Finally, DOTG has a negative but insignificant effect on deficient bridges, which suggests that it does not matter that the governor directly appoints the head of the DOT.
All variables with the exception of GROWTH, VMT, INITIATIVE, and DOTG are of the same signs and significance as in Table 2.
Certain high temperature acrylate and ethylene-acrylate rubber compounds (HT-ACM and AEM) are processed using the vulcanisation accelerator DOTG
(3.) "Formulation suggestions for replacing DOTG
in AEM compounds," E.
For many years, DOTG was used as the primary accelerator for AEM compounds because it provided fast cure speeds and low compression set.
Many different accelerators have been evaluated as replacements for DOTG, but none has the same combination of fast cure speed and low compression set.
This benefit is important for compounds that cannot use DOTG as the accelerator.
Table 3 shows an AEM GLS compound with DOTG as an accelerator compared to AEM GLS and AEM 3110 compounds with a DBU based accelerator.
The situation with respect to DOTG is changing, and this is discussed in more detail in other presentations, including reference 3.
It was difficult to find an accelerator that worked as well as DOTG as far as speeding up the cure rate and improving the compression set.
The European Union under REACH is going to ban the use of guanidine curatives such as DPG and DOTG
. Either DOTG
or a combination of DOTG
with DPG is used with either HMDA or HMDC.
Why replace DOTG
? Studies have shown that, when used with other curatives, DOTG
can produce o-toluidine.
