Product Description<\/h3>\n

The STI SpecSeal\u00ae LC Endothermic Firestop Sealant<\/strong> is a high-solids, latex-based firestop compound<\/strong> formulated with endothermic fillers that absorb heat and release water during fire exposure.
\nIt effectively seals joints and penetrations against fire, smoke, hot gases, and water<\/strong>, forming a flexible, durable barrier.
\nNon-halogenated and asbestos-free, it is engineered for easy application by caulking or troweling on walls, floors, and around non-combustible penetrants.<\/p>\n

\n
