Manganese Phosphate Coating

Available Across the United States

Also known as Parco Lubrite and Parkerizing, manganese phosphate coatings are formed via immersion in a dilute phosphoric acid solution and are dark gray in appearance. When completed, these coatings prevent galling and improve break-in properties. 

Keystone Corporation’s manganese phosphate coatings are used for a variety of applications, inclusing the production of bearings, bushings, fasteners and other industrial products.

Various Applications for this Coating

Due to its properties, manganese phosphate coatings excel in a wide variety of applications including:

  • Serving as a uniform base for paint adhesion
  • Good non-metallic crystalline coating, ideal for absorbing oil or wax to enhance corrosion protection.
  • Excellent for protecting parts from corrosion or wear
  • Helps metal-to-rubber adhesion
