With the wet baking method, there will be water under the automobile solar film, which absorbs heat when heating the automobile solar film, and the automobile solar film with curvature will arch one by one. When baking with a hot air gun, the arched and flat parts of the automobile solar film will be heated unevenly, and too much heat will lead to broken glass.

Dry baking is an original and up-to-date baking method of automobile solar film, that is, anhydrous baking film forming method. In this way, the formed automobile solar film can conform to the radian of glass more accurately. The principle is that air is used to replace the water between the automobile solar film and the glass, and fossil powder is used to ensure that the scratch-proof layer "SR" of the automobile solar film will not be adsorbed on the glass due to electrostatic action, so that the automobile solar film can fully slide freely on the glass.

Dry baking has its unique advantages: it is fast, and it usually takes more than ten minutes to dry bake, while it can be baked in about 2-3 minutes; He is safer and more obedient, and the solar film of the car shrinks more evenly.
