Westco AO-2246 is a highly effective non-staining non-discoloring phenolic antioxidant.

Westco AO-2246 can be used as the primary stabilizer in a wide range of synthetic elastomers including polybutadiene, styrene-butadiene, neoprene, butyl, halobutyl and nitrile rubber. WESTCO AO-2246 is highly recommended for use in natural and synthetic latex rubber, latex products, caulks, sealants, and adhesives. WESTCO AO-2246 can be used in thermoplastic elastomers, polyurethane foams, engineering resins, ABS, and is recommended for evaluation in all clear, white or light-colored polymeric systems requiring protection against oxidation.
