Conductive paint CHO-SHIELD® 2000

polyurethaneurethanefor aluminum

Parker Chomerics CHO-SHIELD® 2000 Series are a family of electrically conductive coatings providing a corrosion resistant conductive surface coating on aluminum or composite substrates. By reducing moisture penetration, CHO-SHIELD® 2000 Series coatings offer corrosion protection for enclosure flanges which mate with EMI shielding gaskets. These tough, urethane coatings offer a highly conductive interface which improves overall EMI shielding performance. When used as a coating on a composite or other non-conductive surface, it provides the conductivity necessary to achieve excellent shielding effectiveness while maintaining their electrical and mechanical stability in hostile environments. CHO-SHIELD® 2000 Series are three-part, copper-filled urethane coating systems which have been formulated with special additives and stabilizers to maintain their electrical stability even at elevated temperatures which prevent aluminum surfaces from corroding in high humidity and/or marine environments. CHO-SHIELD® 2000 Series are designed to be used with CHO-SHIELD® 1091 primer on chromate conversion coated (MIL-DTL-5541 Type I, Class 3) aluminum substrates. Features/Benefits: • Three component urethane system • Corrosion résistant copper filler • Exceptional mechanical properties -65°C to 85°C (-85°F to 185°F) including abrasion and scratch résistance • Pre-measured kits allows easy mixing of components in one container • Significantly more cost effective than silver filled epoxies • Protects aluminum and graphite composite airframes from corrosion
