H. B. Rhodes to J. E. Walsh on Using Calidria Asbestos to Partially Replace Cellulosic Thickener in Paints (1974)

Internal letter from H. B. Rhodes to J. E. Walsh reporting available information on replacing part of the cellulosic thickener in paints with Calidria asbestos. It estimates about 25% replacement at roughly two pounds of asbestos per pound of cellulosic removed, suggests a mixing sequence, and recommends a cautious, limited field trial. Attached are a 3/26/74 note with viscosity discussion, a Calidria latex paint product sheet, and viscosity tables and graphs.
