Dielectric coating for stainless steel  

++

We need a good electric insulating (dielectric) coating on a stainless steel sheet metal part (304 alloy). The insulation is needed for ESD compliance; I don't have hard numbers on the breakdown voltage needed, but any dielectric strength will help. This surface should preferably be flat black, though other options could be considered. Low cost is, of course, very important.

Is a polyester powder coat a good choice? I figure it should be, since polyester sheet has a high dielectric value. Anything else I would do well to look into?

Thanks,

Will the coating be subject to wear of any kind? What kind of atmosphere, application is the part for?

+++++

The polyester resins used in the system of powder coating have a good dielectric strength specially after the curing with TGIC (TRIGLYCIDYL ISOCYANURATE)10MIN/200C.
Most polymer have a good dielectric strength , direct current voltage at which the dielectric break down occurs, (100-300kv/cm).
