4. Properties:

DPG can lead to a very slow start of vulcanization and relatively slow vulcanization rate but can not be applied to light-colored products due to its ability of slight discoloration except for activator. Combination with effective antioxidants is necessary due to poor resistance of thermo-oxidation ageing of vulcanizate when DOTG is used alone. DPG can effectively activate thiols accelerators but has no accelerating effect on vulcanization of IIR and EPDM.

5. Dosage:

Primary accelerator: 1-2phr with 2.5-3.5phr sulfur;

Secondary accelerator: 0.1-0.25phr with 0.75-1 thiols accelerators and 2.5phr sulfur.
