BURNETT, MANAGER LAKES AND LEATHER SECTIONS DYES AND CHEMICALS DIVISION "LITH030L" FAST VIOLET 4RNL PASTE LOT 108 - 40 POUNDS FOR STANDARD Forty pounds of subject color has been placed in Technical Laboratory Annex to replace Lot 207. Lot 208 is to be used as the Qrchem testing standard as it represents material Which the plant has been producing on a regular basis and acceptable to the Pigments Department. The Pigments Department will continue to use Lot 83 plant manufactured toner as their standard for acceptance. Wille Lot 108 is 5.0# strong versus Lot 107 it is only 2-1/2# stronger than Lot 83. The Lake Laboratory does not adjust strength based upon dye test results. Due to the lengthy test {3 days) all lots are adjusted for solids by the plant and packed out. A comparison of these two lots in lacquer, after converting to resinated toners, shows the following: Parts Sample Shade 100 Lot 107 Control 95 Lot 108 4B1 AWBsmch A. W. Bilancioni
