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.
SpecSeal® SSS Sealant’s unique multi-viscosity formula yields a single component sealant that has excellent caulking properties as well as high build properties on vertical or overhead surfaces. This single component sealant may be pumped, caulked (standard cartridge or bulk loaded), knifed or troweled. In addition, SpecSeal SSS Sealant does not contain PCB’s or asbestos.
SpecSeal® SSS Sealant is storage stable (when stored according to the manufacturer’s recommendations) and will not separate nor shrink when dried (when applied according to the manufacturer's recommendations). SpecSeal® SSS Sealant will adhere to all common construction and penetrant materials and contains no solvents that might adversely effect plastic pipes or cable jackets.
