4 or 5 stage phosphate
Steelcote 1400 is a zirconium based product that provides outstanding paint adhesion and corrosion resistance to steel and aluminum. For steel having 2-3 mils of paint, it consistently achieves over 1200 hours in NSS with less than 3 mm creep from the scribe and no sealer is required. Steelcote 1400 contains no phosphates or heavy metals. It is operated using similar times, temperatures, and pH's as traditional iron phosphate systems and does not require DI / RO for bath make-up or water rinses. It imparts a blue to purple color to steel.
Shock Absorbers pretreated with Circle-Prosco chemisty
A top performing iron phosphate that imparts a blue or gray coating. It is operated at only 1 to 2% concentration and is an ideal product for high volume applications. It can also be used with our PCA-89 in a 3 stage application.
Steelcote 1700 is a zirconium based cleaner-coater that provides cleaning as well as corrosion resistance and paint adhesion in a spray wand application.
A cleaner/phosphating compound that cleans and phosphates iron, steel and galvanized steel.
