Wet baking method has many disadvantages, such as long installation time, difficult to set large arc, easy to produce scratches and folds when squeezing water, and easy to cause glass explosion accidents. How can the glass burst? Because the windshield curvature of some cars is relatively large, there will be water under the film during wet baking. When films are heated, water will absorb heat, and films with curvature will arch one by one. When baking with a hot gun, the arched part and the flat part will be heated unevenly, and too much heat will cause the glass to break.

Dry baking is an original and latest baking method, that is, anhydrous baking. This method can make the molded window film conform to the radian of glass more accurately. The principle is that air is used to replace the water between the window film and the glass, and fossil powder is used to ensure that the scratch-resistant layer "SR" of the window film will not be adsorbed on the glass due to electrostatic action, so that the film can slide freely on the glass. Dry baking has its unique advantages: it is fast, generally, wet baking takes more than ten minutes, and dry baking can be done in about 2-3 minutes; Safer, more docile, the shrinkage of the film is more uniform, the area with large curvature can be baked well, and the glass is not explosive; It is more convenient to install and paste, and bubbles often appear in wet baking at the heating wire, which can be completely avoided in dry baking.
