These 3 New With Developments A R E RELIEVIXCi HAW MATERIAL SHORTAGES IX MANY PLANTS
WITCO YELLOW A new synthetic pigment, Witco Yellow offers interesting possibilities for replacing* French Ochres in rubber and paint manufacture. \\ hile practically the same in analysis as French Ochre, it provides these outstanding advantages: Greater strength Higher tinctorial value Cleaner final tint
P E R H A P S W E C A N H E L P YOU T O O ! W i t c o Yellow, a replacement for French Ochre; Witco Blancal, an alternate for Blanc Fixe; Witcarb, an improved calcium carbonate—these three new products of W ishnick-Tumpeer research are not only relieving current raw material shortages in many applications, but are finding a permanent place in manufacturing techniques. For these products are not merely ' r subst^tutes , ' , born of an emergency: they are definitely superior in manv respects to the materials they replace. These three developments offer convincing demonstrations of the skill and resourcefulness of \ \ ishnickTumpeer's staff in dealing with raw material problems. T h e Research Laboratories of \\ ishnick-Tumpeer are thoroughlv equipped to undertake such problems, particularlv in the fields of chemicals, oil, pigments, asphalts, and allied products. If v o u are faced with a shortage of raw materials essential t o your production — or if new manufacturing conditions require modification in the properties of other materials—perhaps you, too, can benefit by WishnickTumpeer's technical cooperation. Write, wire, or phone us an outline of your problem—what materials you need, what properties they must have, how they are to be used. Let our experienced research workers assist y o u in the effort t o develop alternate or improved materials that mav provide a satisfactory- solution to your problem.
WITCO BLANCAL This precipitated barium-calcium compound is available in both low and high oil grades as an alternate to Blanc Fixe. In most cases, it gives better results than Blanc Fixe, since it offers you these desirable characteristics: Kxtremely fine division Kxcellent color, in dry state as well as under oil Higher bulking value
WITCARB This new inert offers special advantages as a white reinforcing fillei in rubber formulas requiring high tensile and modulus. In paint formulas, it provides such features as: Lower cost per pigment pound More gallons per pound Added texture in flats Better stability in finished product I m p r o v e m e n t s in Lithopone and Titanated Lithopone paints, and in some cases gloss paints and enamels Samples and complete information on any of these new products will be sent on request.
