Desmophen® polyols for highly resistant adhesives and sealants

Due to the range of properties that can be achieved using polyurethanes and polyureas, adhesives based on these technologies are finding increasing use in a widening array of applications. Covestro is helping adhesive formulators leverage these opportunities with extensive polyol and isocyanate chemistries.

For more than 75 years, we have been developing and manufacturing Desmophen® polyols for the formulation of solventborne – and high solids – two-component (2K) polyurethane and polyurea adhesives and sealants.

The Desmophen® line includes:

  • Polyethers
  • Polyesters
  • Polycarbonates (Desmophen® C)
  • Polyaspartics (Desmophen® NH for polyureas)

Polyurethanes based on Desmophen® polyols, particularly when reacted with Desmodur® polyisocyanate crosslinkers, are ideally suited for use in adhesives for flexible packaging, sealants and hot melts.

With primary and/or secondary hydroxyl or amine groups, Desmophen® polyols form fast-drying, durable and elastic adhesives and sealants. They offer excellent resistance to chemicals, physical influences, weather and UV radiation.

Desmophen® polyester polyols are also suitable for the formulation of prepolymers used to prepare polyurethane and polyurea adhesives and sealants.

With our wide range of high-quality Desmophen® polyol chemistries, formulators can access polyols with properties they need for advanced adhesive and sealant applications.
