Analysis Methods

  1. Molecular weight
    • SP series : Number average molecular weight (Mn) by ebullioscopic method
    • P series : Number average molecular weight (Mn) by osmotic pressure method
  2. Amine value : Acidimetry in non-aqueous system
  3. Decomposition temperature : Differential
  4. Flash point : Cleveland open tester
  5. Amine Ratio: NMR (13C)

Viscosity Properties

The viscosity of EPOMIN™ greatly varies depending on its molecular weight, temperature and concentration when diluted in water.
The graphs below show the relationship between temperature vs. viscosity and concentration vs. viscosity.
