The new Hilti Intumescent firestop sealant FS-ONE MAX is an improved version of the popular Firestop sealant FS-ONE. It still includes the reliable features of the FS-ONE but now provides for better handling and longer shelf life.
This new W-rated, multi-purpose formulation means this highly versatile product can be used for even more common through-penetrations in a variety of base materials including concrete, masonry and drywall. It is easy to dispense and is available in multiple package types (tubes, foil packs and buckets). The 12 month shelf life from date of manufacture helps reduce the risk of expired inventory.
Now ethylene glycol free and low VOC content makes it an environmentally safe formulation and is non-harmful when used as directed.
