Since there are at present seventeen active grades of aluminum pigment pastes, some simplification of this structure was considered highly desirable. This work was designed to study the majority of the active aluminums in automotive metallic'and to select the preferred candidates, based on the optimum brightness, two-ton effect, .gloss, and resistance to leafing, settling, and seeding. SUMMARY AID CONCLUSIONSg 1. Of the fine grades of aluminums examined, -82 (Alcoa #1590) gave the Self balance of properties in both "Du g o and "Dulux" metallic. (Tables I and XX), and is-classified .as the preferred fine grade aluminum. 2. In the medium-coarse grades W-100 (Alcoa #1595) re turned the optproperties In "Duco" .and "JDaltuc" metallic enamels, (Tables I and II), and is classified as the preferred aluminum for this grade. 3. Among the coarser grades -80 (Alcoa #222) and VI-81 (Alcoa #240) were aSouT equivalent in properties in "Duco" with the exception of a high rate of settling for VI-80. Xn the case of "Bulux'8 W-80 was slightly better than -8.1 in strength. Both these pigments have been classified in the WC" group, X.e. restricted to existing products. WVJ* 1' .cf'- N 29330 AC1X0H wmm OR pr o po s ed ? The Figments Dispersion Committee has reviewed the currently active aluminum pastes and have classified W-82 as the preferred fine grade aluminum, and W-100 as the pre ferred medium-coarse grade for ''Duo*5 and "Pulux". Six of the aluminums have been proposed for obsoletion (Table ill). Currently the Flint and Parlln Laboratories are in process of a plant alignment program to replace -173 with -82 in 282 Line fine aluminum tinting for "Due" metaliics, Release Letters F-523 aKiS ^*"529 proposing release of W-100 aluminum for metallic "Due" lacquers and metallic "Duluz" enamels have been written and approved. EXPERIMENTAL DETAIL Preparation of "bulux" and "Duco" Metaliics Three lots each of sixteen eiucrently active aluminum pipient pastes from the Aluminum Company of America, and Reynolds Metals Company were formulated Into 32 Line mill bases and 282 Line tintings at equivalent aluminum-metal content. Using w-82 pigment paste (Alcoa #1590) as a control for degree of lightness the aluminum tintings were let down into complementary gray "Dulux" and "Duco" metallic enamels shaded both lighter and darker than the W-82 control. Pearlboard spray-outs were pre pared from these enamels and lightness values ("G") determined with the Colormaster (DuPont Differential Colorimeter), Semilogarithmic plots of "GM values versus pounds of aluminum tinting were prepared for each pigment paste which gave a theoretical value of pound of tinting required for each pigment to match the degree of lightness of the W-82 control pigment. "Duco" and },Dulux" metaliics were then prepared for each pigment past employing the theoretical pounds of aluminum tinting required for lightness equivalent to the W-82 control, (See Table III for enamel and lacquer compositions}. Panel Preparation t The "Dulux" enamels were applied over 4" x 6" aluminum panels undercoated with 765-1676 baked at 4011 at 280F, and dry sanded, The enamels were applied. according to T.M. 349-A ''Spray Procedure for "Dulux" Metaliics" and baked 30' at 240P, "Duco" lacquers were applied over 4" x 6" aluminum panels undercoated with 475-1195 surfacer baked 60* at 200according to TM-95-D, "Color Matching and Control of "Duco" Metalli-Chrama Colors' and baked 20' at l80F. The panels were then buffed and polished. Properties; Strengths Panels were graded for lightness, "G" values, on the Colormaster(DuPont Differential Colorimeter) and from these the theoretical pounds of aluminum tinting required for each lot of aluminum pigment paste to match the W-82 control lightness were obtained, by locating these "a"- values on the clots previously established for each pigment paste-. DUP030000732 A 3 Assuming a straight-line relationship feetween lightness versus pounds of alumlnuia tinting, a parallel line was drawn through the "0" value obtained, and the point of intersection with the 82 control curve was considered the actual amount of aluminum tinting that would fee required for equivalent lightness. A strength value was calculated for each aluminum paste ass , 100 . length The individual tintipgs for each lot of aluminuia.were rated for leafing after one week shelf storage. The degree of aluminum float in the can was rated on a scale of 1 = no leafing to V considerable. Settling? The degree of settling of the aluminums was rated after one week shelf storage of the ttettegs, by stirring gently with a spatula. The amount and denseness of the cake in the bottom of the can was'rated on a scale of '1 pone to 10 a hard cake. Glosst Panels were rated for 20gloss on the Glossmeter in accordance with AvS'.T.M. standards. Test Method TM-204-B. In the case of "Buco" the panels were rated after huffing. Two'-Tons % Panels' were also rated by an instrumental method developed at Marshall laboratory. This method employs a goniphotometer to measure nlightness ' or reflectance at two angles of viewing. The ratio of the "lightness" at the greater viewing angle to the smaller angle Is expressed as a measure of the twotone effect.of metallic finishes. Seed? The tendency for the tinttegs to develop- seed was determined 'after six weeks shelf storage. The enamels were reduced to constant viscosity and flowed out over glass* Plow puts were, examined visually under a constant light source .and rated on a scale of .1 - none to' 10 - severe. It is of interest that in the case of - "Dulux" ignlficant .differences in seed development were observed between the various grades of aluminums. The fine grades of aluminum developed very little seed while the medium and coarse grades... developed objections! seed. It is also of interest, that -100 (Alcoa #1595) th preferred medium grade did not show objectionable seed. However, in th case f "Bus" tinttegs very little seed was "apparent even in the ease of the coarse grades of aluminums.

The study m concerned with two major parts s (1) the colorimetric determlaation of the "brightness" of the qornaercially available aluminum pigment previously studied and discussed in the original memoran dum report F-101, and (2) the preliminary investigation of the practice of blending the preferred grades of. aluminum pastes to accomplish the optimum in brightness, two-tone, gloss and resist** . anoe to leafing, settling .and seeding. The majority of the commercially available aluminum pigment paste from Reynolds Metals Company;and the Aluminum So. of America were examined as well as several experimental grades fro these suppliers. Several blends of the preferred grades defined by the first phase of the work w@?e examined in an attempt to demonstrate that such a system embodying the desired features of each grade is a commercially practical route toward simplifi cation of the number of grade now required to formulate difficult to match metallic colors, smwx xw..c<MSwm.* . ., * 1, Of the fin grades examined, -82 (Alcoa 1590) returned a marginal advantage In brightness and the best balance of other properties in both "Duco" and "Dulux" (Tables I & II} and is classified as the preferred fin grade aluminum, .2 2, In the medium-coarse grades the us of ***100 (Alcoa 1595) results in a decidedly brighter ta@tal.lic as well as returning the optimum balance of properties in "Duco" and "Dulux" (Tables X as XX), In this connection three experimental "improved grades" of Alcoa 1595 (-100) examined in th course DUP030000741 ~2- of this work showed a significant Improvement in two-ton effect ofs? -100, Other properties were essentially equal, Also a sample of Reynolds0 improved 49-L paste,- Ho, BD-I69, returned improved strength, gloss and two-ton oyer ttf-100 past in "Bulux" with other properties including brightness, being .equivalent, - This aluminum, on the basis of the on sample-exam ined, appears to be a suitable alternate for the preferred -100 m&lura-coars grade, 3 Among the coarser grades -81 (.Alcoa 240) returned the hipest order of brightness, and optimum balance of .other properties with the. exception of a high order of seediness In "Duluxtt In this connection -80 (Alcoa 222) although not as bright as -81 is equivalent in other properties and less seedy than W-8l, Both of these pigments have bedn classified in the "C" group ,e, restricted to existing products, 4, Th results of the preliminary work done with blends of aluminum pastes indicates that brightness and two-tone is im proved as the coarser aluminum content is increased in a given blend (Tables XIX & X?) Conversely, seed particularly in rtDuXus" increases and gloss and .strength decrease as the coarse aluminum ratio .increases.. From the limited data available it appears that any single property for a .given aluminum blend is a linear function f the ratio of the grades of aluminums employed (Tables XXX & IT) In the as of wDnlux" one encourageing result noted indicated that an equal blend of -100 and W-8l aluminums .returned good tw-toneness, brightness gloss and strength? accompanied by a significant improvement in settling and seed over W-8l the aiumin- ., mis which /results in the best two-tone and brightness ' (Table XT), This combination of ..aluminums appears worthy of further and more detailed study, A0TI0H TAKBH 03 PROPOSED* to the basis of this work the Pigments Dispersion Com- mitt. has classified W-82 aa th preferred fine grade aluminum, and -100 as the preferred medium-coarse graHeTor both ,JDuco" and KDulux", Recently encountered competitive metallic color matching problems have pointed up the advisability of blending different grades of aluminums in order to be 1GG$ competitive. Our suppliers have advised that this practice is being adopted by our competitors 0 In view of the encouraging preliminary results realized with -100/ 8l blends in ''Dulux" it is proposed to investigate combinations of these aluminums on a broader and more detailed basis.
