Abstract
This invention relates to an electrically conductive white coating of the paint type, which has a solar absorption .alpha..sub.S not greater than 0.30, a hemispherical emission factor .epsilon. not less than 0.80, a surface resistance R.sub.S, measured in a vacuum less than 10.sup.-5 torr, not greater than 10.sup.9 ohms/square, and which meets the degasification-pollution requirements, characterized in that the coating comprises (a) a layer which is a good conductor of electricity and (b) a white layer which is a poor conductor of electricity and which is applied on top of layer (a). The coating is for use in the space and aeronautical industries.
