When applying PU - adhesive PET protective films on curved glass, bubbles can be a frustrating issue. However, with proper techniques and high - quality products like those from Shenzhen Everbright Far Film Co., Ltd., this problem can be minimized.
Everbright Far, a leading manufacturer in the surface protection adhesive products industry, offers a range of high - performance PET protective films. Their products are known for their excellent adhesion properties. To avoid bubbles, start with a clean surface. Ensure the curved glass is free from dust, oil, and fingerprints. Use a lint - free cloth and a suitable glass cleaner.
When applying the film, work slowly. Begin from one edge of the glass and gradually lay the film, smoothing it out as you go. The PU adhesive in Everbright Far's films has good flowability, which helps in reducing air entrapment. If you notice any small bubbles, use a soft squeegee to gently push them towards the edge of the film.
These protective films are widely used in various industries such as electronics (for smartphone and tablet curved screens), aerospace (for protecting curved glass components), and automotive (for curved windshields). With Everbright Far's products and the right application methods, you can achieve a bubble - free and long - lasting protection for your curved glass.
