Iron Phosphates

Iron phosphates produce an amorphous coating that, when applied to the base substrate, provides improved paint adhesion and contributes to the overall improvement in quality of the painted part. Some iron phosphates also exhibit synergistic properties with traditional corrosion inhibitors to provide economical storage protection from corrosion.

Phosphate Coatings: Iron

Hubfos 12 S Low temperature applications. Amorphous iridescent iron phosphate on ferrous metals. Spray: 3-6% by volume, 100-140°F. Coating weight: 25-50 mg/ft2. Specifications TT-C-479-C, Type II. Low temperature application in spray operations. Cleans and phosphates in one operation. May be used on cast iron, steel, zinc and aluminum alloys as a pre-paint or organic coating base.
Hubfos 150 Amorphous, iridescent, iron phosphate on ferrous metals. Spray or Immersion: 2-6% by volume, 90-160°F. Coating weight: 60-100mg/ft2. Hubfos 150 is classified as a cleaner phosphate. This unique phosphate has the ability to used with the proper Metal Guard® to provide excellent corrosion protection, that can provide superior shelf life protection.
