One-Cote insulating and finishing cement: dates, appearance and uses
A federal manufacturer identification provides unusually precise product chronology, ingredients and physical characteristics.
The dates matter
A federal manufacturer-identification notice reports that Eagle-Picher produced One-Cote from 1960 through August 1971. It specifically states that One-Cote did not contain asbestos before April 1960 or after August 1971. This is a product-specific chronology, not a statement about every similarly named finishing cement.
Appearance and handling
The notice describes a hydraulic-setting insulating and finishing cement drying to a smooth white or off-white hard finish. Dark mineral-wool nodules, generally one-eighth to three-eighths inch across, were dispersed through the binder. These descriptions may help distinguish a recalled product from other insulating cements.
Formulation changed over time
The federal entry gives chrysotile asbestos content as 5–6% from April 1960 through 1967 and 2–5% from 1968 through August 1971. Its other components include mineral wool, Portland cement, bentonite clay and diatomaceous earth, with changing percentages.
Names and job tasks
The 1959 Eagle-Picher manufacturing specification identifies NARCO Unicote as regular Eagle-Picher One-Cote; a later federal record provides the asbestos-specific chronology. In a published appellate opinion, a pipefitter recalled One-Cote used to finish joints in the late 1960s. The court did not find that recollection sufficient to connect the product to the particular plaintiffs.
