Stained Natural Synthetic Rubber Accelerator BZ ZDBC-80

Stained Natural Synthetic Rubber Accelerator BZ ZDBC-80

Zinc dibutyldithiocarbamate
C18H38N2S4Zn
M.W.: 476.14
CAS: 136-23-2
EINECS: 205-232-8

PROPERTIES:
    ZDBC is an ultrafast accelerator of natural and synthetic rubber such as EPDM, SBR, NBR. Thiurams and thiazoles accelerator can lower curing rate and improve processing safety. Compared to ZDEC, ZEPC and ZDMC, ZDBC has a shorter scorching time and longer curing time. A little ZDBC is also a assistant accelerator of thiols or thiurams accelerator. Its vulcanizate has excellent tensile strength and resilience.Heat resistance in NR and IR can be improved by using together with antioxidant. 

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.

TYPICAL VALUES:
Initial melting point: 104℃
Purity: Min 97%
Zinc content: 13.0-15.0%
Heat loss: Max 0.5%
63μm sieve residue: Max 0.5%

Compared to traditional ZDBC powder, Actmix ZDBC-80GE/C allows:
Dust free products with a complete filtration up to 100µm, no skin sensitization, health guard of operators.
Effective guarantee of activity of ZDBC due to pre-dispersed masterbatch.
Tack free products at room temperature, convenience and accuracy on ingredients.
Lower Mooney viscosity at lower temperature (50℃), higher quality of dispersion.
Impurity free, blocked filter free of extrusive products, scrap rate reduction and higher productivity thanks to filtration.
Wider compatibility with other elastomers.
