SC-485 Metal-Guard Iron Phosphating Liquid

SC-485 produces a uniform, fine-grained phosphate coating on mild steel, carbon steel, aluminum and zinc coated-steel. This coating creates an excellent base for paints by increasing the adhesion of all organic finishes and retards rusting of painted surfaces when scratched or injured. An easy-to-control liquid, SC-485 simplies phosphating operations, saves processing time, reduces equipment requirements; inject or meter Metal-Guard into washing equipment straight from drum.

SC-485 has exceptional detergent action for removing dirt accumulations and fabricating oils; it performs readily in hard or soft water with no scaling of tanks or heating coils; a labor and energy saving feature.
