Basic Rubber Accelerator DCBS CAS NO 4979-32-2

N,N-Dicyclohexyl-2-benzothiazolsulfene amide

C₁₉H₂₆N₂S₂

M.W. 346.55

CAS No.: 4979-32-2

EINECS No.: 225-625-8

PROPERTIES:

Compared with CBS, TBBS, MBS,DCBS scorch time and curing time is long, modulus of vulcanized rubber is low. The homologous physical properties to obtain need higher dosage.  to increase the amound to obtain the corresponding properties. Usually used in the steel wire rubber formula to improve the bonding strength. DCBS can delay scoring, improve process safety. DCBS-80 can make the rubber compound with long scorching, safety processing and high curing speed. It can be used alone in the low sulphur vulcanization, also can be used together with dithiocarbamate salts or thiuram accelerators, the vulcanizates has good aging resistance and compression set resistance. 

Dosage:
