Joint Seal Aliphatic is a 2-component UV stable elastomeric sealing polymer system designed to act as a crack filler primarily in concrete. This material provides exceptional adhesion characteristics and fast cure times. It is highly chemical resistant, insensitive to water, abrasion resistant and remains thermally stable in a range of -20°F (-29 C) to 250°F (125 C). It may be used under traditional floor coatings or any of our top-coating materials. Joint Seal is used in heavy traffic warehouse floors, refrigeration floors, chemical spill prone floors, pothole road repair or under ceramic tile floors. It meets FDA regulations for indirect food contact (CFR 21, Sec. 175-300).
