Commercial Products Desmodur®/Desmophen®
This brochure provides an overview of the commercial products from our Desmodur®/Desmophen® range with their key technical data and applications.
The information covers aliphatic and aromatic poly- isocyanates (Desmodur®), polyacrylate, polyester and polyether polyols (Desmophen®) as co-reactants for polyisocyanates in 2K-PUR systems, the products from the Desmocap®, Desmolac® and Desmotherm® families, and specialities.
In addition to the Desmodur®/Desmophen® products, Bayer MaterialScience markets the Bayhydrol®/ Bayhydur® and Roskydal® ranges. Bayer Material- Science – one of the world’s leading producers of coat- ing raw materials – therefore possesses a comprehen- sive portfolio of high-grade building blocks for polyurethane coating systems.
Coating raw materials from Bayer MaterialScience meet the many requirements of the coatings industry and are used in a wide variety of applications. These include automotive OEM finishing, transportation coating, automotive refinishing, industrial coating, plastics coating, corrosion protection, wood and furniture finishing, structural protection, floor coatings and roof membranes.

Basic chemical reactions
Film formation in classic two-pack coatings is This reaction occurs if the base products are largely the result of addition reactions multifunctional, i.e. each molecule contains between the isocyanate groups of the poly- at least two isocyanate or hydroxyl groups. isocyanate and the hydroxyl groups of the For a film to form, wich requires three-dimen- polyol compound to form substituted sional crosslinking, at least one of the co- polyurethanes. reactants should have three or more func- tional groups in the molecule. Isocyanate groups may also react in a similar H way with other compounds containing I reactive hydrogen atoms, e.g. with amino and [1] R–N=C=O+R’–OH R–N–C=O imino compounds, carboxyl groups or, simplest I O–R’ of all, water.
In the case of moisture-curing one-pack stable carbamic acid and splits off carbon di- systems, the polyisocyanates cure through oxide. The amino groups react directly with the reaction of free isocyanates with water in isocyanates to form urea, as shown by the the form of atmospheric humidity.
