Special attention was paid to ITC'e quality control expo, sure tests on their nen-chalklng rutile T10* Titanese UK. Mora detailed discussion will appear later, loverer, tesu la allqrd automotive enanels show ehac by selecting the right panels one could prove anything. Actu ally, as many of the leu of UK showed slight superiority ever t-610 ssaples in fade and chalh resistance u there ware inferior leu, and generally UK was definitely superior U OB-6fcO. Share were exceptions to every one of these sutaaeau la isolated esses and one let of UK was poor, ft 610 shewed uniform performance at a good level la the few aaplea tested. Confirming TfC's earlier sutaaeau, U 90 shewed a high level of gloss and color retention, generally the hut of ell tbs rutila pigments in this series. Naturally the one peer let of UK is a matter of great concern. TfC's production daparenaat has been shown thus expo sures and are aware of the dangers of any lulty In central of quality. He would aaticipau that in future shipmeaU of UK there will be a narrower range in fade and chalk resistance. Zt should be noted that no numerically equal mUhtr of test* of either 1-610 or CN~6kO ware available for evaluation. Therefore no consent ean be made as to the actual range of quality of either du font's or Caleo's production. A few tesu of Clldden's rutile pigmenu shewed inferior chalking, gloss end color retention. Since results of tesu la automotive anseals'nay net correlate with performance la ell or allqrd house palnu or in emulsion paiau. Titan!vas Pigment Corporation is Initiating as extensive series of teats to cover these polau. The tesu will include various leu of UK la lead-sine-titanium.extender tint hue home paiau, in nom-raactive pigment tint hue, la alkyda and In muilsicn paints, u well as the usual automotive enamels. 2. Op to this year du font has promoted a lover cost leaded tlne-TlO*-calcium carbonate pigmentation. To Improve the durability of a white of this kind they had recommended that up u 1/} of the TiOg be non-chalking rutile t-610. Color wu net toe good for a white. They now report that upon prolonged exposure such a paint shews good film retention, but eventually shewed checking and cracking. They now prefer for a lew cost house paint a lead-free formula, using one pomd per gal lon ef pure sine oxide, with calcium carbonate, which shews no or vary lietle cracking at five to six years. 9. He did net have time during the ASSM meeting in Atlantic City to go to Oesan City, Mew Jersey to inspect Che house tuts ef caulsion paints reported last year. Dr. Vaanoy suted that resulu this year varied, sometimes to the advantage ef acrylics, and at other times to the advantage of polyvinyl acetate 81-900.

This series should undoubtedly bo expanded, including both panel and house testa, and adding Aside (0.7> fb) to the Id H paints new ia the series. du Pone has a supplenaatary series ia which Green Gold wes used with various extandors, ell substituted at equal oil donnads.

Vo had reported to du Pent that we had seen sene instances where K-110 chloride process (sane as *-J10 chloride process) showed sere tend ency toward rutile yellowing than t-110 sulfate process. We had seat thou one of our sets of penal exposures to show this, and their labora tory agrees our panels are elear exhibits of our point. Op to aqr visit they had never seen this ea their own panels. However, the hxsid, rainy weather on the day Z was at their fans brought out rutile yellow ing. Tha chloride process t-110 or J10 showed definite rutile yellowing, the k-110 sulfate process did not. This caused considerable axcitsnant snoug dta du Pout personnel as the chloride process offers than the beat opportunity to expend their production.

Cocmerclal Paints Ona eat of tbeaa paints was prepared in Juno of 1952 as three coats self-primed on cedar and white pine and exposed north and south vertical. Lead in oil, of course, is badly eroded with bad checking in what fila remains. 60/30/10 laad-siac-antendar paint ia checked and worn as would be expected. A Ti-Sil" type of pigmentation, 50$ 55 leaded siae/50^ titanium magnesium is in much better condition but flaking at the lover edges of the panels.

Among the ceemarcisl points SNP Glees Uhlte is ia good condi tion except on the one bad pine board which has bean mentioned in previous years. Devos's paint is very yellow sad does not present a good appearance. Pateersoo-Scrgene's white is good on the south but mildews badly on tike north exposure. Benjamin Moore's is fair, with seme erosion. National Lead's #110 white is whiter than SUB kjl on the north, but ia showing allt cracklng,not evident on 3x Vfl. The same series wars put cut In June, 1953 0(1 the sssm sur faces. Both the lead end oil and the 60/30/10 are behaving as expected, with much less failure than was shown by the additional year of exposure of the 1952 series. The 60/50/IO paint is much better on cedar than on white pine, behaving as expected from the classification of woods. The Ti-Sil-' type of paint shows slight edge flaking on the south and is thinner on the north than the commercials discussed below. 2n the 1953 socles of comsercial paints SUP Gloss Uhlte is in perfect condition south and north, except for ehe slight yellow cast on tha north. Benjamin Moore paint is in very good condition, as is Patterson-Sargent, exespt that the latter again shows mildew, this time slight on both south and north.
