the "FRIED EGG" test* why house paints containing "LEAD" have extra durability The "Fried Egg" test is an interesting and striking comparison of the oil retention properties of a paint film. This simple ex periment is carried out by dropping a con trolled quantity of paint on a piece of filter paper and observing the area stained by the oil released from the paint. From the illustration, it can be clearly seen that non"lead" paints give up considerably more of the oil vehicle than those containing substantial portions of white lead. The faculty of white lead to retain the oil in the paint film is a prime requisite of durable house paint films. Without lead pigments, more of the oil binder tends to penetrate the wood or other porous sub strata, robbing the oil from the protective film -- with consequent early erosion or severe chalking. Oil-retention is but one of the several reasons why white lead is so desirable in paint. Use enough of it to take advantage of all the qualities that lead pigments im part. You as the manufacturer will know you are producing a better--more reliable product. And white lead pigments in paint can't be beat as a valid argument to pro mote sales. Valuable Reference Material: Write for data sheets on paint formulations to meet specific end requirements. Lead Industries Association, 420 Lexington Avenue, Sew York 17, S. Y. r Photograph of laboratory test aptly described as the "Fried Egg" test because of resemblance of the end result to an egg fried "sunnyside up." * Federal specification TT-P-141b, method 442.1 -- absorption test. "LEAD" LENGTHENS THE UFE OF PAINT BECAUSE: # It Stabilizes--neutralizes acidic compounds resulting from the decomposition of die vehicle--prevents the film from becoming soft or liquefying. It Flostkizaj--forms lead soaps which increase film flexibility. It Strengthens--flexible, spiney crystals in lead soaps mechanically reinforce the film and Increase elastic strength. K ft Resists Water --paint films with an optimum lead pigment content absorb only a small fraction as much water as they otherwise wonld. ' It limits Oil Penetration--more of the vehicle remains in the film where it is needed; less is absorbed in the substrata. ft improves Appearance--by controlling chalking and inhibiting mildew. . .^ LIA02964 This advertisement appeared in May 28 and June 25 issues of American Paint Journal, the May issues of Official Digest, Paint, Oil flfc Chemical Review, Western Paint Review and Paint Si Varnish Products.
