Covestro to Lower Residual Monomer Content of Free Monomeric Diisocyanates

Published on 2017-12-11. Author : SpecialChem

Responsible handling of chemical substances has always been necessary for avoiding health risks. This also holds true for isocyanate processing. Covestro is committed to continually improving the performance and safety of its products, and above all, to setting new standards in industrial hygiene.


Addition of “ultra”

Through continual improvements to the manufacturing process, Covestro has succeeded in reducing the residual monomer content of free monomeric diisocyanates to under 0.1 percent by weight. Products meeting these requirements can be recognized by the addition of “ultra” to the product designation.

In the coming months Covestro wants to offer raw materials for solvent-based and solvent-free products (Desmodur® ultra) as well as for aqueous coatings and adhesives (Bayhydur® ultra), thereby replacing a significant proportion of the previous product portfolio. Further products should be added to the ultra-line in the near future.

New standards in Industrial Hygiene

Michael Friede, Global Head of the Coatings, Adhesives, Specialties segment at Covestro:

“With the new ultra-products, in combination with the application of the usual safety measures, we are setting new standards for our customers in industrial hygiene. As a result, the new product line’s raw materials match the performance level of our conventional products.”
