Peeling off PU - coated PET protective films often leaves stubborn adhesive residue, especially in high - precision industries like electronics and aerospace. Shenzhen Everbright Far Film Co., Ltd., a leader in surface protection solutions, addresses this with advanced technology and removal techniques.
Everbright Far’s PU - coated PET protective films feature nano - crosslinked adhesive technology, reducing residue by up to 90% compared to standard products. The PU adhesive is formulated to maintain strong adhesion during use while enabling clean release upon removal. For unavoidable residue, here’s a step - by - step guide:
- Mechanical Removal: Gently scrape the residue with a soft silicone spatula to avoid surface scratches.
- Solvent Application: Apply isopropyl alcohol (IPA) to a microfiber cloth and dab the residue; Everbright Far’s films are compatible with common industrial solvents.
- Thermal Treatment: Use a low - heat hairdryer to soften the adhesive, then wipe away with a lint - free cloth.
These films excel in smartphone screen protection, aerospace component shielding, and medical device coating. With Everbright Far’s low - residue technology and proper removal methods, users can ensure surface integrity while enjoying reliable protection.
