Desmodur W is also known as PICM, hydrogenated MDI (HMDI or H12MDI), saturated MDI (SMDI), reduced MDI (RMDI), and dicyclohexylmethane diisocyanate. Desmodur W diisocyanate is useful as a reactive building block for the preparation of chemical products, reactive intermediates and polymers.

Desmodur W diisocyanate is especially useful as an organic intermediate because the isocyanate groups can undergo addition reactions at room temperature with compounds which contain active hydrogens.

  • Polyurethane resins based on Desmodur W diisocyanate have a high degree of flexibility coupled with good mechanical strength. They are resistant to abrasion and hydrolysis and retain gloss and physical properties upon weathering.
  • A unique feature of Desmodur W diisocyanate is its ability to form optically clear polyurethanes when combined with suitable polyol co-reactants.
  • As with any product, use of Desmodur W in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
