For NR: 0.8-1.2phr with 2.5-4phr sulfur;
For SBR: 0.1-0.4phr with 1-1.5 thiols and 1.5-2.5phr sulfur;
For NBR: 0.05-0.4phr with 0.8-1.5 sulfenamides and 1.5-2.4 sulfur.
DOTG can lead to a very slow start of vulcanization and relatively slow vulcanization rate. Combination
with effective antioxidants is necessary due to serious vulcanizing reversion when DOTG is used alone.
Combination with thiols, sulfenamides, thiurams and dithiocarbamates can lead to synergistic and secondary
accelerating effects: improvement of cross-linking density and vulcanization rate, excellent mechanical and
anti-aging properties of vulcanizates. It will be non-blooming in vulcanizates.
