So not only do we have a non-stick surface by nature, but often adhesive bonds are also required to resist extreme temperatures and / or chemical exposure. Corrosion is a gradual chemical or electromechemical attack on a metal by its surrounding medium. Chemical bonding results in a more stable situation for each atom in the bond. one chemical bond. Bond and isolate dissimilar materials – certain mechanical fasteners don’t work well with non-metal substrates, and two different metals can create corrosion problems ; Bond and seal simultaneously – adhesives don’t just bond, they can also keep fluids out or in; Reduce vibration – resilient adhesives can help dissipate energy rather than transmit it . The variations in color stem primarily from differences in chemical composition.
