ABSTRACT:
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 Co.sub.3 O.sub.4, CuCr.sub.2 O.sub.4 or Cu.sub.x Co.sub.3-x O.sub.4 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.
