Fire Sealants and Fireproof Silicones
Innovative, protective firestop sealing solutions for fire-rated applications.
Meet fire codes without sacrificing performance
Fire-resistant sealants and adhesives from Dow help you design fire systems with confidence, ensuring that risks to buildings – and building occupants – are minimized. Designed to help limit the spread of fire, smoke and gases and meet building codes and regulations, fire-rated sealants:
- Can be used for penetration seals, horizontal and vertical linear joints in walls and in floors as well as at the connection between walls and floors.
- Help to isolate toxic gases, pollutants and other deleterious gases during a fire event.
- Are non-flame propagating and do not produce flaming droplets.
Our fire-retardant solutions are available in selected countries. DOWSIL™ Sealants have been certified to both European and UL fire standards in a wide range of joint and penetration configurations including sealants for firestop systems described in the Products Certified for Canada.
