Parker Chomerics CHO-SHIELD® 2056 EMI coating is a one-component, Ag and Ag/Cu filled acrylic paint designed for high levels of EMI shielding on plastic substrates. CHO-SHIELD® 2056 is a copper-colored coating that provides excellent reliability and EMI shielding (>75 dB) on a multitude of plastics. Due to minimal application requirements and superior electrical properties, CHO-SHIELD® 2056 is the most cost effective EMI shielding solution for electronic enclosures. Features and Benefits:• Thin coating allows for time and money savings for processing• Silver flake provided anti-microbial characteristics for medial device applications• One component coating means no measuring and mixing is required • Can be applied using standard spray painting equipment, not requiring capital intensive equipment• Meets UL Specification 746-C for adhesion• Anti-static protection and excellent surface grounding properties• Room temperature drying means no high temperature curing is necessary (but elevated temp curing is available for faster cure time)• Excellent leveling and smooth surface coverage• Thin dry film thickness limits wastage due to overspray and the frequency of mask washing • No primer required
