Zinc Phosphating Conversion Coating

TT-C-490 Type I, MIL-DTL-16232 Type Z

Paramount Metal Finishing is a Zinc Phosphating specialist to TT-C-490 Type I and MIL-DTL-16232 Type Z (Classes 1-3). Zinc phosphating is a chemical conversion coating process applied to steel and other metals. It offers several benefits, particularly in Military and industrial applications.

Benefits of Zinc Phosphating:

1. Corrosion Resistance

• Primary benefit: It enhances the corrosion resistance of metals, especially steel.
• Works as a protective barrier and helps retain paints and oils that further prevent rust.
• Often used as a pretreatment before painting or CARC coatings.

2. Improved Paint Adhesion

• Zinc phosphate coatings create a microscopic, porous surface that allows paint and other coatings to bond more effectively.
• Prevents paint peeling and flaking, especially in harsh environments.

3. Wear and Friction Reduction

• It reduces metal-to-metal contact, improving lubrication retention.
• Useful in parts where sliding or movement occurs (e.g., mechanical assemblies).

4. Base for Further Coatings

• Acts as a solid base layer for additional coatings like CARC paint and powder coating
• Oil or wax-based rust preventatives
• Offers a uniform coating thickness

5. Produces a consistent and even coating, important for:

• Maintaining tolerances
• Aesthetic finish
• Functional reliability
• Cost-Effective and Scalable
• Suitable for mass production and widely used in military, automotive, appliance, and heavy equipment industries.

Zinc phosphating offers is cost effective compared to other high-performance coating methods. It offers an enhanced aesthetic finish with a matte gray appearance that can serve as a final finish in some applications.

Heat Resistance
Zinc phosphate coatings can withstand moderate temperatures, making them useful in components exposed to heat cycles.

Applications:

• Military and industrial equipment (TT-C-490 Type I, MIL-DTL-16232 Type Z)
• Fasteners and hardware
• Automotive parts (chassis, body panels)
• Tools and mechanical components

PARAMOUNT METAL FINISHING also offers Stress Relief and Hydrogen Embrittlement Relief (HER) when required.
