2 Ways RED LEAD NEUTRALIZES ACIDS ...Retards Rusting Those responsible for making metal last have long accepted Red Lead as the "standard" metal protective paint. Now scientific research discloses sound rea sons why Red Lead gives plus: protection. For example, one important factor Is Red Lead's ability to,counteract the held conditions which accelerate resting. Red Lead accomplishes this in two Ways. 1. Red Lead Counteracts^EnvIremneniar Acids: The uses to which structural steel is put normally expose it to acid environments. Fo e one thing, it is usually subjected to the attacks of indus trial gases and smoke. Certain of these, in contact with moisture, produce acid-forming compounds that speed up rusting. Then, too, pollution of waterways also, result? in acidity. Red Lead effectively neutralizes all such adds, and thus counteracts their rust-accelerating effect. 'l Z- Red lead Controls, fo&erent Acids; Many paint vehicles,! such as lihseed oil, synthetic resin varnishes and other commonly used types, themselves produce; organip acids during the natural process of ageing. Many of those, in herent acids, too, hasten corrosion., However, when Red Lead is' the pignient !in a , metal protective' paint, this rust-ca'iising acidity is KD .4019B--Corrosion, April, 1947 k kept in chjck. Thus, a "controlled" acid level Is maintained ia the paint film. This is a singular property of Red Lead and contributes greatly to its film flexibility, impermeability and long life. Remember that Red Lead Is compatible with practically all vehicles commonly used in metal protective paints, including, the fast drying resin types. Specif/ RED LEAD far,ALL Metal Protective Paints The rust-resistant!properties of Red Lead are so pronounced that it improves any metal protective paint. So', no matter wha price you pay, you'll get a better paint if it contains Red Lead. WRITE FOR BOOKLET: "Red Lead in' Corrosion Resistant Faints.'" Address nearest;branch.
