MnSO4 Tecmangam (Technical manganese sulfate) Manganese sulfate (equivalent (equivalent
to manganese oxide to metallic manganese
Ammonium sulfate (equivalent
75-78% 35.23-36.64%) 27.28-28.38%)
11.7-12.5% to nitrogen
2.50-2.63%)
We've been manufacturing Tecmangam for years for use in fertilizers, nutritional sprays and feeds to insure an adequate manganese level in plant and animal nutrition. It's completely soluble in water, it's low in cost—so why not a source of manganese for chemical synthesis, too? Sold in 50-lb. net, 5-ply paper bags. Send for a sample and try it.

T E P (Triethyl Phosphate) Form liquid Specific gravity, 20°/20°C 1.067-1.072 Boiling range 97% betiveen 209-218°C. Ester content, % min 97 Here's another chemical we've made for a number of years, one that is surprisingly versatile. It's a non-corrosive solvent. It's a mild ethylating agent. It's an intermediate, being used to make tetraethyl pyrophosphate, a powerful, fast-acting insecticide. It's a catalyst for ester syntheses and for certain polymerizations. But then we've talked about these uses before. Here's a brand new one—a lacquer remover that does a remarkable job of separating the sheet from the coats. Some of its advantages follow: A w a t e r s o l u t i o n . No wax, no other organic solvents. Effective in removing butyrate, nitrate, and acrylic lacquers. E a s y t o u s e . Softens but does not dissolve film. Leaves no residue. Remains wet for hours. Softened film flushes from surface with water. S a f e . Non-flammable. Low in toxicity.

Half-Second Butyrate/Resin Combinations Having just completed a comprehensive investigation of the subject in our Coatings Laboratory, we learn that a number of important resins not often considered in the formulation of Butyrate coatings can, in fact, be combined with Half-Second Butyrate. We suspect this work to be of first importance. For a detailed report on the resin combinations mentioned below, including formulations, return the coupon. H S B / A m i n o . Crosslinking, giving increased adhesion, toughness, heat and solvent resistance. Improved sprayability and flowout. Faster air-dry. Outstanding weathering. H S B / E p o x y . With Butyrate-epoxy-amino formulations, better storage stability. Increased adhesion, toughness, and flexibility. H S B / P o l y u r e t h a n e . Better flow characteristics and improved build, using EAB-381-20, a higher viscosity Butyrate resin. H S B / S i l i c o n e . Improved outdoor durability and gloss retention of Butyrate. H S B / A c r y l i c . Better sprayability and solvent release. Higher solids content. Increased weather resistance and gloss retention. Excellent alkali resistance. Adhesion to aluminum. H S B / M a l e a t e d v i n y l . Improved initial adhesion and toughness of Butyrate-acrylic films. H S B / P o l y e s t e r . Better leveling. Shorter tackfree time. H S B / O i l - f r e e a l k y d . Improved adhesion and toughness. E a s t m a n C h e m i c a l P r o d u c t s , Inc. Kingsport, Tennessee B27
