Properties: Gray white powder.No osmly a little taste bitter.Souble in acetone, alcohol, insoluble in Benzene,gasoline water.
Applications: Developed to replace thiurams such as TMTD where the presence of nitrosamines is of concern The dibenzylnitrosamine is not carcinogenic according to published literature. A fast curing primary secondary accelerator in NR, SBR NBR applications. Be safer to progress, providing longer scorch times than TMTD.Sometime used as retarder in the vulcanisation of PVC rubber.
Package: 25kg plastic woven bag, paper with plastic film bag, kraft paper bag.
Storage: The product should be stored in the dry 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 35οC can cause unusual compacted product. Since the date of production,the storage period is 12 months.
