Cross Reference: wilm. Trade 87 Lin# Trim & Shutter Enamels Punch Card Index MEMORANDUM REPORT NO, M-387 CC: J. D. Rode,Wilm. S. Graves, Lab, File October 9, 1951 OcU'St VM-7796 SOYA LECITHIN IN'87-872 .TRIM & SHUTTER MAROON This report will record observations on film properties of '87-872 Trim & Shutter Maroon when VM-7790 Soya Lecithin Solution is included in the formula. Addition of 3~4.VM-7790 on total formula os a letdown ingredient increases the TM-311 B sag reading from 20 to 25 mm. In this respect the VM-7790 acts as a dispersing agent rather than a flocculating agent. Addition of VM-7790 also retards drying speed approximately 2 hours. When an excess of v m-7790 is added to 87-872 (over h%) it-causes the film to crawl. > The formula for 87-872 has been revised to eliminate VM-7790, the flow having been retarded through use of H-200 aromatic solvent in place of mineral spirits.
