Meeting ASTM E814(UL1479) and ASTM E119 requirements, STI SpecSeal LC Endothermic Sealant is a safe-to-use water based firestop device made to seal penetrations while keeping fire, smoke, toxic fumes and water from passing.

Using a High Solids Formula, series LC firestop sealant will attach to all construction surfaces and will not shrink when it dries.

A premium latex binder allows STI endothermic sealant the flexibility to easily fill penetrations while working with caulk guns, trowels or putty knives.
