For more durable c o a t i n g s formulate with silicone resins Start your formulation with these Dow Corning resins and copolymers and you're sure to produce finishes that last longer, cut maintenance costs, assure user satisfaction. You can even pre-determine the degree of heat stability, weather resistance, gloss retention, or other properties needed to meet the requirements of specific applications.

In maintenance coatings where heat may be a problem, Dow Corning 805 and 806A Resins provide lasting resistance to 1000 F when blended in aluminum formulations. Such paints are excellent for use on stacks, mufflers, boilers, jet engines, exhaust manifolds and other hot spots. Where painted areas must maintain color at temperatures up to 550 F, your choice should be 808 Resin. You'll find coatings made with 808 Resin resist fading and chalking . . . lengthen the time between repaintings. And if you're interested in air-drying silicone organic copolymers, note that Dow Corning also offers silicone intermediates . . . you can enjoy the economies of cooking your own vehicles.

Product finishes, too, are better when you start with silicones. In this field, Dow Corning R-60031 silicone-alkyd copolymer helps in formulating decorative finishes that hold color and adhere well at surface temperatures as high as 450 F. Finishes made with this copolymer are ideal for space heaters, clothes driers, stoves, other hot appliances. When temperatures

rise to 550 F, Dow Corning 804 and 808 Resins are recommended.

You make better finishes when you start with the Dow Corning silicone resins and copolymers listed above. For more specific information, write Dept. 1916.
