A low foaming water-based iron phosphate pretreatment that produces a uniform conversion coating on steel or aluminum surfaces. It is formulated to remove moderate soils such as metalworking fluids, stamping oils, drawing compounds, rust preventatives, etc. The coating becomes an integral part of the metal surface, producing a characteristic color ranging from iridescent blue to a golden hue (aluminum coatings appear slightly golden).
