Ace-Tite Cement (Cominco): Product Reference

Product Description

Ace-Tite Cement, also identified in industrial records under the alternate product name Cominco, was a cement-based construction and insulation compound manufactured by United States Mineral Products Company. The product belonged to a broad family of mineral-based cements that were widely used in industrial and commercial construction applications throughout much of the twentieth century, particularly in settings requiring thermal insulation, fireproofing, or pipe coverage.

United States Mineral Products Company, headquartered in Stanhope, New Jersey, produced a range of asbestos-containing building products under various trade names during this period. Ace-Tite Cement was among the company’s offerings marketed to industrial contractors and construction trades as a versatile material suited for both pipe insulation and spray-applied fireproofing applications. Products under this general category were commonly specified in power plants, refineries, shipyards, chemical processing facilities, and large commercial building projects where fire resistance and thermal management were engineering priorities.

The dual-category nature of Ace-Tite Cement — covering both pipe insulation and spray fireproofing uses — meant that it appeared in a wide variety of industrial environments and was applied by multiple trades working at the same job sites, often simultaneously or in close sequence.

Asbestos Content

Cement-based insulation and fireproofing products manufactured by United States Mineral Products Company during the mid-twentieth century are documented in litigation records as having contained asbestos mineral fibers. Asbestos was incorporated into these types of cement products for its well-established functional properties: it enhanced tensile strength within the cement matrix, improved resistance to high temperatures, and contributed to the material’s overall fire-retardant performance.

In products classified as pipe insulation cements, asbestos fibers — most commonly chrysotile, and in some formulations amphibole varieties such as amosite — were blended with binding agents and other mineral materials to create a workable paste or trowelable compound. When applied to pipes, boilers, and thermal equipment, the asbestos-reinforced cement formed an insulating jacket intended to reduce heat loss and protect surrounding structures.

In spray fireproofing applications, asbestos-containing materials were mixed into a slurry and pneumatically applied to structural steel beams, columns, and ceiling decking. This application method was particularly associated with elevated fiber release, as the spraying process and subsequent disturbance of dried material could generate significant quantities of airborne asbestos particulate.

Litigation records document that Ace-Tite Cement and comparable United States Mineral Products Company offerings contained asbestos as a constituent material during their production and distribution. The specific fiber percentages varied by product formulation and production period, consistent with industry-wide practices of the era.

How Workers Were Exposed

Industrial workers in a broad range of occupations encountered Ace-Tite Cement and similar asbestos-containing cement products through both direct application and secondary or bystander exposure in shared work environments.

Application and Installation Workers: Workers who mixed, troweled, or spray-applied Ace-Tite Cement were in direct and sustained contact with the product during active use. Mixing dry cement compounds — or combining them with water to create a workable paste — could release substantial quantities of airborne asbestos fibers, particularly in enclosed or poorly ventilated spaces. Trowel application to pipe surfaces and mechanical spray application to structural steel both required extended hands-on work with the material at close range.

Pipe Insulation Trades: Insulators, pipe coverers, and related trades applied cement-based products directly to steam lines, process piping, and mechanical equipment throughout industrial facilities. These workers handled asbestos-containing insulation cements routinely and over extended periods, constituting a population with elevated historical exposure potential.

Fireproofing and Construction Trades: Workers involved in spray-applied fireproofing operations — and those working nearby when such operations were underway — were exposed to airborne asbestos fibers generated during the spraying process. After application, dried fireproofing material remained susceptible to disturbance during subsequent construction phases, creating ongoing exposure potential for ironworkers, electricians, plumbers, duct installers, and other trades working around or above treated structural members.

Maintenance and Repair Workers: Facilities maintenance personnel who disturbed, repaired, or removed existing pipe insulation or fireproofing material — often decades after original installation — faced significant secondary exposure risks. Cutting, chipping, or scraping aged asbestos cement released fibers that had been bound within the hardened material since original application.

General Industrial Workers: Plaintiffs alleged in litigation proceedings that general industrial workers in plants, refineries, and manufacturing facilities were exposed to asbestos fibers released by Ace-Tite Cement and similar products as a result of proximity to application areas, maintenance activities, and the general degradation of installed materials over time. Workers did not need to directly handle the product to sustain exposure in environments where it was present.

Regulatory frameworks including OSHA asbestos standards and AHERA documentation have established that asbestos-containing cements of this type are capable of releasing respirable fibers under conditions of normal use, application, and disturbance. Diseases associated with occupational asbestos exposure — including mesothelioma, lung cancer, asbestosis, and related conditions — can develop with latency periods of twenty years or longer following initial exposure.

Documented Trust Fund / Legal Options

Ace-Tite Cement manufactured by United States Mineral Products Company falls within Tier 2 of asbestos litigation classification. No dedicated asbestos bankruptcy trust fund has been identified that specifically covers claims arising from United States Mineral Products Company liability for this product line. Individuals seeking compensation for asbestos-related illness connected to Ace-Tite Cement or Cominco products are advised to pursue relief through the civil litigation system.

Litigation records document that plaintiffs have brought claims against manufacturers and distributors of asbestos-containing pipe insulation and spray fireproofing products, including those in the United States Mineral Products Company product family, alleging that these companies knew or should have known of the health hazards posed by asbestos-containing materials and failed to adequately warn workers of those risks.

Plaintiffs alleged in filed cases that manufacturers of asbestos-containing cements, including spray fireproofing and pipe insulation compounds, were negligent in their product design, failure to warn, and marketing of hazardous materials for use in occupied industrial environments. These claims have been brought under theories of negligence, strict product liability, and failure to warn in jurisdictions across the United States.

Individuals who may have legal claims include:

• Industrial workers diagnosed with mesothelioma, asbestosis, lung cancer, or other asbestos-related diseases who worked with or around Ace-Tite Cement or Cominco products
• Workers employed at power plants, refineries, chemical facilities, shipyards, or large commercial construction projects where United States Mineral Products Company materials were specified or used
• Family members of deceased workers eligible to bring wrongful death claims

Because asbestos litigation involving non-trust defendants requires individual case investigation, affected individuals and their families are encouraged to consult with an attorney experienced in asbestos personal injury law. Statutes of limitations apply and vary by state; claims are generally measured from the date of diagnosis or discovery of illness. Preserving records of employment history, job sites, and product exposure is important to supporting any claim.
