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.
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:
• Polycarbonates (Desmophen C)
• Polyaspartics (Desmophen NH for polyureas)
Polyurethanes based on Desmophen polyols, particularly when reacted with Desmodur crosslinkers, are fast drying, durable and adhesives, sealants, and coatings, with excellent resistance to chemicals, physical influences, weather and UV radiation.
