Permiseal was an insulating sealer and weather-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 "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 ingredients, with the drum sizes typed as 5, 30 and 35 gallons.2,3
An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, lists Permiseal as a coating under Combustion Engineering, made from 1964 to 1975, with 3 in the column read as percent asbestos.4
