450 (Johns-Manville)

450 was a Johns-Manville insulating cement; J-M's sworn answers in two lawsuits, given in 1969 and 1970, list it as "#450 INSULATING CEMENT."1,2,3 An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives it as made from 1930 to 1972.4

A 1990 EPA notice that published what Manville reported gives figures only for a whole group of "Asbestos-Binder" cements, 450 among them, alongside Superex and 85% Magnesia.5 For that group it gives production years of 1930 to 1973 and says the cements contained 10 to 100% asbestos, with 0 to 30% each of diatomaceous earth, clay, portland cement and mineral wool.5 It describes the group as off-white to grey in color, packaged in cans or pails.5

J-M swore in both lawsuits that on or about December 15, 1964, it began putting a precautionary label on #450 Insulating Cement.1,2,3 The label began "CAUTION THIS PRODUCT CONTAINS ASBESTOS FIBER," and told users who could not control the dust to wear respirators approved by the U.S. Bureau of Mines.1,2
