Their report dated 1/25/46 written by Mr. Dgstad and left with J' If. Ilift covers the work done. Tests sere planned to determine where suoh a varnish would fit In comparison pentaerythritol being studied. A varnish was made up on A-D-M1 s suggested formula and was tried with two pigmentations In addition, 75-5 Oil was tried alone and 75-5 Oil acids have been made up into pentaerythritol and glycerine alkyds, The paint using the A-D-M varnish formulas dry hard and well. In thin films they were slightly better even than the pentSr erythrltol control. This was not at all true of thicker films. They dry through somewhat faster than the prewar controls. These are low gallon varnishes actually being about 25 tllon oil length. In view of, this and the comparatively lesser rough drying potential than the pentaerythritols, no further work is planned to establish them in a high quality line. However, floor enamels are a suitable place to use up surplus 75-5 Oil at quality equal to interior floor enamel and exterior porch enamel. The varnish formula with DuPont pigmentation seems the likely choice of the group with "45 Process" grind to obtain good dispersion and overcome flooding and settling. The alkyds of 75-5 Oil acids have exceptionally fast dn> but are softer than our present experimental so^a-PE floor enamel Details: vehicle. When modified;, the 75-5 Oil dries tack-free in a thin film but skin dries and wrinkles badly in thick films. Its tackfree time is about 5 hours. The Pentalyn M varnishes recommended by A-D-M dry to tackfree films in 8 hours. Thick films (2 mils) are considerably softer N 30718 than finger hardness and would not he Quite suitable for traffic at 8 hours. They are equal to or better than the prewar control for hard drying, however. Alkyda mde from the 75-5 Oil acids have remarkable tackfree tine. The glycerine alkyd dries in 4-1/2 hours and the pentaerythritil alkyd Is dry in 2 hours, However, they do not have hardening properties equal to the soya bean oil sold, pentfeerythritol alkyd modified with 801 Amberol. nDTJX,flX" doping solution, VC-1000, contrary to its effect on soya bean oil acid pentaerythnltol sloes the dry of 75-5 Oil acid pentaerythrltol alkyd from 2 to 8 hours. All of the 75-5 variations impart high gloss. Only the straight 75-5 Oil wrinkles in a heavy film. They settle badly and have a tendency to flatten. It is claimed by A-D-I4 that .25^ of soya lecithin will overcome the settling. The flooding and settl ing might be overcome by a "45 Process" grind* A strip comparing the 75-5 Oil varnish with ear-time and prewar control has been painted in the second flomr hallway. Drying results and 17 hour hardness readings are listed In the attached table. $050, Enamels will be exposed in the supplement to Series Ho.
