AZ-2000-IECW is an inorganic conductive white thermal control paint developed for use on spacecraft and satellite surfaces exposed to the deleterious effects of the space environment. This paint is designed to be deposited onto large complex surfaces with minimal difficulty or environmental impact to form a non-specular coating that maintains optical and electrical properties when exposed to the space environment. It possesses several orders of magnitude greater electrical conductivity than currently available thermal control coatings while providing atomic oxygen protection and surface charge dissipation for spacecraft and terrestrial applications.
The table below lists the optical and application parameters of cured AZ-2000-IECW.
