I have researched the use of thermal coatings as a way to insulate the container and prevent condensation. There are a number of products available called ceramic coating, for example SuperTherm. SUPER THERM is a water-borne insulating coating that is specifically designed to block heat-load, moisture-penetration, and air-infiltration on virtually any type of surface. The thickness of a credit card equals the same R-value as 18 cm of traditional insulation. Its origin comes from NASA as a ceramic coating used on the space shuttle.
