Properties: Light yellow powder (granule) with a little bitter, no poison. The density is 1.70, the decomposable temperature is 300οC. Soluble in chloroform, acetone, partly soluble in benzene, ethanol, CCl4, insoluble in gasoline, water and ethyl acetate. Decomposion when meeting strong acid and strong alkali
Application: Used for NR,IR,SBR,NBR, EPDM and latex. May be regarded as an intermediate between WILLING M and WILLING DM. Used as a secondary accelerator in combination with WILLING PZ andWILLING EZ. Similar performance as WILLING MBT at curing temperature in dry rubber application. Has lower scorch and better processing safety. Suitable for mold curing. Require 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 in the manufacture of latex products, foam rubber, latex coating gloves, etc
Packaging: 25kg plastic woven bag,paper with plastic film bag,kraft paper bag,or jumbo bag.
Storage: The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 2 years.
