Low energy surfaces such as plastic are hard to stick to – ink drops will run off the surface. The same applies to adhesive. Low-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.
By contrast, there are materials with high-energy surfaces. Adhesive sticks to them very well. The adhesive spreads widely and evenly on the surface. High-energy surfaces include steel, aluminium, polyvinyl chloride (PVC) and polycarbonate (PC). Adhesive sticks to them very easily and reliably.
But there are also solutions for anyone who would like to attach adhesive to surfaces with low surface tension. The result of the measurement is not critical for the resulting adhesive bond. Surface tension can be changed very easily with primer. It increases the surface energy chemically and ensures that the adhesive will be able to stick well. Incidentally, thorough cleaning and degreasing of a surface often produces miracles. The surface energy also changes here.
