SpecSeal SSS Sealant is a latex based, high solids firestop compound. This firestop will effectively seal penetration openings against the spread of fire, smoke, hot gasses and water. SpecSeal SSS Sealant features STI’s patented and proprietary two-stage intumescent technology. When exposed to high temperatures or fire, this material expands aggressively in a highly directionalized fashion to quickly close off voids left by the burning or melting of combustible materials.
