CORROSION PROTECTIVE COATING, ZINC NICKEL ALLOY, TRIVALENT PASSIVATE, SILVER ***TO BE USED WITH FORD WSS-M99P1111-A***
|Publication Date:||22 March 2016|
The materials defined by these specifications are corrosion protective coatings applied sequentially per supplier specifications over steel. They consist of an alkaline zinc nickel alloy electrodeposit and a trivalent chromium passivate/adhesion promoter. A3 is followed respectively by an organic seal, a cathodic electrocoat, or a waterborne top coat. When used with an integrally cured torque modified post dip, these processes provide consistent torque-tension control.
All processes are free of hexavalent chromium, lead and cadmium.
