Covestro Reduces Monomer Content of Free Monomeric Diisocyanates

Published on 2017-12-11. Author : SpecialChem


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.

Improvements to the Manufacturing Process

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.

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,” says Michael Friede, Global Head of the Coatings, Adhesives, Specialties segment at Covestro. “As a result, the new product line’s raw materials match the performance level of our conventional products.
