M-53 TRIM AND TRELLIS GRBBH3 / WT s csy^iai This report covers the work done in connection with In vestigation WT-55 to utilize Beckosol P-296 (SO-3401-70$ solids K&-34Q2-6Q$ solids) a 64$ soya oil alkyd resin manufactured by Reicbhold Chemicals In., in Trim & Trellis Lt. and Dk. Greens. Details of Development P-296 was blended with RC-103 and RC-204 to shorten the oil, however, a product made with a straight substitution for RQ141 seemed satisfactory. This product retained a slight top tack, but had better through dry after overnight drying and was slightly lower in initial gloss than 87-102 and 87-103. It was necessary to remove all 348-18323 Ammonium Stearate to overcome rapid gela tion in the can. Flooding with laboratory batches containing 3$ VM-779O on the pigment was negligible, however, Philadelphia factory pro duction varied considerably, some batches flooding to an object ionable degree. Before this problem could be overcome in the fac tory, it was decided by Wilmington that P-296 would be used in whites because of the better color retention inherent in soya oil resins and accordingly both the Lt. and Dk. Green reverted to man ufacture with RC-141. Release letter #922 was distributed to cover the two greens under the codes 87-674 Dk. Green and 87-675 Lt. Green. Ma terials have been exposed in Series 8989, Series 9008, and Series Package stability has been satisfactory now for a period of five months. Stability study will continue and durability in formation from present exposures will be collected. Ho further work is contemplated.
