One-Cote Insulating Cement (Eagle-Picher)

One-Cote Insulating Cement was a refractory product manufactured by Eagle-Picher Industries during the 1960s and into the early 1970s. Litigation records document that the product contained chrysotile asbestos as a functional component of its formulation. Workers who applied, mixed, or handled this cement in industrial settings were potentially exposed to airborne asbestos fibers at levels that plaintiffs alleged were harmful and inadequately disclosed by the manufacturer.

Product Description

One-Cote Insulating Cement was a single-application refractory cement designed for use in high-temperature industrial environments. Products in this category were engineered to provide thermal insulation and fire resistance on surfaces such as boilers, kilns, furnaces, ovens, and industrial piping systems. The “one-coat” designation reflected a product intended to be applied in a single layer rather than requiring multiple coats or additional finishing materials, streamlining the application process for industrial maintenance and construction crews.

Eagle-Picher Industries, headquartered in Cincinnati, Ohio, was a diversified manufacturer with extensive product lines spanning industrial minerals, construction materials, and specialty chemicals. The company operated as a major supplier to heavy industry throughout the mid-twentieth century. One-Cote Insulating Cement was produced during the period spanning approximately 1960 to 1971, years during which asbestos-containing refractory and insulating products were in widespread industrial use across the United States.

Refractory cements like One-Cote were common fixtures in facilities including steel mills, power generation plants, refineries, paper mills, chemical plants, and shipyards—essentially any operation involving sustained high-heat industrial processes. The product competed in a market where asbestos-bearing formulations were considered standard practice, and Eagle-Picher positioned it as a practical solution for insulating and protecting heat-exposed industrial infrastructure.

Asbestos Content

Litigation records document that One-Cote Insulating Cement contained chrysotile asbestos as a constituent of its formulated composition. Chrysotile, also known as white asbestos, is the most commercially prevalent form of asbestos and belongs to the serpentine mineral group. Despite its comparatively curled fiber structure relative to amphibole varieties, chrysotile has been classified as a known human carcinogen by the International Agency for Research on Cancer (IARC) and is regulated as a hazardous substance under federal frameworks including OSHA’s asbestos standards (29 CFR 1910.1001 and 29 CFR 1926.1101) and the Asbestos Hazard Emergency Response Act (AHERA).

In refractory cement applications, chrysotile asbestos served several functional purposes. Its heat resistance helped stabilize the cement matrix at elevated operating temperatures. Its fibrous structure contributed tensile reinforcement to the hardened material, reducing cracking under thermal cycling. These properties made asbestos a commercially attractive additive for manufacturers of insulating cements during this period, even as evidence of its health hazards was accumulating in medical and industrial hygiene literature.

Plaintiffs in litigation have alleged that Eagle-Picher was aware of the hazardous nature of asbestos in its products during the years One-Cote was manufactured and sold, and that the company failed to provide adequate warnings to workers who would foreseeably encounter the product during its use and application.

How Workers Were Exposed

Industrial workers across a range of trades and facilities were potentially exposed to asbestos fibers released during the handling and application of One-Cote Insulating Cement. Litigation records document that exposure scenarios arose at multiple points in the product’s lifecycle, from initial mixing through application, drying, and any subsequent maintenance or removal work.

Mixing and preparation posed a significant exposure risk. Workers who combined powdered or semi-dried refractory cement with water or other components in preparation for application could disturb the dry material and release asbestos fibers into the surrounding air. Bags of refractory cement product, when opened and poured, could generate visible dust clouds in poorly ventilated workspaces.

Application by trowel, brush, or spray brought workers into direct, sustained proximity with the wet or dry cement material. Spray application in particular could aerosolize fine particles, including asbestos fibers, across broader areas and affect not only the applicator but nearby coworkers working in the same industrial environment.

Surface preparation and removal activities—including scraping away old or damaged insulating cement before applying fresh material—generated significant dust. When existing refractory cement dried and was disturbed by tools or routine industrial vibration, it could shed asbestos-containing particulate into ambient air.

Bystander exposure was also alleged in litigation. Workers in adjacent trades—pipefitters, boilermakers, electricians, millwrights, and general laborers—who worked in the same facilities where One-Cote was applied or disturbed could inhale fibers without ever directly handling the product themselves.

Plaintiffs alleged that during the years One-Cote was manufactured and distributed, industrial workers were not provided with adequate respiratory protection, and that warning labels on the product did not communicate the carcinogenic risks associated with asbestos inhalation. Mesothelioma, asbestosis, and asbestos-related lung cancer are among the diseases that have been alleged in litigation connected to occupational asbestos exposures during this era.

Documented Trust Fund / Legal Options

Eagle-Picher Industries filed for Chapter 11 bankruptcy protection in 1991, primarily as a result of the volume of asbestos-related personal injury and wrongful death claims brought against the company. As part of its reorganization under the federal bankruptcy process, the Eagle-Picher Industries Personal Injury Settlement Trust was established to resolve present and future asbestos liability claims.

However, litigation records and trust documentation confirm that One-Cote Insulating Cement is not among the products listed as eligible for claims through the Eagle-Picher Trust based on currently available product and exposure criteria. Individuals seeking compensation for diseases allegedly connected to this specific product are directed to pursue relief through direct civil litigation rather than the trust claim process.

Claimants and their legal representatives should be aware of the following when evaluating options:

• Statute of limitations for asbestos-related personal injury claims varies by state. The limitations period generally begins running from the date of diagnosis of an asbestos-related disease, not from the date of exposure.
• Documenting product identification is essential in direct litigation. Evidence that One-Cote Insulating Cement was present at a specific worksite, and that the claimant worked in proximity to it, forms the factual foundation of a claim. Co-worker testimony, employment records, union records, and facility purchase records have all been used in documented litigation to establish product identification.
• Diseases covered in asbestos litigation include mesothelioma, asbestosis, asbestos-related pleural disease, and lung cancer with documented asbestos exposure history.
• Multiple defendants may be named in asbestos litigation arising from a single exposure history, as workers at industrial facilities often encountered products from numerous manufacturers during their careers.

Individuals who believe they have been exposed to One-Cote Insulating Cement or other Eagle-Picher refractory products and who have received a diagnosis of an asbestos-related disease should consult an attorney experienced in asbestos personal injury litigation to evaluate their legal options and identify all potentially responsible parties.
