SpecSeal® Series SIL Silicone Firestop Sealant is a one-part,neutral-curing silicone sealant exhibiting superior performance in applications where sealing openings in walls and floors are needed to control the spread of fire, smoke, toxic gasses, and water during fire conditions.
SpecSeal® Series SIL Silicone Firestop Sealant reacts with atmospheric moisture to form a high-strength, durable seal that will adhere to most building substrates without the use of primers. SpecSeal® products do not contain asbestos or PCBs.
BASIC USES:
SpecSeal® Series SIL Silicone Firestop Sealant is designed for use in firestop systems for through penetrations and joints. This product excels in applications where greater water resistance is required. Systems have been tested for Class 1 W Ratings per UL1479.
SpecSeal® Series SIL Silicone Firestop Sealant is available in non-sag (SIL300) and self-leveling (SIL300SL) grades and may also be used to seal vertical and horizontal joints between metals, masonry, concrete and other common construction materials. SpecSeal® Series SIL Silicone Firestop Sealant is specially designed for use in static or dynamic joints. The low modulus characteristic minimizes strain on the substrate surface and the elastomeric quality allows excellent recovery from extension and compression cycling.
- Low modulus – allows up to ± 50% movement capability.
- Auto-bonding – allows fresh sealant to adhere to cured sealant.
- Excellent water-resistance – for water-tight sealing.
- Ozone and UV-resistant – for excellent weathering ability and long service life.
- Excellent chemical resistance – best choice in polluted or corrosive atmospheres.
- Excellent adhesion to most building substrates (primerless adhesion).
- UL tested for W ratings.
- Acoustically tested – reduces noise transmission
