Panelag Refractory Cement by Quigley Company

Product Description

Panelag Refractory Cement was a high-temperature bonding and patching compound manufactured by the Quigley Company and sold primarily to industrial facilities requiring durable heat-resistant construction and repair materials. Produced from approximately 1940 through 1974, Panelag was formulated to withstand the extreme thermal conditions found in furnaces, boilers, kilns, and industrial heating systems. The product was marketed to steel mills, glass manufacturing plants, power generation facilities, foundries, and other heavy industries where refractory linings were essential to continuous operations.

Quigley Company, headquartered in New York, was one of the prominent manufacturers of refractory and insulating products in the United States throughout the mid-twentieth century. The company supplied a broad line of heat-resistant materials under various trade names, and Panelag Refractory Cement was among its recognized product offerings in industrial markets. Panelag was applied as a castable or trowelable cement used to set refractory brick, seal joints and cracks in furnace linings, and patch deteriorating refractory surfaces during both new construction and ongoing maintenance operations. Its workability and heat-resistant properties made it a common choice for tradespeople performing refractory work across multiple industrial settings.

Production of Panelag Refractory Cement ceased in 1974, corresponding broadly with the period during which scientific and regulatory attention to asbestos hazards in industrial products intensified.


Asbestos Content

Panelag Refractory Cement contained chrysotile asbestos incorporated into its refractory cement binder. Chrysotile, also known as white asbestos, is a serpentine-form mineral fiber that was widely used in refractory and insulating products throughout the mid-twentieth century because of its resistance to heat, its binding properties when mixed into cement matrices, and its relatively low cost and availability.

In refractory cement formulations such as Panelag, chrysotile fibers served multiple functions within the binder system. The fibers reinforced the cement matrix, improved resistance to thermal cracking, and helped maintain structural integrity under repeated heating and cooling cycles. These properties made asbestos an attractive additive for product engineers seeking to enhance the durability and performance of refractory cements in demanding industrial environments.

The use of chrysotile asbestos in the binder of Panelag meant that the product could release respirable asbestos fibers at multiple points in its lifecycle — during dry mixing, during application, during finishing and troweling, and during subsequent maintenance or demolition activities when cured refractory cement was disturbed or broken apart. The health hazards associated with chrysotile asbestos inhalation, including mesothelioma, asbestosis, and asbestos-related lung cancer, are well-documented in the scientific and regulatory literature, including standards promulgated under the Asbestos Hazard Emergency Response Act (AHERA) and OSHA’s asbestos exposure regulations found at 29 C.F.R. § 1910.1001 and § 1926.1101.


How Workers Were Exposed

Several trades encountered significant asbestos exposure through direct and indirect contact with Panelag Refractory Cement during the product’s decades of production and use.

Refractory workers faced the most direct and sustained exposures. These tradespeople applied Panelag as part of new furnace construction and performed ongoing maintenance and repair of refractory installations. Mixing dry Panelag cement, troweling it into place, and grinding or chipping cured material during repair cycles all generated airborne asbestos fiber concentrations. Refractory workers frequently operated in enclosed or semi-enclosed spaces such as furnace interiors, where ventilation was limited and fiber concentrations could accumulate.

Steel mill maintenance workers encountered Panelag in the repair and upkeep of blast furnaces, coke ovens, ladles, and other high-temperature equipment central to steelmaking. Maintenance operations that required breaking into existing refractory linings or cutting away damaged cement released fibers from previously installed Panelag material. The pace and frequency of maintenance work in steel production environments meant that these workers experienced repeated exposure over the course of long careers.

Glass plant workers were exposed to Panelag during the construction and maintenance of glass melting furnaces and annealing lehrs, where refractory cements were essential to managing the extreme and sustained temperatures required for glass production. Kiln repair and furnace rebuilding activities were periodic but intensive, and workers performing this work often operated without respiratory protection adequate to address asbestos fiber hazards.

Boilermakers applied and disturbed refractory cements including Panelag in the construction, repair, and overhaul of industrial boilers and pressure vessels. Boilermaker work often took place in confined spaces during scheduled maintenance outages, creating conditions under which asbestos fiber levels could reach hazardous concentrations in the breathing zone.

Across all of these trades, the hazard was compounded by the general absence of engineering controls, respiratory protection, and worker hazard communication during the primary decades of Panelag’s use. Regulatory requirements mandating exposure limits and protective measures for asbestos did not become broadly enforceable until the 1970s, after the period during which most occupational exposure to Panelag occurred.


The Quigley Company filed for bankruptcy protection, in part due to the volume of asbestos-related personal injury claims arising from its product line. As part of that bankruptcy proceeding, the Quigley Company Asbestos PI Trust was established to provide compensation to individuals who were injured by exposure to Quigley Company asbestos-containing products, including Panelag Refractory Cement.

Trust Name: Quigley Company Asbestos PI Trust

Product and Manufacturer Eligibility: Claimants with documented exposure to Panelag Refractory Cement manufactured by the Quigley Company are eligible to file claims with the Quigley Company Asbestos PI Trust. The trust’s claims submission process requires documentation establishing product identification, occupational exposure history, and a qualifying asbestos-related diagnosis.

Typical Claim Categories: The trust processes claims across the standard categories recognized in asbestos personal injury litigation and trust fund administration, including:

  • Mesothelioma — the most severely compensated category, recognized as a signature asbestos-caused malignancy
  • Lung cancer — compensable when supported by evidence of significant asbestos exposure and qualifying occupational history
  • Asbestosis — a progressive fibrotic lung disease caused by prolonged asbestos inhalation
  • Other asbestos-related conditions — including pleural disease and other nonmalignant respiratory impairments meeting trust eligibility criteria

Workers in the refractory, steel, glass, and boilermaking industries who handled or worked near Panelag Refractory Cement during the product’s production years of 1940 through 1974 may have qualifying exposure histories. Family members of occupationally exposed workers may also have secondary exposure claims in some circumstances.

Individuals who believe they were exposed to Panelag Refractory Cement or other Quigley Company products and who have received an asbestos-related diagnosis are encouraged to consult with an asbestos attorney experienced in trust fund claims. An attorney can assess exposure documentation, medical records, and work history to determine eligibility and assist with the filing process for the Quigley Company Asbestos PI Trust.
