Biostop 500+ is a one component, general purpose fire rated sealant and smoke seal for construction joints and around penetrations through fire rated walls and floors. Biostop 500+ is a water based, extremely intumescent, 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 500+ 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 500+ 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 500+ is rated for 1, 2, 3 and 4 hours and has been tested in accordance with the ASTM E814, (UL 1479), UL 2079 and ULCS115-95 test standards.
