ABSTRACT OF THE DISCLOSURE Postformable solar selective coatings are disclosed for use on substrates such as aluminum. The coatings use a finely divided black inherently selective spinel pigment such as Co3O4, CuCr2O4 or CuxCo3-xO4 where x is 0.03 to 0.3 and preferably 0.10 to 0.30. The binders are soluble copolymers of vinylidene fluoride or blends thereof or vinylidene fluoride with a copolymer of methyl methacrylate.
