Eagle-Picher Insulating and Finishing Cements
Understand the difference between a family of products and a named formulation.
A product family
Historical sources identify insulating and finishing cements associated with Eagle-Picher. Trade names reported in secondary references include 43, One-Cote and Hylo; precise formulations and date ranges should be checked against manufacturer or government records before being treated as established.
The work sequence
Workers might remember dry material being carried to the job, mixed with water, applied to thermal insulation, smoothed and later removed during maintenance. Product type, time and equipment matter.
Beyond the cement
Pipe covering, block insulation and weatherproofing names also appear in later industry histories. Do not assume that every similarly named product contained asbestos or was made by the same company at every date.
Original historical records
Follow the underlying federal notices, court decisions and bankruptcy history.
Start with what you remember
A product name, job, coworker, photograph or date can help reconstruct the history.
