Case Study Zirconium Conversion Coatings
Temperature: Amb. – 100 F
Concentration: 2.0 – 3.0 %
Dwell Time: 60 sec
Multi-metal immersion pretreatment process
Detergent iron phosphate
Steel, galvanized, aluminum
Parts must be able to achieve a class A finish as necessary, and meet customer’s applicable adhesion, salt spray, impact, and mil spec TT490 requirements.
This line was successfully converted from iron phosphate to ZirKote 602, a zirconium based conversion coating technology. The product has excelled in achieving the customers expectations. This customer improved line performance, eliminated phosphates from their conversion coating bath, reduced the operating temperature from 140F to ambient, and minimized maintenance costs associated with dumping and disposal of spent bath.
