Properties:

light yellow powder with light bitter taste. Specific density is 1.65-1.72. Hardly soluble in acetone, benzene, ethanol, and carbon tetrachloride. Insoluble in water, gasoline. Decomposed in strong acid and alkali. 
Application:

Used for NR, IR, SBR, NBR, EPDM and latex. May be regarded as an intermediate between URCC M and URCC DM. Used as a secondary accelerator in combination with URCC PZ and URCC EZ. Similar in performance to M at curing temperature in dry rubber application. Has somewhat low scorch and has processing safety. Suitable for mold curing. Requires zinc oxide and stearic acid as activators in many kinds of rubber batch. Easily disperses in rubber; yields non-staining and non-discoloring products. Mainly used for in the manufacture of latex products, foam rubber, latex coating gloves, etc. 
Package:

25kg N.W./bag, in plastic fabric laminated kraft bags lined with plastic bags. 
Storage:

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