SpecSeal LC 150 Series Sealant

SpecSeal LC 150 Endothermic Sealant is a latex-based gun grade firestop sealant for construction joints and non-combustible penetrations. SpecSeal® LC Sealant is engineered to adhere well to virtually all construction surfaces and may be applied using a standard caulk gun or by troweling with a standard mason’s trowel or with a putty knife. After application, LC Sealant cures to form a flexible seal against the propagation of fire. Under fire exposure, LC absorbs heat and releases water vapor resisting the progress of smoke and flame.
