Will PU Invisible Car Film Leave Adhesive Residue?

[LeMarley]

PU invisible car film may leave adhesive residue. Here is more relevant information: 1. Reasons for adhesive residue: (1) During installation, if the paint surface is not thoroughly cleaned (or improper cleaning agents are used), residues on the paint surface may react chemically with the adhesive, causing peeling. (2) The adhesive layer of the invisible car film lacks sufficient heat resistance. Under high temperatures and sunlight, chemical reactions occur, altering the material and leading to peeling. Therefore, apart from incorrect installation, the issue of adhesive residue after removing the invisible car film is primarily due to problems with the product's adhesive layer. 2. Materials of invisible car film: (1) PVC material is relatively hard, prone to yellowing, mostly domestically produced, with very sticky chemical adhesives. (2) TPH material is very soft and easily torn, offering slight scratch repair capability but also very prone to yellowing. (3) TPU material significantly improves toughness, has good yellowing resistance, and offers strong scratch repair capability.
