Ternary phosphating

Function positioning:

Pretreatment between coating processes (degreasing, surface adjustment, phosphating, passivation)

Application scenario:

Coating metal pretreatment line

Application substrate:

Cold-rolled sheet, hot-rolled sheet, steel sheet, hot-dip galvanized sheet, electro-galvanized sheet, alloy sheet, aluminum and alloy sheet

Value advantage:

It can process a variety of composite substrates at the same time (there is no requirement for the upper limit of the proportion of aluminum parts) to form a standard phosphate conversion layer, which can improve the bonding force (adhesion), corrosion resistance, decoration, etc. between the substrate and the post-treatment electrophoretic paint; The product and the process are mature, stable and have good matching, wide operation window, good construction performance and high quality level. Degreasing can provide phosphorus-free and nitrogen-free series, surface activity can provide emulsification and non-emulsification and high, medium and low temperature series, surface container can provide zinc and titanium series, phosphating can provide high, medium and low temperature series, passivation can provide chromium-free passivation and organic passivation series.
