Vacuum metalized finishing often includes the application of a specially formulated paint as a basecoat to promote adhesion and to provide a smooth surface, assuring maximum brightness and luster.

This step is only needed for reflective finishes and chrome and metallic coatings and is not necessary for EMI/RFI shielding.

Mueller Corporation has developed proprietary coatings for many substrates, including flexible plastics, which are suited for both high and low temperature applications. Tooling fixtures are placed into the paint cell for basecoat.

All coatings are applied by High Volume Low Pressure spray guns (HVLP) by three different methods including; six axis robotic paint cells, automatic reciprocating paint cells, or by hand for low volume and prototypes. Our robotic spray cells include 8 bank color change which allow us to apply a variety of coatings needed for a job shop environment including conductive paint for EMI/RFI shielding, metallic paints, and basecoats and topcoats for vacuum metalizing. After paint application the tooling fixtures are placed into batch convection ovens to cure the paint.
