STI SpecSeal 29 oz Tube LC Endothermic Firestop Sealant Deep Red LC129

SpecSeal LC endothermic sealant is a latex-based gun grade firestop sealant for construction joints and non-combustible penetrations. After application, LC sealant cures to form a flexible seal against the propagation of fire. Under fire exposure, LC absorbs heat and release water vapor resisting the progress of smoke and flame.
