Sterically hindered phenolic antioxidant designed for use in unvulcanized rubber, giving excellent protection from oxygen and UV exposure.
Product 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 cold flow of unvulcanized rubber. LOWINOX™ AH25 is a very effective stabilizer and anti-skinning agent for a variety of coatings, and provides scorch protection in wire and cable applications.
