Sticky Truth about 3M Tape and Other Adhesive Tapes: Strength of Bond

Not all substances are composed of molecules that exhibit wetting or induce Van der Waal’s forces. Polymer, the main component of most adhesives are among the materials which show strength in both processes, making them effective for pressure sensitive bonding. Likewise, they have large molecules such that even with minimal Van der Waal’s forces, they are strong enough to produce a binding reaction with the molecules of other substances.
