Bayer MaterialScience has been awarded Bio-based Material of the Year 2015 for its bio-based hardener for polyurethane (PU) coatings and adhesives.

The product, based on pentamethylene diisocyanate (PDI), complements polyols made from renewable raw materials, which are already being used in polyurethane coatings and adhesives. These coatings can thus now be formulated entirely from bio-based components.

Some 70% large proportion of the carbon content the new Desmodur eco N 7300 hardener is biomass-based. The starting product is a starch from forage corn, a feed and industrial crop that is not intended for human consumption and does not compete directly with food production.

Bio-based materials

Commercial production of Desmodur eco N 7300 is due to begin following mandatory REACH registration. A total annual capacity of up to 20,000 metric tons is to be provided at existing plants for this purpose.

The technology was recognized at the International Conference on Bio-based Materials on April 13 in Cologne, Germany.
