Eagle-Picher Product Recognition: Super 66 and One-Cote
Color, texture, finish and work process can help distinguish two historically documented insulating cements.
Super 66 / Eagle 66
A federal manufacturer identification record describes Super 66, formerly Eagle 66, as an insulating cement made from 1930 to August 1971. Once dry, it had a grayish-white appearance with dark mineral-wool nodules distributed through the binder. The record documents formulation changes over time, including changes in the proportion of chrysotile asbestos.
One-Cote
The same federal record identifies One-Cote insulating and finishing cement from 1960 to August 1971. It describes a smooth white-to-off-white hard finish and a different formulation from Super 66. A remembered finishing coat may therefore point to a different product than the underlying insulation cement.
Reconstruct the task
Was dry material mixed in a pail or pan? Was it troweled around pipe elbows or used to finish joints? Was the material still in bags? Were repairs occurring during a shutdown? The work sequence, nearby equipment, label and year can be more useful than a color remembered decades later.
