STI LC150 sealant is a latex-based, high solids firestop compound

This material, when properly installed, will effectively seal penetration openings against the spread of fire, smoke, toxic gasses and water. STI LC150 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 masons trowel or with a putty knife. STI LC150 dries without shrinking 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. STI LC150 is non-halogenated, contains no asbestos, inorganic fibers or solvents.
