Parker Chomerics CHO-SHIELD 2003 SERIES CORROSION-RESISTANT CONDUCTIVE COATINGS

Parker Chomerics CHO-SHIELD® 2003 is an electrically conductive coating designed to provide a corrosion resistant conductive surface on aluminum or composite substrates. By reducing moisture penetration, CHO-SHIELD® 2000 Series coatings offer corrosion protection for enclosure flanges which mate with particular EMI shielding gaskets.This tough, urethane coating offers 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® 2003, like all of the 2000 Series coatings, 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® 2003 contains soluble chromates to minimize the effects of galvanic corrosion of the aluminum substrate, even in the event of a coating scratch. CHO-SHIELD® 2003 is designed to be used with CHO-SHIELD® 1091 primer on chromate conversion coated (MIL-DTL-5541 Type I, Class 3) aluminum substrates.
