'<~a.^a.rir \\ ov<-?r < H ' k-^ C- In regard to house paint tints, some day ve nay vlsh^to use rutile titanium as the white pigment'in view of its .greater >*r c^rp? tint retention and the high cost of lead* Ve do have some houses painted, vhioh have been on exposure for a year and the oolor retention is very good. There is also a possibility of improving our house paint primer by replacing the anataee with rutile. Krebs have tests which indicate that even though the primer Is not exposed the use of rutile improves the durability of the top ooatB. Ve likewise have exposure tests tinder way. Ve do not anticipate this change for some time. i- vt*v Second grade house paint known as Everon, Y-2200-K, based on soya-wood oil vehicle was developed and turned over to the V* sales department. A set of exposure tests appeared to be satisfactory for this type of paint. This is more of m quality second grade paint. Some thought has been given vf^ - to changing this formula to an all eoya paint. However, in view of the closeness of the price of treated soya to wood "l oil the there paint would could not be any great saving other than be marketed as an all soya paint. the The vfaechticle 17 .V? -s now based on &0 per oent soya and too per cent wood. tl'-0 /t<* In regard to the development of a new Endurance and Master ,Si Painters Elat, it has been our policy to follow good paint practice and recommend a primer sealer over porous surfaces. However, one coat flats have been introduced on the market which are based on limed vehicles with a high pigment ratio. These flats do not have the quality of our regular flat. In L 'V - . n* %-i 5V*iyC s V5 - '* _3 view that they did meet the popular demand in regard to fool- oroofnesB over porous surfaces it was decided to retain the quality of our old flat and at the same time improve the hold jut properties over porous surfaces. Extensive tests have been iade in both the laboratory and in the field and the flat does ~ perform satisfactorily. This formula is known aB Y-470Q-B* .'he new flat utilises polymerized oil rather than the lime treated as we have found any savings the lime treated oil may vave is offset by the required use qf special colors. Polymer ized oil also giveB a harder drying film. -C his ie the second time this flat, has been changed within elx months. The first time the formula vat changed to step up the aiding with titanium calcium pigment and was veil received by the trade. Both changes were made at the request of the sales iepartment and are only mentioned to show the continued work on trade sales products vhloh at times seems to be necessary to >ieet competitive conditions. I'here is a considerable demand in the trade for a low cost one ; joat enamel. These enamels are generally based on a plasticized rosin vehicle and 'there is little or no, profit in their nanu- : "nature and sale. In order to hare an. enamel-with special, idvantages it was decided to make a higher grade prpduot in < rolume and which would have special advantages over other type jnaaels used by the Master Painters, The last part of the year this was accomplished in our new Y-5045. s .This, enamel-has ^he *; musu&l easy, working in ooap&risDn with other enamels and its - lft - Gl037096 I9a^ hold-out properties over porous surfaces are remarkable,'5 Hast enamels applied to porous surfaces ,or, beavtrboard r, will soak in whereas this type of enamel will.present \.k good appearance,'.In this particular Vensael^ve are .using ? competitive vehicle and ve are studying this further in , v` an effort to determine the reason for Its excellent hold out and easy working properties as undoubtedly ve can not only produoe it at a lover price but also these properties should be of Interest in other vehicles,. For example, easy brushing is analagous to. easy spraying and with. the cost of labor as high as It is we may obtain a. lead on how to develop an easy spraying vehicle. In order to continue to meet competitive conditions ve can expect our expenditures for 19^9 to be.in the aame ratio as the first quarter - this will mean an expenditure of 520,000 for the year. PETROLEUM DRYING OILS $2,^93^99J5 I,?*? iV-j / uA /f. $39h.oo A joint program has been in existenoe between the Gliaden Company and the Universal Oil Products Company to investi gate and exploit a synthetic drying oil known as *Unlvoll." Twenty-eight different U.O.P. oils vere studied as veil as a number of competitive products. Copolymers of these oils with vegetable oils and two maleic adducts were also invest!- , tjgated. The Univoils alone yield films which are brittle, thermoplastic and have poor resistance to weathering, Formu- , r latlon along the lines of typical v&ra^sh practice Indicates that the presence of fairly small amounts of' the petroleum, oil or Its produots deteriorates a film with respect to outdoor V durability and Induces brittleness. Fractionation of the complex mixture of compounds known aa Unlvoil with solvents, oxidation vith various reagents, and reaction vith formaldehyde nave failed to yield compounds of apparent value, .4-- in December 8, 19^8, at a Joint meeting held with U.O.P. In ^ Chicago it vas disclosed that some success had been attained ' in preparing copolymers of isobutylene and butadiene. One of t" these polymers has been examined. It air dries in about six hours to a tack free ,rilm which becomes brittle in a few days. The films tend to wrinkle badly unless they are very thin and have almost no film strength. Films vith and without pigmenta tion baked at 30 and ^50 F. are very hard but lack adhesion and flexibility, !Clear, air dried films of the polymer fail in less than 70 hours in the veatheroaeter - corresponding to two to three months of outdoor exposure, Future work will depend on the ability of U.O.P* to produce oils' vrhloh are superior .to those already submitted. Samples.of a duPont synthetic oil have been promised and will be examined, . This oil is reported to resemble the natural oils more closely than the petroleum oils do. In addition, a routine study will be. made of other new products as they are offered by the Industry,^ . . . '_<> * Depending on the results of hew samples from U.0.JJ. and duPorit,our expenses should not be greater than $2,000, f: / >.... IS - Gt D37099
