Purac, a leading player in natural food preservation and bio-based building blocks and chemicals, and Perstorp, a leading specialty chemicals company, today announced a research and business development partnership for caprolactone lactide co-product for the coatings, adhesives and other markets.

Possible uses for the new products are polyols for coatings, adhesives, sealants and elastomers, and as hot-melt adhesives. The unique composition makes it possible to control both the melting point and mechanical properties, and reduce the crystallinity of polyols.

“We look forward to our cooperation with Perstorp. Our first jointly developed caprolactone lactide co-products show that the modification of existing resins with bio-based PURALACT^® lactide adds value to the value chain by combining increased sustainability with enhanced performance”, according to Vice President Chemical & Pharma, Marco Bootz.

“We are very excited about this strategic partnership with Purac, which has a strong position in bio-based products for a broad range of industries. With Perstorp’s strong position in specialty products for coatings and plastics, our respective skills and experience comprise a good foundation for a successful research and business development, and means that we are expanding our Capa™ range with partly renewable products,” says Market Development Director, Håkan Björnberg.

 The new caprolactone lactide co-products will be launched to the market by Perstorp during 2013 and presented both at K-fair and at the European Coatings Show. A number of lead customers have already been supplied with the new co-resins and have approved these in their final products.
