To address the rising demand for environmentally compatible coatings and adhesives in the Asia-Pacific region, Covestro is planning a new production facility for polyurethane dispersions (PUDs) at the Covestro Integrated Site in Shanghai, China.


A further line for polyester resins, from which PUDs are produced, is also to be built there. The plants are due to be completed in 2024.

“In the future, customers will continue to rely on replacing solvent-based products with more sustainable waterborne systems with equally good properties. Thanks to our versatile production, we are at the same time flexible and can satisfy many different requirements,” says Michael Friede, Global Head of the Coatings, Adhesives, Specialties segment at Covestro.


The areas of application for PUDs are highly diversified. For instance, Covestro raw materials from the Bayhydrol UH, U and UV series and Bayhytherm are used in basecoats for automotive primary and refinish coatings, as well as in wood and furniture coatings and robust floor coatings.

PUDs are used in many applications, including UV-curable gloss and matte floor coatings. 


Adhesives formulated with Dispercoll U are used in furniture and shoe manufacturing as well as in the automotive industry.


The low-solvent components also play an important role in the production of coated textiles and fiber-reinforced plastics.
