Classification of Surface Treatment

Figure 3. Possible steps involved in surface treatment


Surface treatment may involve one or all of the following (refer to Figure 3 above):

Surface Preparation – the removal of oil, grease and other surface contaminants, i.e. cleaning.

Surface Pretreatment– the use of mechanical, chemical or physical methods to remove strongly absorbed surface layers and activate the surface.

Surface Post-treatment – the application of adhesion promoters or primers to improve adhesion to the adhesive and/or protect the surface.
