It is light yellow(granule), slightly foul odor and bitter taste, nonpoisonous. Specific gravity: 1.46-1.52. Soluble in ethyl acetone, acetone, dilute solution of sodium hydroxide and sodium carbonate, ethyl alcohol. Not easily soluble in benzene. Insoluble in water and gasoline.
Used as an acid accelerator currently and a medium fast primary accelerator. Imparts excellent aging properties when used both alone and in combination with MBTS, TMTD and many other basic accelerators for higher activity. Its accelerative temperature is low and easily be dispersed with lower pollution. Mainly used in the manufacture of tires, tubes, footwear, rubber belts and hoses etc.
