MULTISPECTRAL TAILORABLE COATINGS

Abstract

A coating comprised of a broadband transparent binder and multilayer thin film particles is applied to the surface of an object. Each particle has a flat principal surface and the dimensions of the particles are selected so that the flat surface of essentially every particle will align parallel to the nearest portion of the object surface to the particle. There is a leafing or an overlap of the particles parallel to the object surface. The particles form a continuous conformal coating over the object surface. It is preferred that the maximum dimension of the principal surface of each particle be at least 30 microns and, for best results the maximum dimension should exceed 50 microns. Metallic flakes and/or flakes or particles comprised of organic dyes may be included in the coating to further tailor its spectral characteristics. It is preferred that the weight of the particles equals 20 to 40% of the weight of the combination of the particles and the binder.
