Polyols with a track record of success

Desmophen®: world-renowned polyurethane polyol building blocks

Polyurethanes consist of two main components – polyols and polyisocyanates. Through careful selection of each raw material, an endless array of polyurethanes (PU) with wide-ranging properties is possible. Desmophen® polyols from Covestro are proven as high-quality building blocks for PU coatings.

For more than 70 years we have been developing and manufacturing Desmophen® polyols for high-performance coatings.

Desmophen® polyols are used for the formulation of solventborne, high solids, two-component (2K) polyurethane and polyurea formulations. They are also used for the preparation of one-component (1K) systems.

The Desmophen® line includes:

  • Polyethers
  • Polyesters
  • Polycarbonates
  • Polyaspartics

Polyurethanes based on Desmophen® polyols, particularly when reacted with Desmodur® crosslinkers, are fast drying, durable and elastic coatings with excellent resistance to chemicals, physical influences, weather and UV radiation.

These polyurethane coating systems have a broad range of applications:

  • Automotive OEM finishes
  • Transportation coatings
  • Industrial coatings
  • Plastic coatings
  • Can/coil coatings
  • Corrosion protection
  • Wood and furniture finishes
  • Structural protection
  • Floor coatings
  • Roof membranes
