Zinc Phosphating - Zinc Phosphate Coating - Zinc Phosphatizing

Activation is mandatory for zinc phosphating and in its absence, because of the relatively high pH values involved, a thick and coarse-crystalline coating is formed which is quite unsuited of subsequent painting. Conditions for the rinse, post-rinse and drying stages differ little from spray phosphating. SPRAY PROCESS.
