Abstract
(EN) Radar transmissive pigments, coatings, films, articles, method of manufacture thereof, and methods of use thereof are provided. The pigment comprises a non-conductive composite. The non-conductive composite comprises a semiconductor and/or a dielectric, and a metal dispersed in and/or on the semiconductor and/or dielectric. The pigment has an aspect ratio of at least 5 as measured by the Aspect Ratio Test.
(FR) L'invention concerne des pigments, des revêtements, des films, des articles transmetteurs de radar, leur méthode de fabrication, et leurs méthodes d'utilisation. Le pigment comprend un composite non conducteur. Le composite non conducteur comprend un semi-conducteur et/ou un diélectrique, et un métal dispersé dans et/ou sur le semi-conducteur et/ou le diélectrique. Le pigment a un rapport d'aspect d'au moins 5 tel que mesuré par le Test de Rapport d'Aspect.
