Mondur® polyisocyanates for high-performance polyurethanes

Polyisocyanates are one of the most important building blocks to create high-performance polyurethane materials. Mondur® from Covestro is a proven, high-quality polyisocyanate backed by decades of research and development.

A wide range of polyurethane-based coating formulations are possible with the right selection of polyols and isocyanates for use in coatings, sealants, adhesives, foams and plastics.

Since the 1940s, we’ve been developing the highest performing materials based on isocyanates. Our comprehensive range of Mondur® isocyanates for solventborne and high solids flexible, elastomeric polyurethanes, as well as adhesives and sealants, offers tremendous formulating freedom.

The Mondur® product line includes aromatic monomeric and polyisocyanates for the formulation two-component (2K) polyurethane systems. Our isocyanate chemistries include:

  • Diphenylmethane diisocyanate (MDI) 
  • Toluene diisocyanate (TDI)
  • Blends of MDI and TDI

Features of Mondur® polyisocyanates include low vapor pressure, low viscosity and good flowability. Formulators count on the proven performance of Mondur® isocyanate chemistry for diverse applications.
