Dow’s can coating formulations gain recognition
Dow Coating Materials has been recognised at the Edison Awards for Applied Technology for its innovative approach to can coating formulations.
Dow’s Canvera Polyolefin Dispersions offer a water-based, spray-applied replacement for incumbent epoxy coating systems, eliminating presence of BPA and delivering brand owners a new approach to sustainable can coating that will appeal to health conscious consumers.
Powered by patented Bluewave Technology which facilitates creation of ultra-thin, thermoplastic film coatings, Canvera Polyolefin Dispersions can be spray-applied from water-based formulations to the inside of cans, protecting contents from changes in colour, taste or appearance. The innovation complies with applicable food contact regulations in the US, Europe and China.
Jan Weernink, global marketing director for metal packaging, said: “One of the key advantages is that the starting point for Polyolefin Dispersions is polymeric, which minimises the need for any cross-linkers.This gives a viable, long term alternative to solutions based on epoxy monomer, which relies heavily on processing materials which are coming under health scrutiny and regulatory pressure.
“In short, it means coatings manufacturers can move away from materials of concern in their formulations, and offer progressive brand owners and retailers a sustainable approach that can deliver superior food safety profiles from the packaging systems they use.”
Canvera Polyolefin Dispersion Technology can be used on existing production lines and applied directly to metal surfaces by the same equipment used for current epoxy coatings, facilitating enabling drop-in performance and seamless manufacturing productivity.
The next generation can coating option solution even offers flexibility in base polymer choice to match specific applications, adhesion to a variety of substrates, as well as durability and chemical resistance.
