While there are adhesives that provide acceptable levels of performance, there is on ongoing need for more options to meet this key requirement.
Web11 jan. 2024 · There are times when installers have to put an overlay piece (e.g., strip or cut vinyl) on top of a vinyl wrap film that has low surface energy, like a matte metallic film. In this case, the overlay piece might not stick well if you do not prep it properly. Here are a few tips for you to handle the situation and achi WebLow-energy surfaces such as synthetics are a special challenge, for example. If you choose a less suitable adhesive tape, it will peel off more easily. Difficult surfaces with poor adhesive properties are considered to be polyethylene (PE), polystyrene (PS), polytetrafluorethylene (PTFE), polypropylene (PP), silicone or powder coatings.
