Properties: 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, solution of NaOH and Na2C03, insoluble in benzene, water and gasoline. Good storage stability. lower explosion limit is 21g/m3

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 WILLING DM, WILLING 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

Packaging: 25kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bag

Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 2 years when stored under normal conditions.
