STI SpecSeal LC 20 oz Sausage Endothermic Firestop Sealant Deep Red LC120

SpecSeal LC Sealant is a latex-based, high solids firestop compound. This material, when properly installed, will effectively seal penetration openings and joints against the spread of fifire, smoke, hot gasses and water. 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. SpecSeal LC Sealant dries to form a flexible shield against the propagation of fire. Its premium latex binder system is totally resistant to water and will not re-emulsify after drying. SpecSeal LC Sealant is non-halogenated, contains no asbestos or inorganic fibers.
