SILICONE ΑΝΤΙ FOAM 60 FOR FASTER DISPERSION

Silicone Potting

Fatty Hydroxamic Acids

A new clear silicone potting and embedding compound that provides mechanical and dielectric protec­ tion for electronic components and assemblies cures at 70° to 80° C. to a flexible, resilient solid. LVT-60Z provides excellent protection against shock, vibration, moisture, ozone and corona, and other en­

Fatty hydroxamic acids may be used as surface-active compounds, pigment dispersants, dyeing com­ pounds, corrosion inhibitors, lubri­ cant additives, flotation reagents, water repellents, metal deactivators, and chelating agents.

Enzyme-Hydrolyzed Soya Bean Protein A low cost, technical grade of a water-soluble, enzyme-hydrolyzed soya bean protein is available as a powder that contains 8.5% total nitrogen of which 20% is amino nitrogen. Called Amber, HSP Series 85, this product is an eco­ nomical source of soya bean pep­ tones, peptides, and amino acids for use in large and small scale proc­ esses. Dept. IEC, Amber Labora­ tories, 3456 Buffom St., Milwaukee 12, Wis. C-5

Faster Dispersions: Low-viscosity G-E Antifoam 60 disperses in­ stantly, can easily be poured. You'll find it more convenient to use and faster-acting than other silicone defoamers. Higher Concentration: General Electric Antifoam 60 comes to you in concentrated form (30% sili­ cones) for easier handling and stor­ age. You can use it as supplied, or reduce it with water to any desired concentration. Greater Economy: Only a few parts per million are needed in most foaming systems, even less than with other silicone antifoams. And because such minute quantities are used, G-E Antifoam 60 will not af­ fect the other properties of your process. • Write for a free test sample, specifying whether yours is an aqueous or non­ aqueous system.

vironmental space-age hazards. Material is flexible, and nonflaming. Components embedded in the material can be readily identified, repaired, or replaced by removal with a sharp instrument. New ma­ terial, poured into the cutout sec­ tion, cures without evidence of repair. Dept. IEC, Silicone Prod. Dept., General Electric, Waterford, λτ. Y. C-2

Metal butoxy hydrides are now available which will reduce acid chlorides to aldehydes. Also useful for reductions of sterospecific ster­ oid ketones to hydroxy derivatives. Company reports that this new product can be easily handled in air and can be stored in screw-top con­ tainers. Dept. IEC, Metal Hy­ drides, Inc., 12-24 Congress St., Beverly, Mass. C-6

Organosol Coatings

Specialty Polyester Resin

A new series of organosol coat­ ings, Sterilkote 360, gives outstand­ ing metal adhesion and requires no priming. lests indicate the onecoat organosols are much more abrasion-resistant than two-coat ap­ plications which do require prim­ ing. Sterilkotes are vinyl resins and may be applied by manual, auto­ matic, or electrostatic spray equip­ ment as well as by regular and reverse-roll coaters. New organo­ sols are highly protective and deco­ rative, and are available in a wide color spectrum which can be ap­ plied in a form applicable to very smooth or textured finishes. Dept. IEC, Bradley and Vroorman Co., 2629 So. Dearborn St., Chicago 16, III. ' C-3

Now available commercially is a new specialty polyester resin, tradenamed Formiez No. 112-R, for the production of solid-cast polyurethane elastomers. Urethanes made from the new resin—a diethylene glycol adipate type—exhibit lowdurometer hardness characteristics and are well suited for such uses as printing rollers and potting and encapsulating compounds. Formrez No. 112-R has a hydroxyl num­ ber of 61, an acid number of 1.9, 0.03% water content, and a viscosity of 15,00 cp. at 25° C. Specific grav­ ity at this temperature is 1.186, and per gallon weight is 9.8 pounds. Dept. IEC, Witco Chemical Co., Inc., 122 E. 42nd St., Neiu York 17, N. Y. C-7
