For an adhesive to bond adequately it must penetrate the surface to be bonded (sometimes referred to as wetting) and change from a liquid into a solid; a chemical reaction known as ‘Polymerisation’.
The penetrating /wetting stage of the bonding process is vital to achieve a satisfactory bond. If the adhesive has not successfully penetrated the surface the bond will not hold.
Correct surface preparation plays an important role in this stage of the bonding process.
When the adhesive has penetrated the surface it transforms into small solid blocks, which lock into the surface creating a bond. In some ways this is similar to the hook and loop principle used on Velcro type fasteners.
