All quality tests have been satisfactory. However, we find that the Asbestos-free is requiring more mixing time than the Asbestos formula, and subsequently,our production rate has dropped about ten batches a day(five pr shift). The Asbeatoth-equirea a entirely different muting cycle. Water,avace, Nalco and Her M added t0 tho *ixer' 7h0 is mixed until it is lump-free. At this time,Acrysolia. liquid thiekner) is added to the- blended filler, and mixed until it reaches the pumping viscosity of h2 0 i*20pts. Retain samples indicate a viscosity rise of ISOpts -l60pta after 2k hrs We have experienced soma problems regarding a humid bond.. Bond tests in dicate about *0* fiber tear at 12* moisture{readings were taken with a. model DC-10 moisture register). However,at this level(12) a 100% tear . is noted with cur old Asbestos formula* 12ven at a ?Ltrvei(considered dry) the 'msbestos-free does not yield as strong a bond as the Asbestos formula Subsequently, we have raised our-SLvace loading to 1#U(formula usage) iUZlbs pr batch to insure a satisfactory bond. We have yet to hear any field reports concerning ita market acceptance. At such time any information is received you willbe advised. cc:HrA.
