York Roy and Joe first discussed their great interest in the RG-244 and are greatly surprised that it's use isn't larger than the approx. 900# per month they are using now. . 1971 Roy was told of the various normal safety respiratory devices to be used in han ling the Calidria safely. Dennis York, the Plant Safety Engineer, needs information to satisfy the APCD. This should be similar to that published by Cabot. Union Carbide will soon be publishing information that he could submit the Los Angeles APCD. He was also told that Asbestosis and Silicosis were equally dangerous if proper safety precautions were not taken. Thb allowable dust levels per cu. ft. were discussed and how to assure safe handling in this respect by proper respiratory equipment and air ventilation. (\ . Call made with R. Larkin and R. Byrne, ai ru J eff Rittenberfe Cargill September 13, 1971 Interviewed: J. Su I ke ' . H. Nakano Jack and Hank said they might be detecting a color darkening in some products using RG-244, which seems unaccountable to all of us. Jack also said that he has to use more RG-244 than he should to get his vis and thix index. Their lab is awaiting a Cowles mixer so a 2 drum batch can be made. Wealsc discussed their use of 1/4 Cabosil or a touch of Ti(L t0 get the necessary appearance in the resin that their customers are accustomed to see. Hank will try both of these methods in other than new products. We told Hank and Jack of the growing interest and sales totals of RG-244 and th were quite interested, knowing the savings involved. . smo nc - ^ i.cr.roc k. 90**1 5pring Street Redwood City, Ca I i L;. In+erviewed: September 20, 1971 E, M. Barretine . Recently a folio-.' up call vas made on 2r. Barrentlne regarding RG 244. He Eivisad teat the Oxnard plant vas still not operating as they had expected it would because of larger parts for dispersing equipment that have still not been'received from General Electric. ' Vhen these parts, are received and they are in production, RG 244 will be given a trial run at this plant. Mr. Barrentine stated that his tests harve shown the pre-vet has been better using RG 244 when coopered with the Pyrogeiii.es. As they should definitely be using on* material, it would now be advisable for sooeone froa our San Marino office to call on Mr. Cordon Johnson at DianonJ-Shamrock's Oxnard plant. MobiI Trim 'SisJ'JLL' Torn Fletcher September 14, 1971 Interviewed: Harry Wilson Harry can't use short fibres in his adhesive tape. The SG-144 is one he can possibly use and will evaluate. He will phone his results to me and also requests freight rates from King City. Hi Call made with R. Larkin and R. Byrne, ''Jeff Rittenberg PPG Industries Torre nee, Ca1 i f . . September 14, 1971 interviewed: Curt Cooper J. Frank Curt, the plant engineer, needs all the info he can get regarding the various respiratory aids, ventilation and dust arrestors which are necessary when using Asbestos or Silicas. Their production area has no adequate ventilation or draft. Bob Byrne will send to him compiled data on all these facts. Curt has a complete engineering job to do for thU plant. We discussed Asbestoeis ask and Silicosis and how they were not related to Cancer in proper usage and that RG-244 was Chrysotile and not Chrysolite Asbestos. John Frank discussed viscosities and asked how stable our RG-244 would keep the Droduct and hessaa he wa6 assured that it would ho much better than Cabosil. Other advantages over Silicas and its superior wetting and less dust pollution were also pointed out to then. PPG needs the go-ahead from their Springdale Bab to go ahead with producing Calidria Polyesters in this plant. CaIitornI a September 13, 1971 Interviewed: George Hicks Dan Kennedy `George just returned to work today and plans to push the RG-244 and will shortly make a large batch using the Calidria. Their Bay area plant will also be jstartlng with his formulations. (We also discussed the toxilogical aspects and the normal safety measures to be used in handling the Calidria. We are to inform RCI on U.C. '* compiled findings when released soon. Call made with R. Larkin and Byrne, ' jeff Rittenberg 3 iIma r Chemical Hawthorne, Calif. Interviewed: September 14, 1971 L. Bedeghian 0. Zaske Leon and Oscar discussed the various viscosities as reported by U.C. in the letter of Sept. 2, It was learned that these wo**e-results were low because no additive (Glycol) was added to the sample while it is in Siimar`8 comparable Cobosil resin. Oscar wants a less settling out thixotrope and is conducting tests now using xs various additives in his Cabosil resins. He believes his results are quite favorable to date. \. We told them feat sales proved the success of others in Calidria Polyester resins and they should also be able to achieve this. ; Oscar asked U.C. for a gallon of Sonolated resin with R.G-244 in it so Leon can put it in a stand tube and check it for settling over a period of time. Bob Byrne will have thiB done and send the sample to Oscar after he returns to the East. Both were also told of the various working advantages as to less dusting easier mixing better suspension, etc. when using Calidria intead of Asbestos Call made with B. Byrne and B. Larkin. i
