KAI5^ GYPSUM COMPANY ^C. INTER-OFFICE MEMORANDUM JTo C. E. Caprye - Seattle R. L. Muhr - Antioch Date April 8, 1975 Copies to G. B. Kirk E. H. Schaper From at / --> T. V. Smith Antioch E & D Subject PREMIX DUAL PURPOSE NON-ASBESTOS Work Order #696-314 We recommend producing one batch of Non-Asbestos Premix Dual Purpose on the attached test batch Bulletin. We have found the use of Cellosize QP4400H to be critical to this mater ial in obtaining proper water levels and workability. Min-U-Gel FG replaces Attagel 40 at a lower cost. Since the Min-U-Gel FG is not stocked on the west coast, Attagel 40 can be used in these test batches. Please send us a 5 lb. sample from the batch for our full product speci fication testing prior to release to Sales for the field evaluations.
