Beverages, when served cold, quickly heat up during consumption. A client seeks material and process technologies that will insulate against heat gain or actively reduce temperature of liquids contained in glass bottles or metal cans. Processes that enable the printing, coating, and spraying of foam-like or phase-change materials are also of interest. Potential solution areas include insulation materials, aerogels, cooling hydrogels, and foaming polymers. The material must not be more than 250 microns thick.
