Kaiser Gypsum Company, Inc. plant at Santa Ana, California

Kaiser Gypsum Company had a plant in Santa Ana, California; what is known of it comes from the company's sworn answers to interrogatories in a 1992 Dallas County lawsuit, which list the products made there and their years.¹ The earliest dates in those answers are 1968: "K-Spray Ceiling Texture" decorative ceiling paint, "Cover-Tex Wall Texture" decorative texture paint and "Dual Purpose Premix Compound" for gypsum wallboard were each made at Santa Ana from 1968 to 1975.¹ "Radiant Heat Compound," for electric radiant home heating systems, was made there from 1968 to 1974.¹

Later lines followed, by the same answers: "Premix Topping Compound" (1970-75), "One Day Joint Compound-Powder" (1971-75), "Filler Compound" for radiant heating systems (1971-72) and "Radiant Heat Scrimless Surfacing Compound" (1972).¹ The answers say these were never sold in Texas.¹ Wallboard "Laminating Compound" made at Santa Ana, with no years given, was sold to Texas customers.¹

A different company's sworn answers also name the city: W. R. Grace's answers in a 1987 lawsuit list Santa Ana, California, for 1972-1973 as a place where its fireproofing Zonolite Mono-Kote MK-3 was made; they name the city, not a Kaiser Gypsum plant.² The same answers describe the product in general as containing short fiber chrysotile asbestos, "approximately 13.23 percent 7M" and 12.18 percent "7R" by weight.²
