  • COATING COMPOSITIONS, LAYERS, AND SYSTEMS FOR RADAR TRANSMISSION AND METHODS FOR MAKING AND USING THE SAME
    Publication number: 20220325109
    Abstract: A coating composition, a coating layer, and a coating system, and a method for making a and using the same are provided. The coating system comprises a flop index of 2 or greater and comprises a coating layer formed by a coating composition. The coating composition comprises a film-forming resin and a pigment composition. The pigment composition comprises 50% or greater by weight radar transmissive pigment based on the total weight of the pigment composition and no greater than 50% by weight electrically conductive pigment based on the total weight of the pigment composition. The coating system has a radar signal transmission of 70% or greater. The coating system has a CIELAB color difference, ?E, compared to a color-matched coating system of no greater than 4, as measured at 110°, using a multi-angle spectrophotometer with D65 Illumination and 10° observer.
