Iron Phosphate Pre-Treatment

Iron phosphate is a critical pre-treatment process that enhances the durability, adhesion, and corrosion resistance of powder-coated finishes. At Premium Powder Coating, we utilize both a batch side spray wand system and a three-stage automated line system to ensure superior surface preparation for all metal parts.

Our Iron Phosphate Pre-Treatment Process:

Batch Side Process (Ideal for Custom Work):

1. High-Pressure Wand Treatment – Iron phosphate is applied using a high-pressure spray wand to clean and prepare the metal surface.

2. Fresh Water Rinse – Removes any residual chemicals and contaminants.

3. Blow Down – Ensures all excess water is removed to prevent spotting or uneven coating.

4. Pre-Bake – Parts are heated to remove any remaining moisture and ensure optimal adhesion.

Three-Stage Automated Line (For High-Volume Production Runs):

1. Iron Phosphate Wash (Stage 1) – A controlled, automated wash applies iron phosphate for consistent treatment.

2. Fresh Water Rinse (Stage 2) – Removes excess phosphate and debris.

3. Fresh Water Rinse (Stage 3) – Ensures a completely clean surface before coating.

4. Immediate Pre-Bake – Parts are moved directly to a dedicated pre-bake oven for moisture removal and optimal adhesion.

Why Iron Phosphate Pre-Treatment?

• Improved Adhesion – Creates a strong bond between the metal and powder coating.

• Corrosion Resistance – Adds a protective layer to prevent rust and oxidation.

• Enhanced Durability – Extends the lifespan of the coated surface.

• Precision & Efficiency – Our dual-system approach ensures the right treatment for any job size.

By integrating both batch and automated processing, we guarantee high-quality, long-lasting powder-coated finishes for industrial, automotive, and architectural applications.
