' (1) Maleic Modified Oils ' -* -----j The control for house tests in 1949 was #40 Outside White {301-864; containing 20$ Soya Oil replacing linseed oil and pigmented with Leaded Zinc Oxide. The test.paints were lead-free using either ADM Or Spencer Kellogg produced maleic treated soya oil. : The inspections of; seven house tests showed that neither Ardol (ADM) nor Drisoy (SK) causes any significant improvement, statis tical or practical, in dirt collection or film integrity over the control, actual inspections indicated equality between both' experimental paints mid controlo. .' . ' * . ' ' ' * '1950; To%m and Country White which utilises a blend of two viscosities of Ardol was.tested this year* Two control paints were used. Prewar #40 (301-756) and Chivo House Faint (302-785). After 2-1/2 years4..,exposure, T&O White.was statistically equal in cleanli ness, which included both dirt and mildew, but when graded separately N35474 V ** s fox mildew# the' TfeC White showed Improvement over the Chive House Paint,' This average difference of 30 + 1.1 halts peep^ed on w houses in Florida, Film integrity ms 1A *9 units better than Chlvo House Paint on..these same tiro houses, The remaining- houses have not shown hay. decided failure. . '; Town and Country White did not show any improvement over Prewar #40 and gave an average difference in dii?t collection or 0 i**0,21 units and- for film .integrity an average difference of 0.05 *23 units. Both paints collected dirt and mildew equally and film failure -. occurred equally on both, ' . . ,. ; 1951? Two house paints were tasted this year# a linseed maleia{P^30IU-^086) and a soya maleic (P-3D1-U-4084) with #4 Outside White (30:i>885) as the control paint. These paints were pigmented th same as .301*"88$# but at 30$ W instead of 33$.' The three finishes were on nine houses ranging in age from 12 tj$p IS months. ' " -. . !- The linseed maleic paint (P-30Xu*4086) was rated from 6 to 10 for'dirt collection# but the average difference-was 0*13 + O, 2$ units# .reflecting the equality of experimental and Control* In Florida they mildewed equally but' sufficient film failure had not occurred in order to give a real difference in durability* The soya maleic paint (.P-3X~W-4o84) showed practically the same degrees of failure for dirt collection and'film integrity giving average differences of 0,11 * 0,26 units'and 0*02 0.05 ' units' respectively. **' ^' (2) Soya >1B. Oil ' . . \ . : -t " . ' 1 . ' ,. r t . 1948% Three houses were active, fr$ th 1948 test series# with PrewsrPR) as control. The test paint consisted-of straight soya P, E, oil# which Contained no glycerol. The soya P.l* Paint was equal to the control In cleanliness on all houses# but did not. indicate improvement since th average difference was .07*0.3',' There was an average:dlff4ren.se of X.SK-S.S unite in film integrity# including moisture failure# in favor of Soya SVE* oil over Prewar #40i There was a real difference oh three out of four tests. On the fourth test failure was dw to. moisture with m difference between tests. This one determination reduced th probability below the .95$ level# but therd appears to be a real difference between these two paints in durability, 1949:Aaother Soya P.B. .Paint was tested using an improved' ' vehieleTco.lorwIs'e) with the same pigmentation. The average "difference found on 15 tests was 0*02*0*11 units in cleanliness# indicating equality of both paints* fen houses were graded for film integrity giving an average difference of 0.11*0,24 units* . Failure did not occur on all houses but where it diCoc.cur# both paints failed equally, (3) Oalcium Carbonate Extender . Calcium carbonate was tested In 1948 in both outside white and cream tint at- 50$ of extender concentration and the results b~ talned. showed no difference statisticaily in dirt collection or film DUP030003523 I Integrity compared with Prewar #40 and #733 Light Cream Tint. . the control paint was'28# Ft While* the experimental paint was 35# Ft. These results are based on three houses which were four and a half years:old. . . -. One house test of. the same age using all calcium carbonate as extender in cream tint showed a marked improvement in cleanliness (+2,7) compared with Prewar #753 Cream. ; ' (*> Low Lead Primer ' '. "! s . Two primers .-containing .half the usual amount of lead were tested on houses in. 1949 with house paint primer containing the . normal amount f lead pigment. The first low lead primer (P-347~K~l4?l4} was. made by reducing the lead pigment by 50# and replacing it with .' extender, while the second primer (P-347~R~4o 6<)55 was made by replacing all the lead with lead silicate, also know as "45x" pigment# ". M From 5 test houses inspected, evidence taken from four tests Indicates that both low lead printers are equal to house paint primer {347-817) in durability. The fifth house lacked control area, therefore, we could not evaluate the test properly. ` - (5) High Hiding.White ' ` . ' 1949.8 High Hiding White using 35#' soya oil replacing linseed oil was teaUcf on seven houses with two coats versus. 301-864 Outside Hhite as the control. Hie tests are now 3-1/2 years old and show cleanliness .equal to the control on all tests. On those tests which . involved mildew conditions, there were no differences,'. The dif ferences encountered in film integrity were such that they did not become noticeable statistically (0.24*1,0). ' The customary film failure which could be expected due to one coat white did not occur since two coats .were applied, ' .. ', 1950?4 similar high hiding O.W. (301-754) containing all linseed oil wlitested m 10 houses using cm coat versus two coats 301-885, These were barely 1 year old and therefore showed nothing in respect, to film Integrity., However, there were some small differences . (0,07 * 0,17 units) on the improvement side f cleanliness, "but not large enough to show statistically. . . (6) Alkyd Primer .1949? fin alkyd primer using straight 55# linseed oil alkyd as vehicle^at 35# P. V. was tested on three houses with house paint primer (347-81?) a control and five houses with (301-864) outside white seif-primed as control, in both experiments, the results did DUP030003524 4- 'ft not show any statistical difference* although .failure occurred on all houses in very nearly equil severityi ' Using, house paint primer as control* the results on three houses was, 03 * 1.12* while using selfprimed outside white as the control on five houses* .the difference was 0,026 0*25 units.
