Effective powder coating pretreatment is the foundation of a durable finish. BLUETEE recommends a structured process:
Clean & Degrease to remove oils and soils (alkaline cleaners or solvents).
Rinse with DI or fresh water to prevent residue carryover.
Mechanical prep (as needed) such as blasting to create uniform profile and remove rust/scale.
Conversion Coating—iron/zinc phosphate or zirconium/ceramic systems—to promote adhesion and corrosion resistance.
Final Rinse & Seal (optional) and dry thoroughly to avoid outgassing and defects.
With proper pretreatment and controlled film build and cure, BLUETEE powders deliver smooth appearance, strong adhesion, and long service life on steel, aluminum, and galvanized substrates.
