Cho-Shield 2002 Corrosion Resistant Electrically Conductive Coating ABC 3 Part Kit
Parker Chomerics CHO-SHIELD 2000 Series electrically conductive coatings provide a corrosion resistant conductive surface coating on aluminum or composite substrates. The CHO-SHIELD 2002 coating, mainly intended for composite substrates or as a 2001 repair coating, is chromate-free.
Product Properties
Product Information
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.
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°C (70°F) followed by 30 minutes at 121°C (250°F).
