Zonolite Company / W. R. Grace & Co. plant at Easthampton, Massachusetts

In sworn answers in a 1987 lawsuit, W. R. Grace & Co. listed Easthampton, Massachusetts, with the dates "1964-1973," among the plants for Zonolite Mono-Kote MK-3, saying the product "was manufactured at some or all of the plants listed below."¹ The answers do not say which company ran the plant: they say the product was made by Zonolite Company from 1959 to 1963 and by Grace "from 1963 until 1973."¹ Grace described Mono-Kote MK-3 as a "Light beige cementitious material" used for fireproofing, containing short fiber chrysotile asbestos, about 13.23 percent by weight in one grade and 12.18 in another; those figures describe the product in general, not Easthampton's output in particular.¹
