Incotec Coatings... Advanced coatings for an advancing world.

Conversion Coatings

Incotec Phosphate Conversion Coatings

Incotec Phosphate coating is the process of chemically converting the surface of a material referred to as the substrate (typically a metallic element) into a layer of a non-metallic, crystalline conversion coating. Incotec Phosphate coatings serve as a surface preparation for further coating and/or painting, a function it performs effectively with excellent adhesion and electric isolation. The porosity allows the additional materials to seep into the phosphate coating and become mechanically interlocked after drying. Incotec Phosphate coatings adhere to the strict requirements of NADCAP AC7108, ensuring a consistent quality product.

INCOTEC Manganese Phosphate Coating

Incotec Manganese Phosphate coatings are used on steel parts for corrosion resistance, lubricity, or as a foundation for subsequent coatings or painting. Incotec Manganese Phosphate coatings do not provide corrosion resistance on their own because the coating is porous. Therefore, oil or other sealers are used to achieve corrosion resistance. This coating is called a phosphate and oil (P&O) coating. Incotec Manganese coatings are used to help break in components subject to wear and help prevent galling.

INCOTEC Passivation of Stainless Steel

Incotec Passivation is the removal of exogenous iron or iron compounds from the surface of stainless steel by means of a chemical solution. Typically this is done with an acid passivation solution that will remove the surface contamination but will not significantly affect the stainless steel itself. Passivation treatments improve the surface condition of stainless steel by dissolving iron that has been imbedded in the surface during forming or machining. If allowed to remain, the iron can corrode and give the appearance of rust spots on the stainless steel. Passivation, which consists of immersing stainless steel components in a solution of nitric acid, will dissolve the imbedded iron and restore the original corrosion-resistant surface by forming a thin, transparent oxide film. Incotec has continually improved the process over the years and uses a proprietary formula of state-of-the-art methods to strictly adhere to the requirements of AMS 2700.
