Is a Primer Base Coat Necessary?
Unlike liquid coatings, powder coatings are more corrosion resistant to the elements. Pretreatment is vital to any coating process. Our coatings go through many different process’s that include degreasing, di rinsing, iron phosphate (etches the metals) and sealers. Also we offer media blasting to remove scale and rust before coatings. Powder coating primers such as our zinc rich primer offer the best corrosion resistance to the products. By adding a powder coating primer, you are adding additional coating life to the part. Areas with exposure to the elements such as sprinklers and pools (chemicals that are in pools can cause corrosion) and high traffic areas can benefit from zinc rich primers by adding more film build thickness and salt spray resistance to the parts.
