D u Pont Estersil G T (grease thick ener) can help you make a better grease . . . one that has outstanding advantages you can sell. 1. Excellent shear stability—Even under severe high-shear, high-temper ature operating conditions, greases made with estersil G T show excellent resistance to t h i n n i n g for long periods of time. 2. Water resistance—Each minute estersil particle is protected by a chem ical "raincoat." This gives estersil greases built-in water resistance . . . helps eliminate the danger of washout even under drastic water conditions. 3 . Unusual thermal stability—Ester sil greases are nonmelting. Even ex tremely wide temperature ranges pro duce little change in consistency. 4. Superior oxidation stability—Es tersil greases are almost as stable as their base oils and need no antioxi
dants under most service conditions. 5. Superior handling q u a l i t i e s — Greases thickened with estersil G T can be more easily handled in almost any application. This is because their un usually satisfactory thermal and me chanical stability permits use of a much softer grease. 6. Easy to m a k e — A milling opera tion is all that is required to manu facture estersil greases. D u Pont Estersil G T is available in commercial quantities.
