Tending to adhere.
Any substance used for adhering or sticking; glue.
Substance that sticks two surfaces together. Natural adhesives (glues) include gelatin in its crude industrial form (made from bones, hide fragments, and fish offal) and vegetable gums. Synthetic adhesives include thermoplastic and thermosetting resins, which are often stronger than the substances they join; mixtures of epoxy resin and hardener that set by chemical reaction; and elastomeric (stretching) adhesives for flexible joints. Superglues are fast-setting adhesives used in very small quantities.
The marine bacterium Shewanell colwellii secretes a natural glue, PAVE (polysaccharide adhesive viscous exopolymer), in large quantities. As PAVE can be used in wet conditions and is resistant to sea water it was being developed commercially 1994 as a sealant for ships’ hulls.
