PARAMETER

First, an overview


The YH-3500 film agent is further improved based on the traditional zinc film (phosphating) agent. It has the disadvantage of producing large amounts of sediment when it is treated by general zinc phosphating process. The YH-3500 film processing process produces little sediment and the treatment temperature is low: the minimum 5 degree C. The phosphating film is more compact and compact than other zinc systems. The thickness of the membrane is l-3um, and the YH-3500 coating agent is suitable for the general paint, powder, Yin (Yang) polarity electrophoresis and other pretreatment processes.
