properties:the yellow powder (granule). the density is 1.37-1.40. no osmyl and no taste. soluble in benzene, acetone, ch2ci2, cs2, toluene, party soluble in alcohol and diethyl ether, insoluble in gasoline and water stabilization for storage
application:generally used as a secondary accelerator or as a booster for sulphenamides to achieve faster cure rate distinguished by very good processing safety in comparison with other thiurams, high curing activity and no discoloration. no cure activity in the absence of added elemental sulphur. an excellent accelerator for polychloroprene in association with dpg and sulphur.
packing:25kg plastic woven bag, paper with plastic film bag, kraft paper 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 product with pallet should not be stacked. stacking of palletized material or temperature of above 35℃ can cause unusual compacted product. the validity is 2 years.
