DMTDA Equivalent To Ethacure 300


1. Product Overview:


Dimethylthiotoulenediamine (DMTDA) is equivalent to Ethacure 300 (Albemarle). It is a liquid aromatic diamine with low chronic toxicity, is an effective curative for polyurethane cast elastomers.It is used in both hot and room-temperature casting. It can also be used as a slower chain extender for polyurethane urea and polyurea elastomers in reaction injection molding, structural reaction injection molding and hand-applied and spray coating applications, alone or in blends with DETDA curative.


2. Physical and chemical properties:


  • Appearance: Light yellowish liquid
  • Boiling point,():353
  • Density (g/cm3) @(20): 1.2
  • Pour point(): 4
  • Flash point():176
  • Viscosity,cps @ 20:690
  • Equivalent weight with isocyanates: 107
  • Equivalent weight with epoxy resins: 53.5

3. Quality standard:

  • Appearance: light yellowish liquid
  • Color value: 8
  • Diamine content(%): 99.0
  • Amine value(mgKOH/g): 525-535
  • Moisture(%): 0.1

4. Safety information:

  • Class: 9
  • Packing group: III
  • UN No.: 3082
  • EINECS NO.: 403-240-8

5. Packing size:

  • 25kg/steel drum
  • 200kg/steel drum
  • According to customer requirements, with special packaging

6. Considerations: 

  • To be nitrogen-sealed, if cannot be used as a packaging, should be subject to nitrogen-sealed storage.
  • Avoid outdoor exposure or long-term placement under high temperature conditions.
  • This product is in storage, preferably above 0 centigrade degree, can guarantee the same long-term quality.
  • Darkens with time and exposure to air.

7. Processing:


Ethacure 300 is a low viscosity liquid that is ready for immediate use. Loading can be accomplised with simple hand pumps or gravity feed. Dry nitrogen should be used to blanket curative tanks.


8. % Theory


Selection of 95% theory is generally recommended. Lowering it to 85% theory will improve compression set and raise 300% modulus (tensile). Increasing to 105% theory will enhance tear strength and elongation.


9. Mix ratio


The following equiation calculates the amount of Ethacure 300 required for 100parts (by weight) of prepolymer.


% NCO×2.55×%Theory=Ethacure 300pph


%Theory is expressed as a decimal, i.e. 95% Theory is 0.95 for the calculation.
