SpecSeal SIL400 Silicone Firestop Sealant

SpecSeal SIL400 Silicone Sealant is a high-performance silicone firestop sealant tested to resist the passage of smoke, flame, and water through construction joints and through-penetrations. SIL400 Sealant cures to form a flexible seal and carries a Class 1 W Rating for water resistance (per ANSI/UL1479). The sealant is a one-part, neutral-curing silicone that will adhere to most building substrates without the use of primers. The sealant is low modulus minimizing strain on the substrate surface while the elastomeric quality allows excellent recovery from extension and compression cycling.
