Bio Fireshield BIOSTOP BF 150+ Intumescent Firestopping Sealant - 30 oz Tube

BIOSTOP® BF 150+ is a one component, general purpose fire rated sealant and smoke seal for construction joints and through-penetrations. BIOSTOP® BF 150+ is a water based, non-sag, caulking grade sealant that is easy to apply as well as to retrofit. It cures to an elastomeric seal that is suitable where dynamic movement is expected. In the event of a fire, BIOSTOP® BF 150+ will prevent the spread of flames, smoke, hot gases and water through joint openings and through-penetrations. No dilution or mixing is required for use. No special skills are necessary for installation. BIOSTOP® BF150+ is applied with a conventional caulking gun, bulk loading gun or can be troweled from the pail. For large applications, it can be pumped directly from the pail. BIOSTOP® BF 150+ systems are rated for 1 and 2 hours in accordance with ASTM E814 (UL1479) and ASTM E1966 (UL 2079) test standards. BIOSTOP® BF 150+ is protected in a wet stage as well as in a dry stage against mold growth with a combination of biocides.
