ustainability is increasingly impacting on the purchasing decisions of customers, brand owners and consumers. Therefore,
Covestro has early decided to embark into bio-based materials and thus to develop a new bio-based diisocyanate, namely
the pentamethylene diisocyanate (PDI). This is the first diisocyanate with a significant renewable content based on a raw
material produced via a highly efficient fermentation process directly from biomass. Utilizing the cost and energy effective gas
phase technology to produce the isocyanate results in a highly sustainable product with 70% bio-based content and double
digit reduction of carbon foot print equivalent. Based on this new building block Covestro launched in 2015 the first bio-
based polyisocyanate Desmodur® eco N 7300, a new solvent-free aliphatic polyisocyanate which is able to match the high
performance requirements of automotive OEM coatings. In 2017 a further milestone has been achieved: the development of
hydrophilic PDI-based polyisocyanate - the Bayhydur® eco 7190, will allow the formulation of 2K waterborne polyurethane
coatings with increased renewable content and lower VOC. Both new developments allow increasing renewable content of
solvent-borne and water-borne high performance polyurethane systems with low carbon footprint, satisfying current and
future requirements from the coatings market. Covestro would like to provide the audience with a brief overview about our
experiences with the launch of these new bio-based polyisocyanates.
