Specifications

Characteristics Antioxidant 2246 is soluble in benzene, acetone, tetrachloromethane and alcohol, but insoluble in water. Its relative density is 1.04, and solubility over 2%. It maybe present pink color after long time storage which doesn’t affect efficiency.

Applications 2246is general phenol antioxidant, non-toxic, non-stain, non-discoloring, and resists heat energy, oxygen and fracturing. It has perfect protection to rubber products, even more prominent effect to latex products. It is especially applicable for light-colored, colored or white products of  styrene-butadiene or butadiene latex, and the dosage is 0.25～1.5, only 30～50% of antioxidant 264. It also has good application in PU adhesive.
