[b]LOW TEMPERATURE / PHOSPHATE-FREE CONVERSION COATINGS[/b]
A cost effective high performance environmentally friendly alternative to iron phosphate

Energy costs are a major concern for metal finishing operations as well as issues of environmental compliance. Waste water treatment facilities in certain areas of the country are tightening phosphate and heavy metal discharge limits on metal finishers. To address these concerns, a line of inorganic conversion coating products has been developed. They focus on temperature reduction and phosphate discharge elimination while improving corrosion resistance.

Formulated to replace traditional iron phosphate, these products require no or very little heat to deposit an inorganic conversion coating. Conventional iron phosphate products, on the other hand, can require temperatures of 130-160 F. Another benefit of this new technology is usage; a maximum of about 2% by v …
