Electrostatic Powder Coating: How it Works and Why it Matters for Light Poles and Bases
Electrostatic powder coating is a process that uses an electric charge to apply a dry powder coating to a metal surface. The powder is comprised of polymer resins, curatives, pigments, and leveling materials that are melted together and then ground to a fine texture. The metal component being coated is grounded, and then the negatively charged powder is applied. The negatively charged powder particles are attracted to the grounded metal part, causing the powder to stick to the metal…..
