Claim 2
Dependent Claim
67 words
A diffuse gray coating mixture having a low infrared emittance and comprising by weight: from about 10% to about 22% coarse non-leafing aluminum powder; from about 2% to about 15% cobalt metal; from about 2% to about 5% cobalt oxide; from about 7% to about 20% titanium dioxide; from about 65% to about 75% silicone alkyd resin and from about 1% to about 4% polarized montmorrilite clay.
Claim 3
Dependent Claim
17 words

Claim 4
Dependent Claim
23 words
The coating mixture of claim 1, wherein the particles of said coating mixture have a particle fineness of less than 6 Hegman scale.
Claim 5
Dependent Claim
95 words
A diffuse gray coating mixture having a low infrared emittance and comprising by weight: from about 10% to about 22% non-leafing aluminum powder; from about 2% to about 15% cobalt metal; from about 2% to about 5% cobalt oxide; from about 7% to about 20% titanium dioxide; from about 65% to about 75% silicone alkyd resin and from about 1% to about 4% dispersing agent for suspending the pigment materials of aluminum powder, cobalt metal, cobalt oxide and titanium dioxide in the silicone alkyd resin and preventing said pigment materials from settling out of suspension.
