Mills - Res 3' CFARL ; i j' j [ I j I asked A1 Morgan to comment on the explosions subject company has encountered. His reply is as follows: "A search of the literature indicates no Aroclor interaction leading to the explosion but there is plenty of indi- cation for a reaction between PbC>2 or Zn02 and the benzothiazole. This pro bably sets up a complex mixture of peroxides and oxides which are shock sensitive. Recommend changing pro- . , cedure to roll milling or slow shear mixed in a chilled container. Also believe a new accelerator might be a research objective for Sealocrete." . A reply from Jim Dilhoefer may be more helpful in solving this problem. A replacement for Santocure MOR should logically come from him. I We would like to see his reply please. ds i (Ua-- N. W. Touchette DSW 588480 STLCOPCB4093816
