Overview
LOWINOX™ AH25 is a sterically hindered phenolic antioxidant that provides excellent protection for unvulcanized rubber adhesives, tapes, and films from oxygen and UV-initiated cracking. It prevents tack loss and reduces the cold flow of unvulcanized rubber. LOWINOX™ AH25 is a very effective stabilizer and antiskinning agent for a variety of coatings, and provides scorch protection in wire and cable applications. This antioxidant also provides acrylonitrile-based polymers with excellent stabilization performance.
