V.'right DATE: SUBJECT: March *C, 1970 Asbestos We ere coning "down to the wire" on our Mono-Kote reformulation work, whose chief object is the elimination of asbestos from the product. At this point, our most promising formula utilices an org:nic fiber. - _ Tom EgEn""in preparation of pronotion cfthe_new'procucc, nas ----- *T to be concerned about the emphasis which nay be used on elinination of asbestos. Whether he calls Kcno-Kote "asbestos-free" L or case other adjective, he needs to be sure that it is in in' deed free of asbestos. With the elimination of asbestos fiber which ve have added in our blending plants, the remaining worry is the amount of asbestos that ray be present in expanded vermiculite. .I've advised _that_ we use _wet_separat ion* in both beneficiaticn_ Bills and that it is highly improbable that detectable levels of asbestos could remain on the ore concentrate. I also expect that whatever rainute quantities of asbestos remained on the ore, they would be eliminated by the actidhs of air separation and Stoner activity in our expanding plants.
