Is water used as a weak adhesive in any manufacturing applications?

Asked by Ltryptophan (12091points) February 28th, 2017

Water seems to have a tacky ability. This is very light, but maybe that is just what the doctor ordered.

Have you ever heard of this use?

Maybe with certain paper products, or picking up and dropping off light objects.

Water possesses what is known as a covalent bond that is IMO relatively weak when referring to straight water as an adhesive. Water IMO in an adhesive works best as a solvent/wetting agent in water soluble polymers/fillers/additives to help them achieve higher bonds strengths to a variety of substrates.

People use it as an adhesive to turn a page.

The attraction of water molecules to each is what causes surface tension. Surface tension has a lot of applications, though not much as an adhesive. I did a Web search on surface tension and found this I wish they had gone into more detail
