Application:A medium fast primary accelerator suitable for NR, IR, SBR, NBR, HR and EPDM. An outstanding delayed action accelerator. Be top effective and safe when used at ordinary processing temperatures, causing no scorches. Vulcanized show excellent physical property and quick complete. Usually used alone when activated by WILLING DPG, WILLING TMTD and WILLING TS.

Packaging:25kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo 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 validity is 1 year.

Properties

It is a highly active aftereffect accelerator with excellent scorch resistance, safe processing and short vulcanization time. When the vulcanization temperature is above 138 ℃, the promoting effect is very strong. Often cooperate with TMTD or other basic accelerators to form a second accelerator. Alkaline accelerators such as thiuram and disulfide carbamates can enhance their activity. It is mainly used for manufacturing industrial rubber products such as tires, rubber hoses, rubber shoes and cables.
