You can see condensation at work in the supermarket when you open the door of a refrigerated case. Warm air from outside the case rushes in and quickly fogs the glass, making it difficult to see inside the case once you close the door. Refrigerated cases have built in heaters that evaporate condensation off of the interior glass surface. Having a heater inside a refrigerator is a little counterintuitive. It’s also expensive.
By itself, refrigeration is expensive. Currently, the typical household refrigerator consumes more energy over the course of a year than any other electrical appliance. People spend more on refrigeration than they spend on heat! Commercial refrigerators are even more expensive, so adding heat to the refrigerator in order to combat condensation simply increases the cost of refrigeration.
By eliminating condensation inside the refrigerator quickly and without added heat, retailers can reduce the cost of refrigeration. What’s the secret? A super-hydrophobic thin-film acetate coating applied to the interior glass surface repels water so it drains away immediately, without the need for heaters inside the refrigerator case.
According to the manufacturer, retailers could save about $85 per year per standard refrigerator case. At that level, the film could pay for itself through reduced energy consumption in less than 2.5 years.
Coatings can allow glass to do some pretty amazing things! For example, Glassprimer™ glass paint is a specially engineered glass coating that creates a permanent bond with glass surfaces. Glassprimer™ glass paint can be tinted to match any major paint manufacturer’s paint palette. That means you can easily incorporate painted glass into any decorating scheme. Whether your project is completely interior, completely exterior or a bit of both, Glassprimer™ glass paint offers exceptional durability, UV resistance and versatility.
