vYtf Thousands of tests, under all kinds oj. service conditions, prove that "Dutch Boy" Red Lead gives metal extra protection ft Ways KAdmi LEAD RESISTS EFFECTS OF WATER ...guards against Rust lainlonanco engineers have long recoglizcd Ked Lead as the "standard" metal irotcctlve paint. This acceptance isbased, it a great extent, on its marked ability to land lip against moisture, a powerful actor in the rusting process. Now, scientific, research into the inicrent properties of the pigment itself, hows just how and why Red Lead rcists the effects of water. Briefly, there rc four reasons: .. ftetf Lead resists water "pick-op"--If a seics of various metal protective paint ilms are weighed and then submerged in rater (salt or fresh), it is readily noticed, n reweighing after several days immerion, that Ked Lead films have outstand- rating W atcr Permeability of biintf'ilnu -- U ilh (his standrd apparatus a measure oj he amount of scaler that n<ses through a unit of film t obtained.

Red Lead. ing resistance to the absorption, or "pick up," of water. j 2. Red Lead resists passage cf moisture--Rust ing of metal will not take place if water does not penetrate the paint film to reach the metal. Water permeability tests of paint films (see illustration at lower left) show, beyond question, that Red Lead is one of the most effective metal protective pigments, because of its stubborn resis tance to the passage of moisture through the film. Remember, too, Red Lead is compatible with practically all vehicles commonly used in metal protective paints, including many of the fast-drying resin types. RED LEAD Improves ALL Metal Protective Paints The rust-resistant properties of Red Lead are so pronounced that it improves any metal protective paint. So.no matter what price paint you want, you'll get a better paint if it contains Red Lead. 3. Red lead resists solution by witer--The ac tion of water on paint films results in a partial dissolving of the film. Many metal protective films loseia considerable per centage by weight of their films through The benefit of our extensive experience with metal protective paints for both underwater and atmospheric use is available through our technical staff. solution in water. On the other hand, the solubility losses of Red Lead paint films are practically negligible. 4.
