Coverkote was a GAF weatherproofing coating for insulated surfaces, "rather than an insulating cement," as the company put it.1 GAF's 1989 filing with the U.S. Environmental Protection Agency under the Asbestos Information Act, made for itself and The Ruberoid Co., describes it as a black plastic material designed particularly to protect the insulation on large tanks and vessels and on insulated equipment such as smoke breechings and ducts.1,2
The filing says Coverkote was a combination of emulsified asphalt and 25 to 28% chrysotile asbestos, and gives its temperature limit as 400 degrees F.1,2
