Overview
Parker Chomerics CHO-SHIELD® 2000 Series electrically conductive coatings provide 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 particular 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, they provide the conductivity necessary to achieve excellent shielding effectiveness while maintaining their electrical and mechanical stability in hostile environments. CHO-SHIELD® 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. In addition, CHO-SHIELD® 2001 and 2003 contain soluble chromates to minimize the effects of galvanic corrosion of the aluminum substrate, even in the event of a coating scratch. The CHO-SHIELD® 2002 coating, mainly intended for composite substrates or as a 2001 repair coating, is chromate-free. CHO-SHIELD® 2003 is a dark pigmented version of CHO-SHIELD® 2001. The CHO-SHIELD® 2001 and 2003 coatings are designed to be used with CHO-SHIELD® 1091 primer on chromate conversion coated (MIL-DTL-5541 Type I, Class 3) aluminum substrates. CHO-SHIELD® 2002 is designed to be used with CHO-SHIELD® 1091 primer on non-aluminum substrates such as MIL-P-18177 glass-filled epoxy composites and will typically deliver 0.1 ohm/square surface resistance when cured for 2 hours at room temperature 21 degrees C followed by 30 min at 121 degrees C.
