if Wtqarnmm iSA-D "Soaps" ... check Rusting 3 Ways Scientific research shows why Red Lead has fong been regarded as the"starnhiri3" metal-protectivfe paint. One interesting factor is Red Lead's ability to react with the vehicle and prodace unique lead "soaps," These "soap" formations growto-form a tough, imperyiotis, intermeshing matrix within the paint film, as shown in the photomicrographs below. These "soaps" help Red Lead inhibit rust three ways. 1. toughen Paint Film. Radiating from central cores the"soap"formatians develop long, rod-like projections, which spread out and interlock. Thus, they form a dense jntfermeshing structure that mechanical ly reinforces and toughens the paint,film. 2. Matte Rim Water-Resistant The very, struc tural formation of these "sdaps," with their illicit, impervious matrix of closelyknit fibres, helps restrict the passage of moisture 'through the paint film. And metalcannot riist without the presence of moisture. 3. Keep Film flexible. The "soap" formations, far from being rigid, allow movement all along their sojfe intertwining projections. The resulting' flexibility helps prevent the ruptures to which a hard, unyielding paint film is subject. Thus the lead "soaps" aid'in maintaining the continu ity of the paint film. Lead"soaps" form primarily in the dry paint film as it ages. This is where the "soap" formations impart their greatest benefits:. When a paint film weathers, and ages, decomposition products of the-ve hicle .afe,formed. Red Lead's ability to slowly combine with these decomposition products Actually enhances the life of the paint film.' Red Lead's slow rate of re action jn^ans the film age-hardens at a slower r^to. It thus retains a high degree of flexibility, a great factor in its lasting adhesion. The photomicrographs above show how Red Lead "soaps*' progressively spread out os they grow and (Jills reinforce the paint film. Remember, too. Red Lead is compatible with practically all vehicles commonly used in.metal protective paints, includ ing fast-drying resin types. REG LEAD Improves ALL Beta} 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. The benefit of o u t extensive experience with metal protective paints for both underwater and atmospheric use is available through our technical staff.
