Properties: White crystalline powder. Soluble in alcohol, partly soluble in diethyl ether, insoluble in water.
Application: DBTU is an ultra-accelerator for mercaptan-modified CR (1-3phr). It has a vulcanization behavior similar to that of ETU and DETU. It is also used as a second accelerator for NR and synthetic rubbers. It disperses easily in rubber. It is non-staining and does not bloom. It is practically odorless antioxidant for NR, antiozonant for NR and SR, particularly for SBR. It is also a corrosion inhibitor.
Packing: In 25kgs 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.
