low zinc technology

low zinc technology
A technology used in present-day phosphating processes. Normal zinc phosphating baths used as pre-treatment for painting contain approximately 2-4 grams-per-liter (g/l) zinc and approx. 5-10 grams-per-liter (g/l) phosphorus pentoxide. In low-zinc baths, the corresponding values amount to approx. 0.4-1.7 g/l zinc and 12-16 g/l phosphorus pentoxide
