Watt - cw V Fbrraulaa for our nee acoustical plaster are being sent to ; m, with the exception of Hr* Read, who already has the formula* Raw materials specifications will be Issued in the near future* Until that time purchases can be made from the following! 1* Bentonite CJsy - l$ro-0el 200 mesh high gelatinizing grade George A. Rowley & Co., Philadelphia, Pa.'color - no darker than standard. 2* Asbestos - 7D - Must not be pressure packed Philip Carey & Co* 3* Perlite - Our own material. L. Tatra Sodium Pyro Phosphate (small pellets) at least 75$ rrinm* 20 mesh* Monsanto Chemical Co* 5. Ultrawet BS - Atlantic Refining Co* The Bontcnito Clay is a perishable item* Ion should not stock over a 90 days supply* Do not nako any acoustical plaster except for orders as the clsy deteriorates faster when in the finished product, until wo know more about how fast it will move* Port Bodge ordered raw materials the latter part of February and to ry knowl edge have not yet shipped any acoustical piaster to date. With this in mind it seems that .cur raw materials supply should be kept at a minimum until the material starts to novo, especially the Bentonite Clay. Present plans are for each plant to stock raw materials necessary to make 20 tons of acoustical plaster* This may present a problem as I believe minimum truckload of lyo-Gel Bentonite is 16 tons and 20 tons is a minimum carload of asbestos. Quantities less than this may be prohibitive from a price standpoint* In any event we are not authorised to say what quantities of raw materials should be ordered. Will Mr, Grieve and/or Mr* Trolley please advise* *** I SGP 0018799
