Super accelerator TDEC for NR and synthetic rubbers. It causes a high spped vulcanization of EPDM and IIR when used together with other accelerators of the thiazole, thiuram and dithiocarbamate class. Even used in small amounts of TDEC-75, it gives a shorter total curing time. The vulcanizates using TDEC have high tensile strength, and good aging resistance. Additions of TDEC are advantageous in soft compounds with a high oil content, since larger dosages of oil reduce the curing rate.

Package: 25kg plastic woven bag, paper with plastic film bag, paper bag.

Storage: The product should be stored in the dry and cooling place with good ventilation, avoid direct sunlight. Since the date of production, the storage period is 12 months.
