Actmix® Accelerant DOTG-75
Accelerant DOTG
Active ingredients |
1,3-di-O-tolylguanidine
Molecular Formula: C15H17N3
Molecular Weight: 239.32
CAS RN: 97-39-2
EIENCS RN: 202-577-6 |
Properties:
DOTG can cause slow curing speed and thus should be used together with anti-aging agent. DOTG has no crocking in vulcanized rubbers.
NR: 0.8~1.2 poses and 2.5~4 poses sulphur used together
SBR: 0.1~0.4 poses and 1~1.5 poses thiol and 1.5~2.5 poses used together with sulphur
NBR: 0.05~0.4phr and 0.8~1.5phr sulfenamide Accelerant and 1.5~2.4phrused together with sulphur.

Compared with traditional powdered DOTG, Actmix® DOTG-75 has the following advantages:
Raw materials 38µm are all under sifting, but no dust appears with master batch
master batch DOTG-75 is pre-dispersed with rubber carrier, thus can effectively ensure the activity of DOTG.
No clay domain appears with master batch at room temperature
Has low Mooney viscosity at low temperature such as 50°C to improve disperse quality
While granulation, master batch can filtering to lower rejection rate.
Has good compatibility with different rubbers |
