TAMMSFLEX NS and TAMMSFLEX SL sealants are two-part, elastomeric, polysulfide caulking and sealing compounds. It cures at normal temperatures creating a tough elastomeric seal that adheres tenaciously to masonry, metal and wood. It will withstand repeated expansion and contraction and remain resilient through daily and seasonal cyclic changes in temperature. It has excellent chemical, solvent, and water resistance and will withstand joint movement of up to ±25%.
