METHOD OF FORMING A LOW SPECULAR REFLECTANCE SURFACE

Abstract:

A method for making a low-specular-reflectance coating composition, includes providing a plurality of batches of substantially spherical particles including a first batch of particles having a first single mode particle size distribution with a peak corresponding to a first particle size, and a second batch of particles having a second single mode particle size distribution with a peak corresponding to a second particle size. A ratio of the second particle size to the first particle size is between 1.7-4.0. A binder and a solvent are provided and are combined with the plurality of batches of particles and mixed to form the low-specular-reflectance coating composition. A volume percent of the particles is between 2-30 volume percent, a volume percent of the binder is between 1-25 volume percent, and a volume percent of the solvent is between 45-97 volume percent.
