Our Powder Coating Pretreatment Process

Step One: Alkaline Cleaner

The first step in powder coating surface preparation is an alkaline wash to remove contaminants like liquids, dust and soil.

Steps Two and Three: Alkaline Rinses

Products go through two rinses to remove cleaning agents from step one and ensure the removal of remaining surface debris.

Step Four: Ion Phosphate Treatment

We apply an ion phosphate solution that pickles the surface and forms a coating to improve the bond and resist corrosion.

Steps Five and Six: Ion Phosphate Rinses

In steps five and six, items go through additional rinses designed to remove all traces of ion phosphate solution from step four.

Step Seven: Reverse Osmosis Rinse

The reverse osmosis rinse washes the product in pure water to eliminate leftover chemicals and contaminants from earlier.

Step Eight: Chrome-Free Sealer

As a final step in the powder coating pretreatment process, we apply a dry-in-place, chrome-free zirconium seal and use advanced silane technology to strengthen the bond.

Once your products reach the end of our eight-stage powder coating pretreatment process, we’ll put them through immediate drying to prevent the onset of corrosion. Depending on your specifications, your items will then move to the next step in your customized powder coating process.
