Light yellow powder (granule), micro smell, bitter, non-toxic, the proportion of 1.42-1.52, above the melting point of 171 DEG C, soluble in dilute solution of ethyl acetate, acetone, sodium hydroxide and sodium carbonate, soluble in ethanol, insoluble in benzene, insoluble in water and gasoline. Storage stability. In case of dust explosion limit is 21g/m3.
Mainly used for IR, NR, SBR, NBR, HR and EPOM system, is currently a major acid curing agent, with moderate curing rate, and other curing agents such as WIlLLING DM and WIlLLING TMTD as curing agent and alkaline reach higher activity can be used. The curing temperature is low, no pollution, easy to disperse in rubber, mainly used in the manufacture of tires, rubber belt, rubber shoes and other industrial rubber products, but can not be used in food materials.
