Specified Technologies LC120 SpecSeal LC Endothermic Firestop Sealant, 20 oz

Keep network rooms, monitoring stations and security enclosures protected with Specified Technologies SpecSeal LC Endothermic Firestop Sealant — a gun-grade, latex-based firestop designed for construction joints and non-combustible penetrations. This SpecSeal LC120 20 oz sealant delivers reliable fire and smoke resistance by using endothermic fillers that absorb heat and release water vapor under fire exposure, slowing the progress of flame and smoke to protect critical surveillance, security and IT infrastructure.

The water-based formula is installer-friendly: it offers excellent caulking properties, high-build capability, easy cleanup, and is paintable when dry. High solids content minimizes shrinkage while the cured seal remains flexible to accommodate joint movement. Visible red color aids quick inspection, and the low-VOC, non-halogenated, asbestos-free composition supports safer indoor environments and code compliance for fire suppression & safety applications.

Use SpecSeal LC120 to seal cable penetrations, conduit and junction openings around fire-rated walls and floors. Order 20 oz cartridges today to improve passive fire protection and preserve uptime for your security and network systems.
