A team of researchers at the Fraunhofer Institute for Applied Polymer Research IAP, along with the Fraunhofer Institute for Manufacturing Engineering and Automation IPA, are working on developing a cost-effective coating based on renewable raw materials. The solution findings are reportedly in starch esters that are dispersible in water, form continuous films and have good adhesive properties on both glass and aluminum surfaces.
Tests are being done to check the long-term performance of the coated materials by exposing them to rapidly changing temperatures in a time-compressed form. These tests were designed to mimic the day/night cycle and the seasons. Test objects are also reportedly exposed to electrolyte-enriched water to see how the coating reacts to water.
