Dimethylthio Tolune Diamine(DMTDA)-E300
1.Introduction
Dimethylthio Tolene
Diamine(DMTDA)-E300 is equal to Ethancure 300. It is a very effective chain extender of polyurethane elastomer, in particular for RIM (reaction injection molding) and SPUA
(Spray Polyurea Elastomer). Moreover, it can also be used as curing agent of polyurethane and
epoxy resin , antioxidant of epoxy resin, industrial oil and lubricants. In addition,it can also serve as
intermediates in organic synthesis.

3.Uses: DMTDA
is a kind of new polyurethane elastomer curing
agent.
4.Processing:E-300,
being a liquid at room temperature results in
significant processing
advantages, for example, in such operation 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, its liquid state permits processing
prepolymer at lower temperatures than that of
MOCA.
E-300 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.
