| Application | Developed to replace thiurams such as RTENZA TMTD where the presence of nitrosamines is of concern. The dibenzyl nitrosamine is not carcinogenic according to published literature. A fast curing primary secondary accelerator in NR, SBR and NBR applications. Be safer to process, providing longer scorch times than RTENZA TMTD. Sometime used as retarder in the vulcanization of PVC rubber. |
| Package | 25kg 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 1 year. |
