Phosphate Conversion Coating
Phosphate conversion coating is used as a protective base for iron and steel substrates. This coating provides a uniform base to apply organic coatings.
K&L Plating provides zinc phosphate conversion coating to steel and iron surfaces in several applications. Our coating is corrosion-resistant, and prevents galling, scuffing, and seizing of moving parts. It can serve as a uniform, non-reflective finish, or be used as primer for highly decorative painted finishes.

Why Choose Phosphate?
Phosphate coatings provide superior uniform bonding capabilities for organic coatings like paints, lacquers, or a CARC military topcoat. When applied to steel or iron, it provides a non-reflective finish which can be dyed to your specification. It also provides corrosion protection to the metal.
Common Applications
- Defense: CARC primer, applications that desire non-reflective finish
- Aerospace: moving parts & threads, primer for special coatings
- Automotive: base for coatings, engine, transmission
- Heavy equipment: gears and bearings
- Oil and Gas: primer for components
