Y. Problem - Our Mr. W. Gettel, Mr. I. F. Weibel and this writer travelled to the Rochester area in order to deliver five cans of Asbestos Free Ready Mix to the Rochester Acoustical Co. for trial of working properties. You will all remember that this customer used some of the first Asbestos Free Ready Mix made at the Akron plant on January 8, 1976. The report covering this initial use of the present formulation is dated January 12, 1976. Results - Upon arrival at the job site, we met with Mr. Rudy Kumpf, job superintendent for Rochester Acoustical. This was the same gentleman we talked to on the first trial. We told Mr. Kumpf that we had adjusted the material we were delivering as he had suggested during the first trial. That is, we lowered the viscosity of the material and adjusted raw material content so as to deliver more "slip". Mr. Kumpf opened one of the fresh cans and applied the material straight from the can to several "flats" in one of the rooms he was finishing. He announced that the Ready Mix was much improved. He told us that the viscosity was just right for a taping operation and was much, much easier to work than the first Ready Mix he had used, even after the viscosity had been adjusted to his liking We talked about taping and finishing problems at some length, and then, Mr. Kurjf told us that he was not really satisfied with the bonds he was getting on the job in question. He mentioned that his tape did not appear to adhere as well as it should. Mr. Kumpf then proceeded to strip some tape from a bedded joint. It appeared that this was done very easily and fiber tear only occured on the very edge of the tape. When asked, Mr. Kumpf told us that he was using Gold Bond and USG"s Perf-o-tape. Samples of both these tapes were collected by our Mr. Gettel for further examination. We informed Mr. Kumpf that we had no sign of bond failure when the Asbestos Free Ready Mix was tested prior to delivery at the Harley School. The material in question here would be Asbestos Free coded c'0* 12095A5.6 or 7. Examination of the taDe at the iob site revealed that niether SGP 0008507 -2 brand was properly skived ar roughened across the entire width of the tape as they should be. Mr. Kumpf told us that he was not really having any trouble and the tape was adhering well enough to coat over. However, it is this writer's opinion that this matter should be looked into in case a problem arises later on. Again, when asked, Mr. Kumpf told us that he noted this lack of bond some time ago, and that several other tapers that he knows have reported the same problem on other jobs. As stated earlier, our Mr. Gettel collected samples of the tap'* in question and we are sure that he will check these and notify all concerned of the results. For C. W. Lehnert, A. J. Petraline, I. F. Weibel and File Copies onlyt The Asbestos Free R/M delivered to the Harley School on 2/17 was material coded 02056A2. Viscosity as manufactured was 405. Viscosity was checked at Akron on 2/16/76 and found to be 580. We understand that our Mr. Gettel checked the sample sent him and he reported that he found the material to be 575 on 2/16/76. This Ready Mix also contained Tamol 731. SGP 0008508
