Pretreatment/Wash System for Powder Coatings vs. Liquid Paints

When powder coatings efficiently cover a treated part, they provide superior performance over that of liquid paints; however, it is imperative to ensure the wash process for parts is completed thoroughly. Solvent-borne paints are more tolerant of soils left on the piece due to insufficient cleaning.

Powder does not have solvents, so it is necessary to make sure that the washer cleans the parts well. The high cleaning standard for powder-coated parts has the added bonus of generally being a good practice to maintain.

Iron phosphate is the most common powder coating pretreatment used. For a higher level of performance, zinc phosphate works impressively well with powder.
