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.
