Our Phosphating Process
Phosphating is a chemical conversion process on a metal surface into an insoluble lattice of crystalline phosphate.
Once applied, the zinc phosphate coats uniformly, is non-conductive and resists corrosion.
Corrosion resistance you can count on
Zinc phosphating can extend the shelf life of your products in corrosive environments. By combining our zinc phosphate treatment with rust-inhibiting oils, wax, and other organic coatings, we can help your product withstand harsh conditions. Our treatment has been rated to withstand up to 168 hours of continued salt spray.
Break-in your parts without breaking your parts
By preventing metal-to-metal contact, our zinc phosphate coating permits the rapid break-in of moving parts without scuffing or welding. Plus, the oil held by the crystals improves the lubrication of the treated surface and imparts corrosion resistance. Even after the break period is complete, a smooth and fine distribution of oil remains, assuring continued lubrication.
Strengthen the bond between metal and coating
Zinc phosphate reduces the electrochemical activity of the surface of a metal and forms a strong physical and chemical bond with organic coatings. Zinc is often used as an under adhesive in paint or other organic coatings. The highly-absorbent phosphate crystals allow paint to penetrate into tiny fissures and increase the total surface area available for bonding. The phosphate also insulates the base metal, preventing corrosion creep and extending the life of the finished product.
Applications
- Can be used with rubber or metal bonding
- Creates a uniform base for paint adhesion
- Protects parts from corrosion resulting from abrasion
- Absorbs oil, wax and a variety of other topical fluids
Advantages
- Cost advantage compared to other coating methods
- Creates a uniform cosmetic black finish when applied over a pre-blackened surface
- Amazing corrosion protection—can withstand up to 168 hours of continuous salt spray (when combined with rust inhibiting oils)
- Dry to touch lubricants can be added—less mess and satisfies a greater range of handling requirements
