Biobased Pentamethylene Diisocyanate (PDI)
September 16 │ CAS EMEA/LATAM 5
A new building block for polyurethane chemistry
• The first isocyanate with significant biocontent: 71% renewable carbon*
• Produced very efficiently from biomass combining biotechnological and chemical processes, e.g. energy efficient gas phase technology
• First diisocyanate in 30 years to be fully developed and scaled-up
• The corresponding derivatives are similar to hexamethylene diisocyanate (HDI) based ones, yet offer some advantages
High performance enabled by nature * Confirmed by radiocarbon method 14C measurement according to ASTM-D6866 standard
High performance enabled by nature
September 16 │ CAS EMEA/LATAM 6
The first biobased polyurethane crosslinker
• DESMODUR® eco N 7300: first PDI derivative launched April 2015 at the European Coatings Show
• Full REACH registration to be completed in 2016
• Development of technology platform based on PDI
• Innovation multi-awarded:
