    1. DuPont® Fluorosurfactants Industrial and Institutional Applications

    2. What are Zonyl® Fluorosurfactants? Where are they used? Why are they better? How do I contact DuPont for more information? Introduction to Zonyl® Fluorosurfactants

    3. Zonyl® Fluorosurfactants main uses I&I Waxes for wetting and rewet in multiple coats Wax stripper concentrates for surface tension lowering To lower surface tension and reduce surfactant usage levels in many applications Work in combination with existing surfactant package to enhance overall performance of the surfactants while reducing total amount of surfactants necessary

    4. Surfactants And Wetting Surfactants Lower Surface Tension of Liquids and Improve Wetting and Spreading

    6. Focus on Industrial and Institutional Cleaners Wetting, Penetration, Decreased Surface Residue, pH stability FSH, FS-300, FS-500, FS-510 Floor Waxes and Polishes Wetting, Leveling, Rewetting FSA, FSJ, FS-610, FSO, FSH Other Markets in I&I Wax strippers Glass cleaners Commercial vehicle cleaning

    7. Decreased Surface Residue Glass Cleaners, Cleaners For Shiny Substrates Fluorosurfactants are useful in cleaners requiring - Minimal residue (decreases streaking or smudges) - Wetting - Penetration - Reduced drying time - Cleaning power Recommendation: Zonyl® FSH, FSA, FS-610

    8. Floor Waxes Fluorosurfactants are used in most commercial floor waxes They provide: wetting and rewet for multiple coat systems easy spreading and leveling of the wax system lower scuffing and dulling of the floor finish no impact on gloss levels ability to comply with “Green Seal”

    9. Surface Tension of Commercial Fluorosurfactants in Rohm & Haas RHOPLEX® 3829 Floor Polish

    10. OECD 301b Testing Zonyl® Fluorosurfactants that pass OECD 301b test methods: FSA: Anionic Surfactant FSE: Anionic Surfactant FS-300: Nonionic Surfactant This is required for European detergent formulations (EU 648 Directive) and is important to meet today’s market needs.

    11. Metal Surface Modification Fluorosurfactants chemisorb strongly on metal surfaces which offers numerous benefits: Stability in alkaline cleaner concentrates Reduced “dragout” Reduces amount of chemicals depleted from bath when metal parts are removed A metal surface resistant to flash corrosion, repellant to water and oily soils, and readily accepts a coating Keeps metal parts looking cleaner, longer

    12. Metal Surface Modification, cont. Increases Mold Release: The adsorbed monolayer of surfactant lowers the surface energy of the mold Decreases tendency of parts to stick to ceramic or metals molds Also used on stainless steel belts for polymer film release

    13. Zonyl® Fluorosurfactants are Cost Effective

    15. Zonyl® Cost Effectiveness

    16. Zonyl® Fluorosurfactants and Hydrocarbon Surfactants Work Together for Improved Wetting and Spreading!

    17. Why use Zonyl® Fluorosurfactants? Unparalleled wetting power You use less… usually 10 to 30 times less. Cost effective Leave fewer residues When mixed with hydrocarbon surfactants you can reduce their usage Less chance to react negatively with chemistry formulation because of low use rates Function in harsh chemical and thermal environments, and across wide pH range where other surfactants will break down Function in solvent systems and aqueous systems

    18. Compliance of DuPont™ SPS* products with the European Directive 2006/122 DuPont™ SPS products are in compliance with the European Directive 2006/122 relating to restrictions on the marketing and use of perfluorooctane sulfonates (PFOS) (amendment of Council Directive 76/769/EEC) PFOS is not used or added in the manufacture of DuPont ™SPS products In fact, DuPont™ products are based upon a completely different chemistry than that associated with PFOS Please note that perfluorooctanoic acid (PFOA) is not part of this directive, and there is no European Directive to regulate PFOA. Also note that the Norwegian market and use restriction proposal for PFOA has been put on hold in favor of REACH.

    20. The First Step: DuPont LX Platform products Based on DuPont innovative, patented technology $22MM investment in new manufacturing process Impurities: Dramatically reduced Meet 2010 EPA stewardship program objective for PFOA, direct precursors and higher homologues >97% reduction of PFOA and direct precursors Target product content at < LOQ*: PFOA Homologues Direct Precursors Performance: Best in class Drop-in replacements require no re-qualifications Listed on global regulatory registries (no registrations required) Strong history of customer success Available today: LX product line available in market in 100+ products

    21. The Next Step: DuPont™ Capstone™ products Maximum performance, minimum environmental footprint Performance you can count on - Same or better performance without a compromise in fluorine efficiency Putting our science to work for you Step change reduction in trace impurities below the limit of detection* Short-chain molecules that cannot break down to PFOA in the environment www.capstone.dupont.com

    22. DuPont™ Capstone™ products A broad portfolio of sustainable, performance driven fluorine-efficient repellents that meet or exceed global market performance requirements. Capstone™ products are based on short-chain molecules that cannot breakdown to PFOA in the environment.  This change, when combined with the technology for LX Platform products yields fluorotelomer products with negligible PFOA and PFOA precursor content. Short-chain products are based on chain lengths containing six or fewer fluorinated carbons.

    23. Why Capstone™?

    24. DuPont™ Capstone™ products Availability: DuPont has the largest short-chain telomer capacity in the world Recently expanded capacity by 3x for short chain telomers DuPont currently offers short-chain products in 4 segments that meet specific customer performance criteria. DuPont has a product plan that will allow the transition of key segments to short-chain chemistry by the end of 2010 Products and samples will be available over the next 12-18 months to replace LX Platform products

    25. DuPont™ Capstone™ products Environmental sustainability and performance equal to or better than current DuPont products. Conversion to Capstone™ products further reduces the global footprint without compromising performance and fluorine efficiency. Performance in end-use applications is similar to traditional LX Platform products. Listed on existing global regulatory inventories, including the US (TSCA), Europe (EINECS), and meet the goals of the voluntary U.S. Environmental Protection Agency 2010/15 PFOA Stewardship Program.

    26. DuPont™ Capstone™ products Technology Summary Meets voluntary US EPA 2010/15 PFOA Stewardship Program Commitments Product Content Profile: PFOA*: < LOD Direct Precursors: < LOQ (>95% reduction Rf8 and above) Indirect precursors: < LOQ (>95% reduction Rf8-2 alcohol (and greater) *LOD = < 0.5 ppm; LOQ = < 2 ppm

    27. Next Generation – DuPont Products Novel products based on proprietary technologies currently under development Will continue to provide superior performance Consistent with announced plan to no longer make, use or buy PFOA by 2015 Will provide additional benefits regarding environmental footprint Consistent with sustainability mission to increase shareholder and societal value while reducing the environmental footprint* along the value chains in which we operate.

    28. Summary Comprehensive, DuPont sustainability program - deliver high performance products with minimal environmental footprint - for today and tomorrow DuPont products are safe for their intended uses DuPont LX Platform products offer drop-in performance with > 97% of trace levels of PFOA, its homologues and direct precursors removed DuPont™ Capstone™ products are based on short-chain molecules that cannot breakdown to PFOA in the environment. This change, when combined with the technology for LX Platform products yields fluorotelomer products with negligible PFOA and PFOA precursor content. Next generation DuPont products are being designed to maximize performance with additional benefits regarding environmental footprint
