Customer needed 2000+ hours of salt spray resistance on this coil as it was to be used in a marine engine compartment.  Traditional Powder coating applications could not penetrate the tight spaces between the metal coils and the plastic relay casing.  A fluid bed application of Epoxy powder was used to bridge the gaps and create a totally encapsulating coating capable of delivering up to 3x the customer requirements for salt spray resistance.

This customer needed to coat these small stepper motors for use in chemically harsh environments.  Unfortunately, the motors cannot be subject to the intense heat typically needed for standard Fluid Bed Powder coating.  PDC worked with its suppliers to find a suitable coating that could be applied at temperatures below 300 degrees F while meeting the strict chemical resistance required for the application.
