LOW-TEMPERATURE AMORPHOUS PHOSPHATING
A solution of low-temperature amorphous phosphating has been developed, which makes it possible to obtain coatings at room temperature that meet the requirements of GOST 9.402-2004. This composition makes it possible to obtain amorphous phosphate films on a steel substrate weighing up to 0.2 g / m2 at a temperature of 20-25 ° C with a processing time of 5 minutes.
