What Causes the Adhesive on the Rear Window Film to Peel Off?
1 Answers
The reason for adhesive peeling off the rear window film may be due to human factors and inherent adhesive factors causing the protective film adhesive to detach. Human factors: During the operation, high-temperature resistant protective film is required in high-temperature conditions; Before applying the film, ensure the surface is free of grease, banana oil, and other chemical residues, otherwise, these residues can easily react chemically with the adhesive, leading to adhesive peeling. Inherent adhesive factors: Based on the residual condition of the pressure-sensitive adhesive on the protected surface and the substrate, the phenomenon of residual adhesive on the protective film can be divided into the following three situations: Cohesive failure, where both the protected surface and the substrate have pressure-sensitive adhesive, and the adhesive-coated surface of the protective film loses its gloss; Adhesive failure, where the protected surface has a significant residue of adhesive skin, and the substrate is visible on the adhesive-coated surface of the PE protective film; Migration residue, where the protected surface has a small amount of pressure-sensitive adhesive residue, and the adhesive-coated surface of the PE protective film maintains good gloss.
