ARMIDS® HELP SOLVE NEW PRODUCT DEVELOPMENT PROBLEMS In working on many complex surface coat ing problems, the answer seems to lie somewhere between waxes and plastics. Many of today's plastics are incompatible with and insoluble in the cheaper and more plentiful waxes, such as paraffin and microcrystalline. Due to their unique mu tual solvent properties, the Armids — Armour's high molecular weight, wax-like, fatty acid derived aliphatic amides-pro vide an economical and effective solution to many such problems. As mutual solvents, the Armids are soluble in a number of modern plastics, but still more important, they permit the plastics to tolerate quantities of petroleum waxes. When these waxes are blended with plastics, the manufacturer can choose a surface that is soft and wax-like or hard, flinty and plastic-like. The Armids have proved useful in many other fields besides surface coating. Arm id HT is a good example. By incorporating small amounts of this Armid into molded rubber formulations, in place of one to two parts of carnauba wax, good appear ance and high sheen are added to such quality molded rubber products as sink drain mats, car rugs, footwear, garden hose, etc. Because of the relatively lower cost of Armid HT, considerable savings result from its substitution for carnauba. Armid H T is also being used in the molding of simulated wood products. Here it acts as an internal mold release agent, resulting in smoother moldings, finer re production and greater detail of irregular surfaces, as well as better mold release. In printing inks, Armid HT and Armowax — a high-melting, hard, brittle wax with very interesting compatibility char acteristics—can provide some very desir able results. Armid H T is an extremely effective antioffset, non-scratch agent. and : when added in small amounts, results in scurf-proof inks which do not have a tendency to rub off. Also, Armid HT can be used as a viscosity control agent to improve the body or consistency of the ink. Armowax contributes hardness and gloss to dusting resin-powder mixes, ac cording to recent field reports. This powder is dusted over printing that is still tacky. The paper is then subjected to heat, and the result is a hard, glossy ink that has the feel and appearance of embossed print.
Another anti-block agent — Armid C — is used for vinyl polymer type lacquers. When these lacquers are used in paper coating, it is essential that the final coat ing dry tack-free, or the resulting rolls or stacked sheets will stick together, render ing them unusable. Approximately 5' , by weight of Armid C eliminates any possible tackiness. Armid C also is used as an ideal thickening agent for inflammable-type paint and varnish removers. Armid Ο can be used as a dip or spray protective coating for such metals as brass and copper alloys as well as parts plated with precious or semi-precious metals. The Armid provides a simple, in expensive and efficient means of protec tion from such dangers as fungi growth and tarnish from fumes like hydrogen sulfide. Armowax has been found superior to the stéarates normally used as binders in the moldmg of powdered sintered metals. This is due to the high melting point of Armowax. It acts as both a binder prior to fusing and also as a die lubricant. Considerable reduction in the wear of the dies results from the use of Armowax. Its high melting point is also the reason Armowax can be used to improve the wax coating usually required on electrical equipment such as condensers and capacitors. The heat of normal operating temperatures will not soften or melt this wax. Send the coupon for our new free booklet on these versatile chemicals. Solubilities, compatibilities and other ^h^sical data are discussed at greater length as well as other pertinent use-data.
DUOMEEN® SALTS AS BACTERICIDES AND FUNGICIDES Salts of Duomeen C and Duomeen 12 have shown considerable promise as bactericidal and fungicidal agents. The Duomeens are strong organic bases, due to their double amine groups, and exhibit greater cationic properties than their corresponding primary amines. Duomeen C is derived from coco fatty acids, and Duomeen 12 from lauric acid. Their salts are soluble or dispersible in.water.

LONGER-LASTING, FASTER-DRYING, NON-YELLOWING ALKYDS WITH NEO-FAT® 140
Nothing looks neater than a newly painted house. But often the paint begins to yellow and age prematurely, and the homse loses its clean look. The good effects are lost due to certain defects inherent in the psint itself. A new answer to this problem is Armour's improved Neo-Fat 140 (formerly 3R) —a fatty acid material produced by a new low-temperature solvent crystallization process. When used to formulate alkyd resins, Neo-Fat 140 gives fasterdrying, non-yellowing finishes. Its lower titer means that it can be exposed t o temperatures as low as 5°C. without any solidification. High iodine values and low saturated fatty acid content yield more double bonds per gallon of fatty acids, giving better dry and harder alUyd resins. Faster processing time and brilliant color which carries over into the finished product are other important advantages of Neo-Fat 140. It also offers good flexibility in baking finishes, even a t 50°F\ For further information on this improved fatty acid material, send the coupon for Armour's Technical Bulletin A-l, which gives complete data, including formulas.

USES
The availability of Armour's high purity myristic acid provides a new raw material for the synthesis of organic compounds. Alcohols, nitriles, amine esters and metallic soaps may be produced easily and find in numerable applications. Many references have been made in recent literature to the use of various Neo-Fat 14 derivatives in detergents, dyecs, textiles, wetting agents, lubrication oils and greases and other industrial applications. The monoglyceryl ester of myristic acid is a substitute for coco butter in supposi tories and as a super fatting agent for soaps, creams, lotions and similar products.

The Armour Chemical Division's patented fractional distillation process has provided many new materials which have led to the development of new and improved prod ucts. An outstanding example is Neo-Fat 14 —a commercially pure myristic acid. Myristic acid occurs naturally as the glyceride in various vegetable oils and fats. It is a hard crystalline substance fall ing between lauric acid and palmitic acid in the saturated fatty acid series. Com mercially it f is available as Neo-Fat 14 with oyer 94 "( pure myristic acid content and only traces of lauric and palmitic acid.
