HEERLEN, The Netherlands – Royal DSM N.V., Heerlen, the Netherlands, and Novomer Inc., Waltham, MA, have signed an agreement to jointly develop a coating resin using carbon dioxide (CO2) as a raw material.
This development agreement follows a cooperation agreement and an investment by DSM Venturing in Novomer in 2007. The project will benefit from the broad variety of DSM’s technologies and market access in combination with the efficient CO2 polymerization technology of Novomer.
The chemistry and process technology for producing polymers from CO2 and propylene oxide (PO) will be developed by Novomer, while DSM will convert the polymers into resins and formulate them for target applications such as coatings, adhesives and graphic arts. Initial results are encouraging and suggest that this project might lead to completely new and improved application properties in coatings.
Given the fact that up to 50 percent by weight of CO2 is used as raw material, the production of these resins will result in an improved carbon footprint. The process is also expected to be highly efficient, enabling the replacement of conventional resins in a number of coating applications.
Polycarbonate resins are widely known because of their superior performance and resistances and theoretically could find use in many types of coatings. However, commercial use of conventional types has always been limited due to their cost position and some weaknesses that are inherent in these products. The new CO2-based aliphatic polycarbonates to be developed by DSM and Novomer could potentially resolve these weaknesses.
