HoldRite HydroFlame 200 is a firestop sealant designed for various building materials. Its elastomeric, water-based formula is suitable for new and existing penetrations through interior rated gypsum, concrete, and block walls. This sealant provides a barrier against smoke, gases, and flames while maintaining flexibility in areas with dynamic movement.
HydroFlame 200 is ready to use straight from the package and requires no thinning or mixing. Its high-performance intumescent properties expand when exposed to heat, creating an effective seal.
