FIELD: protective materials. SUBSTANCE: composition for protective coating contains potassium silicate solution with modulus 3.5-4.0 (silicate binding agent) as a binding agent and magnetite. Combination of components taken in the definite ratio allows preparing coating with high absorbing capacity, stability of optical indices and high strength indices. Composition is used as thermal regulating coating of class "true absorber" in application on external, mainly radiation surfaces of the space object. Composition can be used for creation of contrast images, for example, approach targets, for applying different labels and inscriptions on external surface of space objects. EFFECT: valuable properties and indices of composition. 1 tbl, 5 ex
