Stuart.* As a part of his testing. Dr. Stuart wanted to determine whether the red lead itself was responsible for rust inhibition. To do this he immersed a steel rod in a thin paste of red lead and water foe one hour. The rod was then removed, tlw* oughly washed to remove all pigment nod tested along with an untreated rod The treated rod. although all trace of red lead had been removed, showed decidedly greater resistance to rusting, as measured electrically, than did the untreated rod. Also the protective action, while it steadily diminished, had not entirely disap peared after forty hours. This n shown graphically in Figure 1. Dr. Stuart's interpretation of this result is that red lead forms a thin film at oxide on the metal surface, thus creating a passive state. Kis conclusion, after this . -- W.--- - -JK-trf -r- A-^'i =>-'^A<c=-As33Maf dr^t1' llnsencriisr- M*KaMgMdSHaaMUaU8K3BM^MMlMnMM9M&Mi II m I .u. .J Two members ofthe Bell Telephone Laboratories. H. EL Haring and R. 8.Giboey, have conducted a series of laboratory experiments which seem to confirm this theory of passivity and support their expressed belief that the action of red lead in the priming coat, h essential!y chemical. It Experiments conducted by K. G. Lewis* also show this inhibitnre effect of red lead on metal surfaces. Lewis used the scratch-cont method in which he painted metal with red lead and linseed oiL and when the film wn dry made a standard scratch through H exposing the bare metal. A drop of sodium chloridesolution placed on this scratch and protected against evaporation caused no corrosion, rusting or softening of the paint film in the case of red lead. The reasons for the creation of a passive state on red leaded tnetal surfaces is attributed by some to its baric or alkaline nature. This is on the theory that when sleet Is attacked, the iron goes intosolution at the anodic areas, and the rate of solu Sf tion is inversely proportional to the alkalinity of the medium in immediate contact with the metal. It h further held by other authorities that corrosion is prevented if a protective layer of oxide is formed in direct contact with the metal surface. This takes place when the ferrous sons formed at the anodic areas are quickly oxidized tothe ferric state. Certainly the presence of an active oxidizing agent, such as red lead, will promote the formation of this protective oxide shield and arrest the process of corrosion. Red trad is doubly fortunate in that it possesses in such degree both of these chemical properties which authorities agree are responsible for preetnting metal corrosion. As has been staled by Or. Ulicit R. Evans,* * of Cambridge (England) University.

Of course, the growth of soap crystals it a slow process and a picture which Ukn but a few seconds to show oo the screen must be made over a period of many weeks. Lead Soaps Contribute to Impermeability of Paint Film The formation and presence of lead sosp compounds in a pain film is not merely a chemical curiosity. The reaction hat a very definite practical eScct on the life end performance of thepaint. The composition of the soaps gives a due to one of the reasons that red lead is an efficient guard against such corrosive factors as air and mewtsne. Among the products formed with linseed oil are lead Bnoitme. lead stearate, complex cam* pounds of lead monoxide (litharge) with triglycerides, and basic lead soaps. All of these ere highly water-resistant and unquestionably contribute to low moisture permeability. Confirmation of this is contained in a paper* by Wsofrerf Jfagg; a German investigator. He chsractericcs point films containing red lend "as brick walls, built of comparatively large, impermeable bricks which are bound together with a water-tight mortar.* Further evidence it contributed by mowture perineabiKty test quoted by Bums and Schuh.** The red lead paint film outranked nit ocher pigments tested, bitten in all. so rrartaw:* to ancestor* pssmge through the catting.

The 1941 published report makes the following definite recommendation: "Use a corrosion-inhibiting priming paint, tuch as red lead. Follow this with good weather-resisting finishing coats, tuch as oxide of iron or white lead paints." The report further goes on to explain: The Committee's tests have shown that the most effective of these (inhibitive) primers for general use is red lead.* For many yean similar exposure tests have been conducted under the direction of the Cambridge (England) Laboratory. In these Cambridge tesla, many of the effective combinations involved the presence of red lead in the lowest coat Com* meriting on them, another pa>nt authority, Dr. Ulick R. Evan*,* of King's College. Cambridge University, claims that The Cambridge outdoor tests support the view that the lowest coat should contain an inhibitor-preferabty red lead.* Among the independent authorities who have carefully investigated metal paints of ail kinds are R. M. Bums, Assistant Chemical Director of the Bell Telephone Laboratories and A. E. Sehuh. Director of Research for the U. S. Pipe and Foundry Co l In a recent book,** on which they eollaborated,it is stated "Of all the pigments that hove been used in primers on ferrous metals, red lead has the best over-all record. It has been in constant use for well over a century, and in alt carefully conducted paint studies has always ranked very high. It is not meant to imply that there b no other priming pigment better than red lead, for unquestionably several other pigments have in specific instances given superior protection. However, it b the one priming pigment which has consistently shown up well both in tests and in actual practice.* Paint Research Nations!

Climatic differences are likewise taken into account, the test loca tions ranging from Long Island to Florida, from the east coast to the west Information gathered at these various test stations is continually being drawn upon for the benefit of those who seek help in solving some difficult exposure prob lem or who wish to formulate paints to meet special requirements. Red Lead with Other Pigments There have been many tests a* well as innumerable practical examples to show that the full value of red lead as a protective against rust is realized in straight red lead paints. However, there is also a growing volume of evidence that the strong faihibitive character of red lead and the ability to form useful lead soap compounds increase the protection and length of life of a multi-pigment paint when red lead is included as one of the important components of the pigment phase. Chapter III contains several formulations from established specifications Federal, state and commercial-which call for red lead either aa a single pigment or combined in various percentages withother pigments.Thisis an excellent indication of the general acceptance of red lead for the desirable properties that it provides in metal priming prints. Vehicle Compatibility The formulation of certain types of paints involves the use of vehicle* ocher than linseed oil. In this respect, altboogb essentially basic, red lead is compatible with practically all types of vehicles commonly used in metal priming paints. Far example, varnishes made with afkyd resins, phenolic resins, and modifications of these, os wett as various other mine chlorinated rubber, and different heat treated drying oils, have been successfully used with red lead. Some of the formulas give* In Chapter 111 include a trwof the paint vehicles that are specified Of CMtria. the choice d vehicle usually depends upon the type of service or jaliiih the print is intended.

The remainder is practicallyaltlitharge { FbO) since pure commercial red lead contains only.a fraction ofone percent of other materials. It Is generally accepted that some litharge content is a desirable factor in red lead paint performance. This it probably due to Its bosk nature as sreQ as its ability to form relatively insoluble lead soaps. Red lead with a litharge content of as high os 15*c is employed by some because it combine* quickly with the vehicle due to the increased reactivity. The film ob tained with such a paint also acquires "through- hardness more rapidly than one made with red lead with a higher PbO, content. Becausethe 85** grade fed lead ' combines with the vehicle faster, the paint shook! be applied the same day as mixed. In fact, such paints are generally mixed by wfcting the dry pigment to the vehicle on the jots The 95**, 97% and 98** red leads make faint with good storage properties and for Ms reason are used aimed exclusively for ready-mixed red lead paints. The 95% to generally used in mixed pigment pwiiitt and the higher percentages are preferred for straight red lead paints.
