Conversion Coatings: Iron Phosphates

Pre-paint conversion coatings for Aluminum, Iron & Steel.

NuKoat products are designed to clean and iron phosphate in one easy step. NuKoat provides a superior foundation for painting providing excellent corrosion resistance. NuGeneration Technologies’ NuKoat line of Iron Phosphates is highly effective, cost efficient, and easy to use.  NuGeneration Technologies offers 5 stage iron phosphates for the most demanding jobs to simple to use one step/no rinse iron phosphates.  Best results are achieved with 3 to 5 stage processes:  See Charts Below.

NOTES: 
(1) Molybdate-based Iron Phosphate conversion coating for aluminum and aluminum alloys as an environmentally benign replacement of chromate-based conversion coatings. The molybdate based iron phosphate conversion coating can be applied by dipping, painting, or spraying, with short treatment times at low temperatures, and is compatible with existing cleaning and pretreatment procedures.

    Some Municipalities are now requiring products that are molybdate free...NuKoat 55 and 55T (also 53MF and 33 MF)  are iron phosphate conversion coatings that meet OSHA and EPA regulations for environmentally friendliness and worker safety.
 
(2) Want to determine your own coating weights (iron or zinc phosphate).  FEDERAL SPECIFICATION:  TT-C-490E: CHEMICAL CONVERSION COATINGS AND PRETREATMENTS FOR FERROUS SURFACES (BASE FOR ORGANIC COATINGS)
