Application: DPG can be used for NR, IR, SBR, NBR and CR. Very useful basic accelerator thatcan be used in combination with acidic accelerators, very seldom used alone. It can be used with MBT, MBTS, CBS, MOR, TMTD, TETD, TMTM, ZDMC, ZDEC, ZDBC, ZEPC and others. Used as secondary accelerator with thiazoles and sulphenamides in NR and SBR compounds, giving good physical properties. Better storage stability compared to thiurams and dithiocarbamates, but not as active. As it has a bitter taste, it cannot be used for products in contact for foodstuff.

Storage: To keep the bags tightly closed in a cool, well-ventilated place at 25℃ max, to place the goods on the dry wooden shelf at a height of 20cm min. And to avoid from moisture, sunshine, light and fires. The recommended max.shelf life is two years.

Package: 25kg or 20kg paper bag or PP weaved bag lined with plastic bag.
