AkzoNobel Functional Chemicals (Amersfoort, The Netherlands and Chicago, Ill.) held a press conference at JEC to announce its new BluCure umbrella brand, in partnership with DSM Composite Resins (Zwolle, The Netherlands), that encompasses sustainable products for cobalt-free curing. This novel approach aims to eliminate cobalt octoate — the main ingredient used in accelerators for curing unsaturated polyesters and vinyl esters — which the companies believe will be deemed hazardous in the near future. BluCure products, based on copper, manganese and iron, include cobalt-free preaccelerated resins and ready-to-use cobalt-free accelerators that enable fabricators to dose their own resins. According to the company, the new accelerators (used in place of legacy products) will maintain a fabricator’s existing cycle times and mechanical properties. BluCure accelerators will be licensed to resin producers or fabricators, and a “BluCure” seal will indicate a product or part made with the cobalt-free technology.
