Product Description

Karnak Corporation (Clark, New Jersey) manufactured through the asbestos era a major U.S. line of asphalt-based roofing mastics, plastic cements, fibered aluminum coatings, flashing cements, wet-dry roof patch, and related roofing-trade adhesives and sealants. Karnak products were sold through roofing-supply distributors nationally and were standard inventory for commercial flat-roof contractors, residential roofers, and building-maintenance departments through the 1980s.

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Karnak’s asbestos-fibered roofing mastics, plastic cement, flashing cement, and fibered aluminum coating contained chrysotile asbestos throughout the documented production era and that workers who applied, troweled, brushed, or tore off Karnak products released respirable asbestos fibers.

Karnak Corporation has been named as a Manufacturer Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.
