This product is white powder, taste bitter, odorless. Relative density: 1.01-1.02, soluble in chloroform, acetone, ethanol, slightly soluble in benzene, insoluble in water and gasoline.
Can be activated with accelerator D (diphenyl muscle) is very similar. At the temperature of operation activity is very small, the operation is very safe. The critical curing temperature of 141 DEG C, in particular the vulcanization temperature is higher than the critical temperature is very active, and better curing flatness. This product is acidic promoter, especially thiazole, an active agent sulphenamides accelerator, and accelerator M with ultra accelerator effect. Mainly used for thick wall products, tread rubber, buffer layer, covering rubber rollers. The first accelerator dosage is 0.8-1.5, the second promoter as thiazoles dosage is 0.1-0.5.
