Does the zinc-phosphate finishing (or pre-finishing) layer become an electrical conductor?

December 15, 2008

I am in the motor and generator business, and I have been asked to use zinc phosphate on parts that are supposed to be electrically isolated. I am worried about the insulation effects that the zinc phosphate will have on the machines.
Will this chemical etch the already existing varnish and other insulations?
Does the layer of this chemical act as an electrical conductor?

The phosphate coating won't conduct electricity. But, I don't know if I'd rely on it as an insulator.
