(e) Shade with the principal colors, selecting the tinting pigments which will require the least shading to obtain the desired color. This will result in the simplest formula and generally the most durable * (d| Repeat trial pigment combinations until It appears that a simple preferred combination will give the proper hue. (e) Tone with the most preferred and least expensive tinting colors, (f) When an approximate shade is obtained, calculate the pigment composition on a 100^ basis. .(g) Determine whether the original color .classification was correct under (a). If not redevelop In accordance with the proper color classification section. (!r) Each classified section is divided into a preferred and alternate allowable pigmentation, separated by the statement, "If the color can not be matched with the preceding pigment com binations, the following toning pigments may be used/* All possible pigment combinations in the preferred section should b tried before using the alternate preference, (1) When the final color match is obtained the pigmenta tion should be broken down to a 20Q# basis and rechaeked against the pIgmentatIon"practice . U) All possible durable pigment combinations cannot be covered in a formulating practice. If the formulator believes that a combination of pigments outside the practice is durable It should be referred to the Marshall Laboratory for special consideration before using. DUP030029236 {k} There are many eoscm errors ssde r eo'.or development; which result In excessive cost, inferior durability, and sianufasturlng difficulties* These errors generally result free* a. viola tion of one or- sore of the following basic formulating rules - (a) Keep number of pigments to a minimum, Most colors can be developed with no sore than tyo color pigments, black, and white (b) Dp not blend complementary colors % Complementary colors, 1 ,et,., red and green when blended together result In black. A more durable and cheaper product results if a blade pigment Is used, (e) Po not blend colors with complimentary undertones,, A typical example of this malpractice' is a blend of red-toned blue and blue toned green {W-51.9 and W-7&5). The resulting formula is excessively expensive,, (d)' Do not use llghffast pigments to tone fugitive col ore ,, 0v) Of course there are exceptions to the rules .and procedures. To permit control and minimise the responsibility of .individual fo.rmulato.rs for field performance of new developments. It is ,r.ecom~ mended that formula development of a questionable composition be submitted to the Marshall Development Laboratory for review and approval, (S) -Pigment Blending Practice Tinting iiitea and Toning Blacks The two pigments most common to all blends .are white and black. There are two white, W~2<?3, Titanium Bioxide, and W~50 Titanium Dioxidej /and two blacks, -233,? Baptised Carbon Black, and Carbon Black, W-123, Butlle "Ti-Pure"R-900 This pigment is restricted to use in preparing white enamels only ir the 873-Line quality-. W-50 Rutile wTI-iur" B-610 w-50 should be used in developing all colors in the 873-line due to its -jxeellent chalk resistance, DUP030029237 `J-f-ji is to be used as the toning black in a.X motors and whites including light, media, an!dark gray enamels due to its excoliero, ao^or drift stability, W-?4y darbps Black This pigment is restricted to the development of solid black enamels in the 8T3-"jtine >, At times it tsay be necessary to use W-~24 in the formulation of dark grays due to the high .cost and weak Mating .strength of W--253 or the Impossibility of matching the color .with W-253* -tn these extreme cases Sales should be advised of possible color drifting when W-224 is used. Determination of 'Proper Flatting Base for Whites There are two flatting bases developed for use In the 873-Line#quality as follows; la.) 902-5001 based on a W-135/K8-8025 pigment combination 'which is to bs used in the manufacture of all colors - 902-5001 should also be used to manufacture whites in which the "S" value Is greater than 3 between an unshaded 873-Liri@ whits containing 90? 3001 ancl tne; standard to bs matched It is Important that the formulator adjects the gloss to the customer's specifications before testing the feasibility of employing 902-3001, This particular flatting base is preferred because of its contribution to good physical properties such as impact adhesion, bend flexibility ad hesion, and durability, <bj> 902-17927 based on a W~X38/KS~8025 pigment combination imparts a higher initial reflectance to an unshaded 873-Aic.e white but at a sacrifice In the above mentioned physical properties,. However, In some instances due to very high initial reflectance of the white standard to be matched It will be necessary to use 90i> 17927 in place of 909-3001 . It Is the responsibility of the individ ual foramlator to determine whether it is necessary to employ 90217927. If thi* white standard cannot be watched satisfactorily with 902-17927 because of exceptionally high initial reflectance then tie problem should be referred to the Marshall Development Laboratory, USE OP W-679, CHROME BELLOW, W 873-L1HE WHITES IMP COLORS Toe vehicle -composition employed in the S73**Lihe has a DUP030029238 si igT:1 I?,, r e-,e raise lend.rn-ey *o pii*ow on eaterlcr expcuiile, fiisi degree af ;OKing that takes place la relatively prcw;Hi.ae,, ss;ountl;iig to a tGiti *'f.

In the stripcoating^industry nearly all whites and certain color are shaded on the yellow side, A satisfactory system has been de veloped to counteract this vehicle yellowing fey the use of a con trolled amount of fugitive yellow pigmentation (W-679) In developing these enamels in. the .quality. It is important that the -679 not bfs rased Indiscriminately as a shading tool particularly since there are a wide range of whites* including high reflectance whites that require very little shading and low reflectance whites that require a substantial amount of tinting* Ie, more than an "E" of -two units when measuring an unshaded whit versus the color standard to be Hatched,, The following procedure should be used as a guide oy the formulator for matching whites in the 873-Line quality., (a) Sigh Reflectance Whitest Initially the fonmalator should check the total E color difference between an unshaded white in 873-Line quality* which has been adjusted to the customer s gloss requirements versus the- standard to be matched,, See section of TDetermlrsattor* of Proper Flatting Base For Whites" For high reflec tance white enamels based on 902-17927? (1) If the -"E" difference Is less than 2 units then use only 902-679 if yellow Is needed to match standard. (SI If "Em Is greater than 2 units and yellow Is neces sary then add IPS'-679 to effect a total B color change of approxi mately 2 units ,, Th& amo.unt used should be recorded accurately in IPs*., with a notation to be weighed in grams* and shown as an "on load" addition on the formula. For plant batches that vary In size the amount of (102-679 should be reallocated as any other principal Ingredient in the formula* Any additional shading of yellow should be conducted with 902-630 or 902-608. IT IS IMPORTANT THAT THIS PROCEDURE HE FOLLOW AT ALL TIMES . Cb) Low Reflectance Whites?

If possible. (3) If no yellow is required In making the color match then disregard (1) and (2). (4) if additional yellow Is needed (more than 0.4 lbs.) then me 902-608 or 902-630 for the additional shading. ADDITIONAL DATA CQNCERMI1G THE .MANUFACTURE OF WHITES (!)
