Soluble in chloroform, toluene, benzene, carbon tetrachloride. Insoluble in water and ethyl alcohol. Application: given flat, moderately fast cures in nr and sr. Also used in a wide range of general purpose rubber. Non-staining/non-discolouring in "white" socks; use as a plasticiser and/or retarder in polychloroprene rubber. Secondary acceleration is usually required for synth etic polymers. Better scorch safety than mbt. Storage: keep container tightly closed in a cool, well-ventilated place. The recommended max. Storage life is 2 years when stored under normal conditions. Packaging: 20kg bag.
