SIL Silicone Firestop Sealant

A 100% silicone firestop sealant engineered to rapidly cure and resist washout when used in exposed conditions.

SpecSeal SIL300 Silicone Sealant is a one-part neutral curing silicone sealant that exhibits superior performance in applications where sealing apertures in walls and floors are needed to control the spread of fire, smoke, toxic gasses, and water during fire conditions. SIL300 Silicone Sealant reacts with atmospheric moisture to form a tough durable seal that will adhere to most building substrates without the use of primers. Pensil products do not contain asbestos or PCBs.

Common Applications:

  • Through-penetrations and joints
  • High temperatures or movement
  • Electrical, data, or telephone cables
  • Slab Edge/Curtain wall, safing and construction gaps
  • Seismic and expansion joints
  • Top-of-wall joints
  • Single or multiple metallic pipes, conduits & tubing
  • Features

  • 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)
  • Acoustically tested – reduces noise transmission
  • UL tested for W ratings
