SORBITOL PAINT RESINS ARE ECONOMICAL ... PRODUCE SUPERIOR FILM CHARACTERISTICS Sorbitol, a hexahydric alcohol derived by Atlas fro"m the reduction of glucose, offers specific advantages of quality and economy in the formulation of certain resins used in protective finishes.
SORBITOL RESINS?
In the preparation of oil-modified alkyds, sorbitol is generally used in combination with other polyols. I t imparts faster airdrying and baking characteristics, and produces films with greater toughness. The ratio of sorbitol may be varied over a considerable range to give desired effects. Most frequently used proportions are from 40 to 50 per cent. Rosin esters of sorbitol, prepared by reacting the rosin acid with an excess of poiyol, give a broad field of usefulness.
AVhen modified with maleic anhydride, for example, they develop hard, high melting resins that find use in both lacquers and varnishes. Tests indicate t h a t lacquers containing sorbitol resins possess an excellent balance between sanding properties and cold check resistance. Whether used by itself or in conjunction with other polyols, sorbitol affords economies due to its low, stable price. A number of formulas for sorbitol-based resins have been worked out in the Atlas laboratories. These are listed, along with procedure for preparation and physical characteristics, in a booklet entitled "Sorbitol Resins." We'll be glad to send a copy on request.

N e w method for shipping Hystrene® fatty acids High-purity Hystrene hard saturated fatty acids are now supplied in labor-saving palletized units of forty bags each. Each group of bags is a firm, compact unit on a disposable paperboard pallet. The unit can be picked up on a fork lift and moved intact... as shown in the illustration. A full car-load can be unloaded in a fraction of the time that used to be required. Storage space is saved, because the neat pallet units stack tightly together in minimum floor space. Write today for our new folder which lists complete specifications for Hystrene and Industrene® fatty acids, and shows how this new shipping method will help you. 2397
