The coating of having the capability of reflecting solar heat is the requirements of the world of saving energy. This kind of coating can reduce the need of electronic and water power besides protecting and decorating the covered objects. The gray color coating with insulating heat and lowering temperature is one of the most difficult topics. In this research, on the basis of choosing reasonably resin,pigments and fillers and assistant agents , a kind of special gray coating is obtained. It can obviously lower the temperature of coated objects in comparision to the common gray coating. Its refletivity can be up to above 50% to solar light.
