Genamid 250 and 310 are new fluid resinous amine adducts developed to satisfy the needs of the formulator. They are the latest products of General Mills continuous research in improved epoxy-reactive polymers. These low viscosity co-reactants provide easy blending with fluid epoxy resins. I n addition, higher filler ratios can be used t o reduce formulation costs. Genamid 250 a n d 313 are especially designed for coatings, adhesives, casting, potting, laminates a n d other applications where their specific properties offer outstanding advantages.

P O T L I F E — B l e n d s of Genamid a n d epoxy have 50-75 minute pot life a t room temperature with low exotherm—can b e used economically for bulk casting. C U R E T I M E — A t room temperature, Genamid and epoxy cure t o near optimum properties in 6 t o 8 hours; t o maximum properties within 24 hours. At elevated temperatures, complete cure can be achieved under 15 minutes.

Fifty miles southwest of Death Valley, California, West End Chemical Company, a Division of StaufFer Chemical, is recovering sodium carbonate crystals from the brines of Searles Lake (an underground lake in t h e desert). The raw brines from this lake are carbonated to precipitate NaHCOa, which is classified and thickened in Dorr Classifiers t o 25-30% solids prior to dewatering by the Oliver Salt Type Filter shown above. This 6' dia. by 6' face Oliver Filter is one of three identical stainless steel units in use on this product. (Note the high capacity 2 8 " dia. valve on the right hand side of the photograph.) The sodium carbonate is then calcined t o soda ash, a basic chemical used in the manufacture of soaps, glass, and many other consumer products. This recovery process is unique, as t h e spent liquor remaining after processing is returned t o the lake. Thus, the laws of nature provide a continuous closed circuit processing operation. If you have a problem involving liquid-solids separation, Oliver Filters should rate as your number one consideration. Complete information on Rotary Drum Filters for the processing industries may be obtained by writing Dorr-Oliver Incorporated for a copy of Bulletin No. 720O.
