2 In-line measurement and correction of Color and physical properties Symposium on Color and Appearance Instrumentation April 15-16, 2003 Chicago, IL Girish Malhotra, President, EPCOT International, Pepper Pike, OH, USA Carlos Arthur Peixoto, Process Engineer, Eduardo Schotgues, Software Engineer, Paulo R. Pfeil Instrument Engineer- NTP Production Technology Center, Renner Herrmann SA, Porto Alegre, Brazil

3 CHARACTERISTICS MEASURED COLOR PHYSICAL PROPERTIES DISPERSION PARTICLE SIZE

4 IF SPECS CAN BE CORRECTED AND MET WITHOUT SAMPLING BENEFITS WILL BE: REDUCED PROCESS CYCLE TIME IMPROVED PROFITABILITY HIGHER AND CONSISTENT QUALITY

5 TECHNOLOGIES COLORCELL (REFLECTION ONLY) MULTICELL (TRANSMITION AND REFLECTION)

6 Fixed Plate WIPER Spectrophotometer Reflection Liquid COLORCELL TECHNOLOGY SCHEMATIC Figure 1

7 Fixed Plate Movable Plate WIPER Spectrophotometer Reflection Transmission White Light Liquid Transmission MULTICELL TECHNOLOGY SCHEMATIC Figure 2

8 Electronic finger print is created and matched. Figure 3 MULTICELL

9 TECHNOLOGY APPLICABILITY COATINGS (ARCHITECTURAL, AUTOMOTIVE, WOOD, INDUSTRIAL, PAPER) PRINTING INKS PIGMENT AND DYE DISPERSIONS TEXTILES COLORANTS COSMETICS FOOD MINERALS

10 MULTICELL TECHNOLOGY WHITE LIGHT vs. WHITE BASE REFLECTION AND TRANSMISSION THROUGH FILM MEASURED CONTINUOUSLY ELIMINATES USE OF WET STANDARDS CONTINUOUS COLOR, STRENGTH AND HIDING POWER MEASUREMENT CONTINUOUS VISCOSITY, DENSITY AND TEMPERATURE FEED RATES ADJUSTED IN LINE TO PRODUCE QUALITY

11 TECHNOLOGY (cont.) DEVELOPED BY RENNER HERRMANN, S. A. COMMERCIAL Du Pont Performance Coatings Automotive refinish coatings (Brazil) E. I. du Pont - Mt Clemens Automotive primers (Michigan) Renner Sayerlack (Brazil) CADAM ( Caulin do Amazonas ) Other installations underway

12 FINANCIAL IMPACT INVENTORY INTEREST OBSOLESCENCE MANUFACTURING COST REDUCED WASTE SERVICE AND QUALITY

13 FINANCIAL IMPACT Savings 15-25%

27 SUMMARY TECHNOLOGY IS COMMERCIAL. PRODUCTS DEVELOPED IN ANY PART OF THE GLOBE CAN BE PRODUCED AT THE MOST COST EFFECTIVE PLACE. TECHNOLOGY CAN BE RETROFITTED IN EXISTING PLANTS. MARKET AND PRODUCT DEVELOPMENT TIME IS SIGNIFICANTLY REDUCED.

28 THANK YOU VERY MUCH. QUESTIONS CONTACT: Girish Malhotra, P.E. EPCOT International Bryce Road Pepper Pike, OH (P) (F) Profitability through Simplicity
