ASMACO FIRESTOP SILICONE SEALANT offers exceptional fire resistance and durability in high-risk applications. Its low-modulus, neutral-curing formulation ensures flexibility and compatibility with a wide range of substrates, including stone, steel, masonry, and wood. This eliminates the need for priming, streamlining installation and saving time on-site. It is engineered for critical uses such as weather-sealing building facades, sealing fire-rated expansion joints, and securely sealing around pipes and cables passing through fire-rated walls. The sealant maintains its integrity under exposure to high temperatures, ensuring a reliable barrier against the spread of fire, smoke, and toxic gases, while also providing excellent weather resistance for long-term performance in both interior and exterior environments.
