Pretreatment / Cleaning

Pretreatment is the process of removing both organic and inorganic soils to prepare parts for finishing. At Westside Finishing this is done using an iron phosphate solution that we apply in one of three ways depending on the size of the part. The iron phosphate solution not only cleans and etches the part, it also provides a better surface for coating adhesion and adds enhanced corrosion protection. The three methods of pretreatment in our Western Mass facility include our three stage conveyorized washer, our batch cabinet washer and a manual wand system.
