Fire-rated Sealants

How can we limit the spread of fire when it comes to building design? Including passive fire-protection in a building design helps contain fire and smoke, allowing more time for building occupants to escape. This is why building materials we select are so vital: the materials’ behavior in resisting fire is a key factor in determining how much time will be available to exit a building. Dow High Performance Building offers a range of DOWSIL™ brand solutions for vertical and horizontal applications as well as cable penetrations, fenestrations and building element connections, including DOWSIL™ Smoke Seal 800SL.

A distinct advantage

Sealants can help limit the spread of fire and smoke in passive, fire-protective building designs. Silicone technologies are non-flame propagating, do not produce flaming droplets and have a limited non-toxic smoke development. These material properties can be especially beneficial in fire-rated systems and designs and are found in DOWSIL™ Smoke Seal 800SL, developed for joints in floors and the gap between walls and floors. This product has a fire rating of up to four hours and benefits from the renowned characteristics of silicone sealants, such as movement capability, adhesion profile, UV and temperature stability and durability.
