HoldRite HydroFlame 100, MPN HF100-20S, is an elastomeric water-based firestop sealant designed for effective sealing in areas with expected dynamic movement. This sealant is suitable for new and existing penetrations in interior rated gypsum, concrete, and block walls. It can also be applied on rated concrete floors and wood floor ceiling assemblies. When installed properly, it prevents smoke, gases, and flames from passing through around penetrating items. HydroFlame 100 is ready to use and requires no thinning or mixing. It can be dispensed from standard caulking guns and bulk loaders.
This sealant meets UL system ratings and is effective for firestop applications.
