Manganese Phosphate Coatings
Manganese Phosphate coatings are most commonly chosen for their break-in or wear resistant properties. The manganese phosphate coating not only prevents metal-to-metal contact between moving parts, it also has excellent oil retentive properties for both lubricity and corrosion protection.

Description |
| Phos Dip® M-22 | Heatbath®’s premier manganese phosphate coating, used to reduce wear and prevent galling of moving parts. Meets or exceeds the requirements of MIL-DTL-16232 for Type M coatings. An immersion process typically used with a grain refining pre-dip. Operating temperature 200ºF. Achieves coating weights of 1500+ mg/ft2. |
| Phos Dip® M-28 | A non-nickel version of Phos Dip M-22 for use in applications where nickel in effluent is prohibited. |
| Phos Dip® M-33 | A stable manganese phosphate coating bath that operates iron-free and at 180ºF. Produces a smooth, uniform microfinish with minimal attack on the base metal. Reduces friction in bearing applications. Coating weight is 700+ mg/ft2. A grain refining pre-dip is preferred. |
| Ultraphos 1000 | Like Phos Dip M-22 manganese phosphate coating bath, used in applications where wear is a constant factor for consideration. The resultant manganese phosphate coating readily absorbs lubricating oils for fast break-in. Prevents scuffing, galling and seizing of metal components. Provides corrosion resistance when used with rust preventative oil. Meets MIL-DTL-16232 and produces coating weights in excess of 1500 mg/ft2. |
Manganese Phosphate Grain Refining Pre-Dips |
|
| Phosphate Conditioner MGR | Used just prior to the manganese phosphate coating bath, the conditioner activates the ferrous metal surface and promotes the deposition of a smooth, uniform coating. Using a conditioning step often eliminates the detrimental effects of strong alkaline or acid pre-cleaning. Highly recommended for job shop applications. No heat needed. Air agitation is recommended. |
| Phosphate Conditioner MGR II | Like the Phosphate Conditioner MGR, but produces an even finer grained, ultra smooth, manganese phosphate coating. Used at just 0.5 oz./gallon. |
