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.
