Rust solvent
The anticorrosive phosphating composition of PFK is intended for use as phosphating concentrate and rust solvent at surface preparation steel (pig-iron, galvanized) designs and products before putting paints and varnishes in industrial and postroyechny conditions, and also means for chemical removal of rolling scale. When processing prokorrodirovavshy metallic surfaces the PFK rust solvent turns rust layer to 100 microns into phosphates and creates protective anticorrosive phosphatic film on steel surface.
The PFK rust solvent represents complex structure on the basis of orthophosphoric kislotya of zinc oxide with the modifying additives.
The PFK rust solvent is fire and explosion-proof.
Consumption rate of the PFK rust solvent from 110 to 300 g/m2 depending on thickness of rust and way of drawing.
