CYANAMID To: H . C. Gaffney Location: Chicago Plant From: J. F. Daly Location: Chicago Plant Extension: Date: 2/24/84 Copy to: R. Johnson J. A. Stretanski F F. Loffelman Subject: MONTHLY REPORT FOR FEBRUARY, 1984 Reference: A. TECHNICAL PROJECTS 1. PPG At the urging of PPG we have made an effort to im prove the Hegman grind of Cyastab 40. As a result, oil absorption values increased to unacceptable levels. A meeting was held with PPG research and plant per sonnel at their Allison Park, Pa., research center in an effort to resolve the question of exactly what PPG needs and what we can supply. Ultimatley, PPG needs material that will pass their salt spray test. Since this isn't a practical QC test, they have tried to find other para meters which would correlate with salt spray. At this point they believe that oil absorption and chemical com position (ratio of 4 PbCC>3.2 Pfc (OK)2.PbO to 2Pb CC^.Pb (OH)2) affect salt spray, but the. data seen thus far is far from conclusive. They therefore want material with a maximum oil absorption of 15 and a composition of at least 68% 4 PbC03.2 Pb (OK)2.PbO. Since Hegman grir.c does not affect product quality, only production time, they are willing to relax the grind specification to a 4 A minimum. We also discussed setting up a joint research project to study the effect of various stabilizer properties on salt spray. Cyanamid will provide samples cf stabilizer with as wide a variation in oil absorption, chemical composition, etc. as possible, and PPG will run salt spray and x- ray crystallography (for composition).

TENNECO We have established that Cyastab 523-0 supplied 1 year ago to Tenneco has the same electrial properties as the material they are complaining about, and the difference between Cyastab 523-0 and Tribase XL- oiled is very slight. Accordingly, their complaint is not justified. We will need considerably more information about Tenneco's application before we can do anything about developing a stabilizer that will perform in this spec ific application. B. PLANT GENERAL 1. COMPUTER The energy and labor useage program has been de signed and installed. We will begin testing on March 1. Testing and "debugging" of the inventory program is proceeding satisfactorily. C.
