PE protective film adhesion issues can arise due to several factors. Low polyurethane resin viscosity in the film, insufficient pressure during post-mold film pressing, or a dirty profile surface with dust or spray paint can all reduce adhesion.
To address these issues, consider the following:
Replace the sensitizer.
Increase the working pressure of the window film.
Thoroughly clean the profile surface before applying the film.
By addressing these factors, you can improve the adhesion of PE protective films and prevent future problems.
Protective film in the use of a period after the central performance is excellent, but the two sides of the wing up, the primary factor, in this case, is the protective film in the whole process of adhesion with the maintenance of the profile, the level of its Lashin is relatively large, in the post after a good, meet the high temperature of the natural environment, the occurrence of excess contraction, this problem occurs in the southern region of the user’s products.
Adhesive residue on profile products is a common issue with protective films. This residue is unsightly and difficult to remove, requiring time-consuming manual scraping.
Several factors can contribute to adhesive residue:
- Inadequate adhesive working pressure: If the adhesive is too dense or the working pressure is insufficient, the film may peel off, leaving residue.
- External support force exceeding thermal stress: Excessive force during handling or processing can cause the adhesive to detach and leave residue.
To prevent adhesive residue, ensure the protective film products have the appropriate adhesive working pressure and are handled carefully to avoid excessive stress.
Tianrun profile protective film adopts an effective three-layer structure; its surface layer is frosted; the use of fingerprints can effectively prevent intrusion; general finger sliding does not leave traces, even if the residue of sweat and other liquid residues, just gently wipe the hand can be cleared, a greater extent to ensure that the visual effect of the screen, the material is treated with a unique process that can effectively prevent light reflection, reduce the problem of reflections in the sunlight and the screen.
PE protective film material has a higher transmittance. It is the material of the LCD screen protection film without visual obstacles. It has good mechanical properties and impact strength, better than other materials 3 to 5 times. It is also resistant to oil, dilute acid, dilute alkali, and other solvents.
Tianrun profile PE protective film is weather resistant, can withstand a low temperature of -70 ℃, and can be raised up to 150 ℃ to prevent water vapor infiltration; it has a good water vapor barrier function, strong protective performance, environmentally friendly materials, non-toxic and non-polluting, and is a real safety material.
