Hercules Chemical Co. Inc.: Intumescent Sealant

Plumbers Firestop Sealant™ is a latex-based intumescent sealant that provides up to a three-hour fire rating. It expands up to 10 times to block flame propagation. According to the manufacturer, it is an excellent smoke seal and is designed for firestop applications in small commercial or grouped residential construction. In addition, it offers superb acoustical performance for reducing noise transmission, says the company. It can be used in systems where dynamic movement is expected such as plumbing, HVAC, metallic and nonmetallic pipes, conduits and tubing, insulated pipes, electrical and electronic cabling, and metal ductwork. It is water-based for easy cleanup and water-resistant when cured. The sealant will not separate or shrink when dry and is flexible, nonsagging, and paintable. It is now available in 5-gallon pails in addition to 10-ounce cartridges.
