APPLICATION:
Super accelerator TDEC-75 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-75 have high tensile strength, and good aging resistance. Additions of TDEC-75 are advantageous in soft compounds with a high oil content, since larger dosages of oil reduce the curing rate.
DOSAGE:
Max 0.5phr to avoid blooming.
PACKING & STORAGE:
Net weight 25kg/carton lined PE bag; Net 600 kg/pallet.
