Each of the various approved cover materials has a particular place in the SFICO Process®. Selection of materials as anode wraps is primarily based upon their compatibility with each preparatory and/or plating solution and their purity. Wear resistance, absorbency, and abrasiveness are the secondary factors in material selection. Using the wrong cover material or impure material can have serious detrimental effects on adhesion and deposit quality. It is imperative to use only approved cover materials.
