Performance:Gray white powder, taste slightly bitter, odorless. The relative density is 1.01~1.02, soluble in ethanol, acetone, chloroform, slightly soluble in benzene, insoluble in gasoline and water.
Use:DOTG leads to a very slow vulcanization start and a relatively slow vulcanization rate, and DOTG alone can cause severe reversion, so it is necessary to use an effective accelerator. When DOTG and thiols, sulfenamides, thiuram and dithiocarbamate accelerators are used together, synergistic effect and secondary promotion effect can be obtained, crosslinking density and curing speed are improved, and the mechanical properties and anti-aging properties of vulcanizates are good. DOTG has no blooming phenomenon in vulcanization and is mainly used for vulcanization of acrylate rubber.
Packing:Composite paper bag, lined with plastic film bag, net weight 20kg.
Storage:Sealed and stored in a cool, dry, well-ventilated place, away from direct sunlight.
Safety and Toxicity:Please refer to the relevant product safety data (MSDS).
