Method for powder coating a non-conductive plastic substrate wherein an adhesive/primer is used in the process to increase the surface conductivity of the substrate

摘要

A method of powder coating thermo powder resins to non-conductive plastic substrates, in particular, to polyamide materials and other non-conductive plastic substrates. After cleaning the substrate, a water-based adhesive/primer is applied to the substrate and then cured to promote adhesion, protect the substrate from unwanted chemical reactions and increase the electrical surface conductivity of the substrate to provide to better coating and transfer efficiency of the thermosetting powder to the substrate.
