviolet radiation and ozone.
