Purac, Perstorp sign partnership for caprolactone lactide development

In the Netherlands, Purac and Perstorp announced a research and business development partnership for caprolactone lactide co-product, for amongst others coatings and adhesive markets. Combining the complementary strengths of Purac in renewable lactic acid based chemicals and Perstorp in specialty products for coatings and plastics has already resulted in partly renewable caprolactone lactide co-products. Possible uses for these new caprolactone lactide co-products are, amongst others, as polyols for coatings, adhesives, sealants and elastomers and as hot-melt adhesives. Its unique composition makes it possible to control both the melting point and mechanical properties and reduce the crystallinity of polyols.

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.
