Properly taping a motor connection

Pure acrylics have a lower tack (“stickyness when dry” for the layman) and less adhesion on hard-to-bond plastics such as high- and low-density polyethylene (HDPE & LDPE) and polypropylene (PP) than modified acrylic or rubber adhesives. Pure acrylic adhesives are mainly used on tapes whose applications are bonding, sealing or surface protection.
If you've ever spilled a glass of water on a roll of Scotch tape, you know that many tapes lose their stickiness when they get wet. Water-activated tape, however, is unique because its adhesive is only activated by water. When the adhesive on water-activated tape is moistened, it bonds to whatever surface it is applied to. If you apply water-activated tape to a box and the box later winds up stuck in the rain, you can rest assured that the adhesive will remain intact.
