Super 66 and Eagle 66 Insulating Cement
A product-name change that may help connect memories across decades.
Names and dates
The federal product-identification notice describes Super 66 asbestos-containing insulating cement, formerly called Eagle 66, and dates its manufacture from 1930 to August 1971.
Physical identifiers in a federal notice
The 1990 federal manufacturer entry describes Super 66 as drying to a grayish-white color with dark mineral-wool nodules, generally one-quarter to one-half inch across, dispersed through the binder. It also records formulation changes over time. These are unusually specific clues when a person recalls the texture or appearance of material rather than the label.
What workers may remember
Insulators may remember a sack or drum, dry powder, a mixing station, a trowel, or cement applied to bends, valves, fittings and irregular insulation surfaces. These are prompts for recollection, not claims that a specific product was used at any particular jobsite.
What to verify
Look for a purchase order, packaging photograph, specification, invoice, foreman name or job period. A generic recollection of cement does not identify Super 66.
