Dimethyl Thio-Toluene Diamine E300

Dimethyl Thio-Toluene Diamine E300
Product Detailed
E300 1.Substitute of MOCA. 2.Used as curing agent and firming agent 3.Rich experience 4.High quality and low price


About the product

1.DMTDA is low viscosity liquid Curing agent,in which there are mainly two isomers,namely mixture of 2,4-and 2,6-dimethylthioaromatic diamine(the blend rate about 77~80/17~20).

2.DMTDA is Environmental Non Toxic curing agent.The traditional curing agent MOCA will be dropped out from marketplace for its high poisoness.

3.Property And Specification:

yellow to amber transparent liquid under normal temperature

Molecular Weight:214

Equivalent Weight:107


Amber Liquid                                                               


Slight Amine                                                                         

Boiling Point(1.68mmHg)








Vapour pressure(mmHg/20°C)                                                 





1.DMTDA is served as  Extender chain effect in the usage of polyurethane,coating,RIM,adhesive,etc.It is also epoxy resin firming agent.

2.DMTDA is widely used in auto,arvhitecture,metal mine,medicine and others.

3.DMTDA can be used in textile,papermaking and printing.

4.DMTDA is used in remove polyurethane glue.


1.DMTDA,being a liquid at room temperature results in significant processing adwantages,for examples,in such operation as transfer,melting down of solids is eliminated.Also,the possibility of freezign-up is no longer a concern during mixing or in meter-mixing machines.Additionally,its liquid state permits processing prepolymer at lower temperatures than that of MOCA

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