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.
BIOSTOP BF 150+ can be used in interior applications as a general purpose fire rated sealant and smoke seal for construction joints on both vertical and horizontal surfaces.
