DESCRIPTION: A multi-component product consisting of a pigmented base and activator. Companion products are an optional Dry Time Accelerator 189 S, 259 S Imran9 Additive tor fish-eyes and 8485 S Imran Reducer. PERFORMANCE DATA: Excellent color and gloss retention, chip resistance, abrasion resistance, stain and mar resistance. Excellent chemical and solvent resistance. Outstanding resistance to yellowing. Excellent cleanability- Op tional faster drying rate. % SOLIDS BY WEIGHT: 47.5% as mixed. (This Is an average value which will vary with color selected.} % SOLIDS BY VOLUME: 34.0% as mixed. (This i3 an average value which will vary with color selected.) DRYING RATE: Tape free: @ 77F., 50% Rel. Humidity: 6-10 hours without accelerator. 2-4 hourswith accelerator. THEORETICAL COVERAGE: 544 aq. ft. at 1 mil. (This is an average value which will vary with color selected.) RECOMMENDED FILM THICKNESS: I S to 2.2 mils dry film thickness. POT LIFE: 8 hours minimum at70-75F. FLASH POINT: Below 80F. DIELECTRIC STRENGTH: Approximately 2 kilovolts per mil over steel, 8 kilovolts per mil over fiberglass for solid colors. Metalllcs have much lower values. REDUCTION RATIO: Mix three parts IMRON Polyurethane Enamel with 1 part 192 S Activator, four ounces par gallon 189 S Accelerator can be added to increase drying rate. Two tD four oz./gal. of 259 S Imran9 Additive should be added to prevent fish-eyes. Far spraying of large areas material may be reduced further with 8485 S Imron* Reducer or 3979 5 Retarder. APPLICATION: 1. Treat bare metal with Du Pont's recommended metal treatment system. Bare fiberglass should be scuffsanded and solvent wiped with 3812 S. follow with CORLAFf Epoxy Zinc Chromate Primer or Multi-Purpose Primer. 3. OEM finishes (except lacquers) and aged alkyd or acrylic enamels should be cleaned with 3919 S PREPSOL* and Sanded thoroughly with #360 wet or dry sandpaper.
