New HoldRite firestop sealants

After the successful introduction of the first iteration of HoldRite firestop sealants in 2019, RWC is now offering an even more robust solution with the launch of the HydroFlame 300 self-leveling (HF300SL) and HydroFlame 300 caulk-grade (HF300CG) silicone firestop sealants.

First introduced in June 2020, the HF300SL and HF300CG are moisture-resistant silicone fire sealants designed for areas subjected to high levels of moisture or when UL listed W ratings are required. 

As quick curing silicone sealants, they can also be used across a variety of pipe types. The self-leveling HF300SL is designed for floor applications, while the HF300CG is a caulk-grade sealant designed for use on both floor and wall penetrations.

“The new iterations of our firestop sealants will provide contractors a solution that is both excellent for W ratings and washout conditions while also developing new efficiencies,” said Jeff Hamilton, firestop product manager at RWC. “HF300SL and HF300CG will simplify installation and create new standards to elevate contractors’ businesses, especially where W-rated sealants are needed.”
