Duriseal (Combustion Engineering)

Duriseal was an asphalt mastic coating sold by R & I Refractory and Insulation Corporation, a subsidiary of Combustion Engineering, Inc.^1,2 In sworn answers given in a lawsuit in February 1968, R & I and Combustion Engineering described it as "a blend of asphalt mastics, comprised of asphalt and asbestos fibers," obtained pre-packaged in drums of 5, 30 and 55 gallon capacity; the answers do not say who made it.¹ Combustion Engineering's answers in two later lawsuits, in December 1969 and March 1970, give the same description.^3,4

An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, lists Duriseal as a coating under Combustion Engineering, made from 1964 to 1981, with 3 in the column read as percent asbestos.² Because 1981 is the list's own year, that end date may mean it was still being made.²
