APPLICATION:
ZDBC-80 is a ultra-accelerator for natural rubber and synthetic rubber. In case of blooming,it always use together with other dithiocarbamates and keep the dosage under 1 phr. It's also a good activator for thiazoles accelerators and very suitable for high-clarity products.
DOSAGE:
For NR: 0.6-1.0phr; As a secondary accelerator: 0.1-0.2phr.
For SBR/NBR: 0.6-1.2phr. As a secondary accelerator:0.1-0.2phr.
For EPDM: 1.5-2.5phr
