First, when purchasing polypropylene anti-corrosion tape, observe its appearance to ensure that the surface is free of impurities or defects.
Second, check the adhesion of the viscoelastic anti-corrosion tape. A test can be performed on a portion of the tape. If the adhesion is weak, then re-selection is necessary.
Third, observe the holding power of the tape. High-quality anti-corrosion tapes have a longer holding power. Poor quality tapes will fall off shortly after wrapping; this should be noted when purchasing.
