Parker Chomerics CHO-SHIELD® 608 EMI coating is a one-component, silver-filler conductive polyester coating that provides superb EMI shielding and a very thin dry film thickness. CHO-SHIELD® 608 is a silver-colored polyester that is able to provide coverage at a very thin coating thickness (0.0005″”) and difficult part geometries. Typical applications include electronic enclosures and assemblies. Features and Benefits:• One component solution so no measuring and mixing of components is required• Designed for high volume spray applications• Exceptional working life (required elevated temperature heating)• High EMI shielding properties (>85 dB) due to pure silver flake filler• Flexible coating which provides great adhesion to a variety of substrates• Excellent wettability for uniform coating application • No primer required
