Duxseal (Johns-Manville)

Duxseal was one of Johns-Manville's plastic sealing compounds.1,2 It was already part of that line in April 1944, when Asbestos, the industry's trade journal, reported J-M's announcement of a new compound, Uniseal, and said that like J-M's other sealing compounds, Duxseal among them, Uniseal "contains a high percentage of asbestos."1 The magazine gave no figure for Duxseal itself.1

The sources give different years. An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives Duxseal as made from 1957 to 1981; 1981 was the list's own year, so the end date may mean it was still being made.2 A 1990 EPA notice that published what Manville reported gives 1957 to 1977, but as one date range for a group of nine putty-like sealing compounds that includes Duxseal.3
The 1990 notice gives only figures for the whole group of nine compounds: asbestos, 25 to 65%, with butane polymer, castor oil, chlorinated paraffin, calcium carbonate and other ingredients, packaged as pugs in fiberboard cartons.3

In September 1945, Asbestos reported that J-M's employee magazine had listed the products J-M supplied to the Manhattan Project, Duxseal among them.4 J-M's 1955 instructions for running the dust collectors in its own plants said imperfect seals in the washers "should be corrected by use of J-M Duxseal."5 A 1969 memo from J-M's Environmental Control Department proposed that Duxseal be among the products that would not carry a caution label.6
