Product Description
Johnson March Corporation supplied refractory crown block, back-up insulation, and seal cements for glass-melting tanks used in container, flat-glass, and specialty glass plants. According to publicly filed asbestos litigation records, Johnson March crown block back-up insulation and companion seal cements allegedly contained asbestos to withstand the extreme temperatures and long campaign lives of glass tank crowns. During cold-repair and hot-repair rebuilds, workers allegedly cut and set the crown block, packed asbestos seal cements around burner ports and tuck-stones, and later demolished the crown at end-of-campaign, allegedly generating airborne fibers during each phase.
