Abstract

A method to electrostatically powder coat non-conductive substrates has been developed. This method uses a thin coating of an aerosol antistat containing a fatty quaternary ammonium compound onto the substrate prior to powder painting. Microstructural analysis of the epoxy coatings has shown that gases are trapped within the coating causing voids. The formation of large voids with diameters as large as 50 μm appear to be due to water-vapor released from the non-conductive substrate during curing of the epoxy coating. Even with the voids within the epoxy layer, the coating on the antistat treated substrate passed military specifications for adhesion and solvent resistance.
