S, Waritz, and G. L. Lescanec of the Haskell Laboratory, We wish to obtain comparisons of the hazards involved in spraying the following paint systems: 1. Model II - experimental polyurethane 2. Model III3. Competitive polyurethane (U.5. Paint) 4. Corlar catalyzed epoxy 5. Flintflex moisture cure polyurethane --6; "968 Lir 7, 93-Line Dulux enamel Complete ingredient identification will be supplied by us when materials are submitted. <W.| __ _ Mq s /u J/ 46s , 3*93/ -- S'?**?

October 29, 1968 2- - Although we had agreed on testing clears only we cannot obtain the competitive material as a clear* We shall therefore supply all systems as white enamels. The two package systems are to be mixed 1/2 hour before testing, A six hour induction period may be specified for testing at a later date if initial testing warrants it. Tests to be run are: - 1. primary irritation and sensitization 2. eye irritation 3. spray inhalation - one hour exposure to spray mist, I understand you will submit a project for our approval and work will begin as soon as possible following this approval.
