FIPROPHOS 520

PRODUCTS FOR SURFACE CONVERSION AND PRE-PAINTING

Technical features

FIPROPHOS 520 is a liquid phosphodegreaser designed for the pre-painting treatment of iron, aluminum and zinc products for immersion or pressure lance applications.
FIPROPHOS 520 is used in industrial painting and performs a combined action of degreasing and phosphating. The treated surfaces, in fact, as well as being clean, are covered with a thin amorphous layer of ferrous phosphate, blue / red, which increases the corrosion resistance characteristics of the metal and which constitutes an excellent anchorage for subsequent painting.

Usage and Applications

FIPROPHOS 520 is used by immersion at concentrations between 4% and 6% at temperatures between 40 ° C and 60 ° C with contact times of no less than 2 - 3 minutes.
For use with a pressure lance, however, use the product at a concentration of 0.5% - 1% with temperatures above 50 ° C.
In both cases, rinse and dry the pieces thoroughly before painting.
To obtain good phosphating, the pH of the baths must be kept in a range between 3.5 and 5.0.
