Anti-fog films are films with proprietary agent that keeps any product free from condensation or grease. These are modified films that have high affinity for water. The condensed water forms a continuous thin layer of water over the entire surface. The film should be installed so that water can flow without interruption down to the edge of the film.
Working of anti fog films Due to anti-fog films, water is able to drain more evenly and flow to the lowest point. Water may even be able to flow over wrinkles that would normally be a prime location for dripping. It reduces number of spots where dripping occurs. Thin layer of water also acts as an infrared absorber.
