WIEJJKE LINCOLRWOQD As discussed by phone* we do not currently plan to divulge our formulas to customers and Air pollution control agencies* since Illinois has a Rule 66-Type regulation* solvent breakdown by photoreactivity class A* B* C and the percent solids should suffice. We suggest the following reply to Blectrographic corp.t > This is in response to your recent request for information about our paint compositions that you need to supply to the Illinois Environment protection Agency. The D Pont company has expended considerable effort in the past several years to develop finishes that contain a Mnimum of photoehemically reactive solvents yet maintain properties essential to product quality. For several years* we have sold paints to customers requesting them that conform to Los Angeles * Rule 66* we are rapidly reformulating most of our paint lines to conform to Rule 66 type regulations. We are also actively developing water-borne finishes and high solids finishes* use of which will greatly reduce solvent emissions * At the present time* about fifteen states* including Illinois* have adopted air pollution control regulations patterned after Rule 66. This Rule defines a photoehemically reactive solvent as any solvent with an aggregate of more than N38308 ./ 2 20% of its total volume composed of chemical compounds classed as shown below os which exceeds any of the following individual percentage composition 1imitations* A. A combination of hydrocarbons, alcohols, ate. having an olafinic type of unaaturation 5% A B. A combination of aromatic compounds with 6 or more C Atoms to the molecule except ethylbenzene 8% C. A combination of ethylbenzene, ketones with branched hydrocarbon structures, or toluene 20% The solvent composition of the paints about which yea inquired (expressed as percentages falling under each of the above classes) are shown below* product 655-1924 Black dealer 65-12X05 Gray primer 81-43325 gyean Bnamcl 61-43271 Black Snamel 81-43275 White Enamel 63-8095 Black primer A 0 0 0 0.01 .03 .1 12*TM. %. 1 13,1 1.2 34,0 5.0 81.2 9.8 83.2 6.8 23.2 4.8 76.2 3.4 Total 14.4 39.0 91.0 90,1 28.1 79.7 %-PM&L 33.2 66.6 38.4 34.8 51.1 52.7 DUP050049649 \ft l:;)` 3- 161-23994 Aluminum ha ,1 76.2 3.4 61-43313 Ned Enamel .03 7>0?Ti5 fd * 6 9.3 Total 79.7 77.7 77.8 % Solids 52,7 c *>f. ^<r> h' vo^\V' V #5<w Obviously, the solvents in those paints are photo- chemically reactive* However, we plAn to reformulate these products with solvents which are not photochemlcally reactive as defined by Illinois regulations!
