However, since we do not know how these regulations will ultimately be Interpreted we are suggesting the following: (1) Consider the use of substitute driers when lead drier or litharge ere presently used and other lead pigments arc not being used (l.e., Metalastlc II), (2) Suggest possible replacements of red lead or basic lead sillco chromate (primers). (3) Summarize your position as to what car. be done to formulate a relatively non-toxic primer keeping In mine that chromates ray be curtailed in the future. At this time we do not need to sake formulation changes but the purpose of this letter is to develop information and to stimulate your thinking, so as to protect ourselves from being caught unprepared against potential restrictions, j Attached is a list, by laboratory, of the products tn be considered. 0007--SWP--038210 V c c CONFIDENTIAL Our approach: Phase I (1) Do you already have any infomation on lead free alternate formulas? How do they compare to lead containing line Items? How are properties effected by lead removal; 1. e#, Tile Clad II and C&H primer without lead pigment? (2) Have yon looked at alternate lnhlbltlve pigments such es Zinc oxide, zinc molybdate, Susan, zinc dust, etc? (3) What other approaches can we take l.e,, increasing chemical resistance of vehicle? (la) Kow tolerant are Zinc Rich coatings of a lesser degree of surface preparation i.c., Zinc Clad 5? This may be an approach in case our lr.hibitive primers are severely restricted. Phase II Develop and evaluate lead free alternates in case ve need to make a change. Remember -- we said develop not revise. j ^ J We would appreciate your comments. 0007-SWP-038211 OQ07-SWP-OOO110392 V r~ r CONFIDENTIAL PiPtlSTRIAL MAITTEFAN'CS FP.OPil.TrS coKii';::: l f a d .via h s a v y KTTAIS Chicago Galvanized Iron Prlnor Ken Bond Primer Kromik Primer Tankelad AVWA Vinyl Systen Light Cray Medium Cray White 8SO A 1 ELI 11 IS ELI II 1 B69 A 26 B69 A 27 B69 W 27 E90 E CJ Korrov KetalastLc II Kem AW.
