Abstract

A highly reflective coating painting product, particularly suitable as a coating for integrating spheres, comprises a diffusely reflective product such as, for example, barium sulphate, and an acrylic binder or glue, which are dispersed in a liquid vehicle, preferably constituted by a mixture of water and alcohol. The acrylic binder or glue is a product based on acrylic polymer or copolymer the quantity of which in the coating product is between about 1% and 15%, and preferably between 3% and 4%, by weight, relative to the reflective product. The coating product is applied to a surface in successive layers until a thickness of at least 0.5 mm is reached. The surface coated with the product is then subjected to heating, preferably at about 100° C., for about 1 hour.
