To achieve this, Dimethylthiotoluenediamine (DMTDA) should be used in place of MOCA at the appropriate ratio.

*Curing Behavior
Dimethylthiotoluenediamine (DMTDA) influences the physical properties of cured polyurethane elastomers.
The prepolymer can be either polyester or polyether type.

Dimethylthiotoluenediamine (DMTDA)-cured systems can be compared with MOCA-cured ones.
As with MOCA curing systems, the physical properties of the cured polymer are sensitive to the ideal ratio.

Dimethylthiotoluenediamine (DMTDA) curing agents exhibit acceptable stoichiometric deviation.
Low stoichiometry (80–90%) usually helps achieve maximum resistance to permanent deformation and compression set.

High stoichiometry (100–105%) helps achieve maximum tear strength and fatigue life.
For best results in most uses, 95% of the ideal ratio is recommended.

Dimethylthiotoluenediamine (DMTDA) curing conditions (temperature and time) are similar to MOCA.
However, more emphasis is needed on secondary vulcanization conditions with Dimethylthiotoluenediamine (DMTDA).
This is essential to obtain optimum physical properties, particularly compression set and dynamic mechanical properties.

PROCESSING OF DIMETHYLTHIOTOLUENEDIAMINE (DMTDA):
Dimethylthiotoluenediamine (DMTDA) is a liquid at room temperature.
This results in significant processing advantages.
For example, in such operations as transfer, melting down of solids is eliminated.

Also, the possibility of freezing-up is no longer a concern during mixing or in meter-mixing machines.
Additionally, Dimethylthiotoluenediamine (DMTDA)'s liquid state permits processing prepolymer at lower temperatures than that of MOCA.

PERFORMANCE & FEATURES OF DIMETHYLTHIOTOLUENEDIAMINE (DMTDA):
Dimethylthiotoluenediamine (DMTDA) is used as a PU curing agent.
Dimethylthiotoluenediamine (DMTDA) can slow down the activity of "NH2" group, thus extending the pot life while casting.

Dimethylthiotoluenediamine (DMTDA), being a liquid at room temperature, results in a significant processing advantage in comparison to MOCA.
Melting down of solids is unnecessary.

Dimethylthiotoluenediamine (DMTDA)'s liquid form allows the processing of prepolymer at a lower temperature than that of MOCA.
There is no solidification during the mixing.

Dimethylthiotoluenediamine (DMTDA) has an equivalent weight of 107 compared to 133.5 of MOCA.
This means that about 20% less by weight is required for a given prepolymer at the same stoichiometry.

COMPARING OF PHYSICAL PROPERTIES OF PREPOLYMER CURED WITH DIMETHYLTHIOTOLUENEDIAMINE (DMTDA) & MOCA
The physical properties of prepolymer, both ether and ester types, when cured with Dimethylthiotoluenediamine (DMTDA) curing agent, are comparable to those based with MOCA.

As in MOCA curing systems, physical properties are sensitive to the ratio (stoichiometry) of curative to prepolymer.
Dimethylthiotoluenediamine (DMTDA) curative exhibits tolerance to stoichiometry variations similar to that of MOCA.

Low stoichiometry (80~90%) generally tends to maximize compression set resistance.
High stoichiometry (100-105%) tends to maximize tear strength and flex life.
The best results for most applications are obtained at about 95% stoichiometry.

While cure conditions (temperature and times) are similar to those used with MOCA, Dimethylthiotoluenediamine (DMTDA) curative requires closer attention to post-cure conditions.
This is needed to obtain maximum physical properties, particularly for compression set and dynamic properties.

PHYSICAL PROPERTIES OF PREPOLYMER CURED WITH DIMETHYLTHIOTOLUENEDIAMINE (DMTDA) CURATIVE:
The specific gravity of Dimethylthiotoluenediamine (DMTDA) is about 1.20 g/cc at recommended use temperatures of 70–90℉ (21–33℃).
The specific gravity of molten MOCA at its use temperature of 240℉ (116℃) is 1.26.

This means that weight delivery by volumetric pumps is comparable for the two materials.
Therefore, if no alterations are made for meter-mixing machines, we must change the formula weight of MOCA into that of Dimethylthiotoluenediamine (DMTDA).
