2. Application:

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,foot wear,rubber belts and hoses etc.

3. Property:

It is light yellow powder(granule) with a little osmyl and taste bitter. The density is 1.42-1.52 Soluble in ethyl acetate, ethanol, acetone, solution of NaOH and Na2CO3, insoluble in benzene, water and gasoline. Good storage stability. Lower explosion limit is 21g/m^3.
