Intumescent Firestop Sealant
A Common Product profile (CP) is a type of data record originally developed as part of a collaboration called the Quartz Project. The profiles are not specific to any manufacturer, but list the substances that are most commonly present in a product type. The CPs include a general description of the product type, a list of the most common substances serving each function in the product, and the health hazards associated with these substances. See the CP methodology here for more information.
This CP is based on research done for the Quartz Project. Some records may reflect updates made by HBN following the completion of the Quartz effort. In addition, health profile and process chemistry information here is linked to the Pharos Chemical and Material Library (CML). The CML is regularly updated as hazard lists and research evolves, so this hazard display may not match the snapshot shown in the Quartz database.Representative Manufacturers
Intumescent firestop sealants are used to seal joints and voids in fire-rated assemblies, including around through penetrations such as pipes, HVAC ducting, cables, etc. The sealant offers good adhesion to a variety of surfaces including metal, plastic, drywall, concrete, and wood. The sealant contains fire resistant and intumescent materials to prevent the spread of fire and smoke through the protected joints and penetrations. The most common material is water-based with an elastomeric acrylic polymer binder. The material is supplied in tubes or pails for application with a caulk gun, trowel or putty knife. While the primary purpose of these sealants is fire protection, they do also decrease sound transmission through the sealed voids.
This information reflects our best understanding of product composition in 2015.
