Corrosion inhibitors under powder coating
The image on the left shows how important it is to remove dust after grit blasting. Water is photographed forming balls after repelling from dust, which represents paint on dirty or dusty metal.
Technically advanced corrosion inhibitor used for Tri-Resin™ System
Chromate rust inhibitor suspended in a combination of resins including Acrylic is used to protect the metal under the primer.
Quality Powder Coaters
If you use a competitor, ask if they wash the grit and dust from the steel before applying the powder coat primer.
If the paint is applied on dust, the adhesion will be poor and rust can creep under the coating.
