1 The Green Washer David Schimpff Director Research and Technology Developments in cleaning, pretreatment, and seal technologies that have changed our reliance on materials of questionable environmental impact.

2 Presentation Intent Current State Green Cleaning EPA s DfE safer product labeling program CleanGredients Cleaner development & validation Next Generation Pretreatments Environmental impact Performance versus conventional technologies Opportunities for reducing cost Sealer Development Performance versus conventional sealers Performance in the absence of pretreatment Opportunities for reducing cost The green washer Reality in today s marketplace

3 State of Green Cleaning Past 15 years Lower temperature Reduced from Hot to Moderate Temps Greater convenience Powders to Liquids Reduction in VOCs, HAPs, Phosphates Reduced performance green cleaning often required sacrifice Next 15 Years Lower Energy Cleaners must perform at F Reduction in packaging Concentrates, powders Eliminate questionable ingredients Phosphates, HAPs, VOCs Chrome, Zinc Improved performance green alternatives must clean like conventional

4 EPA s Design for the Environment safer product labeling program Recognized for Safer Chemistry

5 So what is DfE? U.S. EPA program In partnership with Industry, Environmental Groups, Academia Evaluated traditional and alternative chemicals for Human health concerns Environmental concerns Helped businesses select safer chemicals and technologies

6 Why look for the logo? Scientific Review of Ingredients Human Health and Environmental Impacts CleanGredients DfE Partners have Invested In R&D and reformulation Ensuring that they meet requirements Effective No product will be recognized without performing

7 General Requirements for DfE recognition ph No phosphates No HAPs Limited VOCs Prescreened Ingredients Low Toxicity Human and environmental No suspected carcinogens Sustainable Packaging Third-Party Proven Performance

8 Cleaner Development Sounds simple.. Prescreened ingredients Well-defined criteria Put a chemist on the bench and There was no category for industrial metal cleaning applications First industrial materials approved just 3 years ago Lots of low temperature surfactants Very few were/are low foam

9 Cleanliness Evaluation SQM200W, Surface Quality Monitor (OSEE Method) IPW-4001 treo SW- 61 Multi-TERJ 2112 ES treo SW Avg Avg Higher Values = Cleaner Surface

10 Green Cleaners in Application

11 Pretreatment Comparison Conventional Technologies High carbon footprint High water footprint Waste water treatment Phosphate Heavy Metals Proven performance Comfort in the marketplace Resource intensive Next Gen Technologies Reduced carbon footprint Reduced water footprint Much reduced waste water impact Demonstrated performance Growing comfort in the marketplace Reduced resource intervention

12 Market Observations Non-phos is hard to evaluate How do I KNOW the coating is on my part It s a GOLD coating, not rust..but it looks like rust I need flash rust protection Line stoppages are my reality I understand the benefits, but I need lower cost

13 Next-Gen non-phosphates Moderate Total Acid, ph Use anti-oxidants to Minimize potential for flash rust Better Visual Coatings Improved paint adhesion Enhanced corrosion resistance

14 SALT SPRAY Hrs. (B-117) Next-Gen non-phosphates Features Lays down coating much faster Heavier coating More intense color Commonly blue Benefits Increased corrosion protection Easier to see Reduced confusion of Gold / Rust 30 Seconds 80 F DuraTEC st Gen Non-Phos 804 EXP-DT20 2 nd Gen Non-Phos 90 Seconds 100 F

15 Corrosion Studies Sludge 3% Solutions, ph = 4.5, Mild Steel, 30 Days Static Immersion 1 st Gen Non-phos 2 nd Gen Non-Phos Rate of Corrosion 3% Solutions, ph = 4.5, 250 ppm Powdered Iron, 2 Days 1 st Gen NP 2 nd Gen NP 2 nd Gen NP

16 Pretreatment Technology Comparison Multi-Stage Spray/ Immersion Process Polyester Urethane Powder Coating (1.8 to 2.5 mils) NEXT GENERATION Zirconium First Generation Zirconium Average Pass/ Fail = 1000/ NA CURRENT PRETREATMENT Iron Phosphate with Chrome Average Pass/ Fail = 792/ 852 INDUSTRY STANDARD B-1000 with Silane post treatment Average Pass/ Fail = 852/ 902 Average Pass/ Fail = 636/660

17 Green treatments in Application

18 Sealer Comparison Conventional Technologies Questionable environmental impact Molybdate Chromate Phosphate Proven performance Based on application need Comfort in the marketplace Wastewater Intensive Next Generation Technologies Reduced environmental impact Many non-heavy metal Silane-based Polymer based Improved performance Mapping of performance to need in application Growing comfort in the marketplace

19 Sealer Development Next generation sealers Application in the market for over 10 years Wide acceptance versus Chrome (Hex) Wide acceptance of Silanes Paint and application specificity Broad application sealers available Much improved impact on the environment Broader acceptance, availability Reduced cost

20 Non-Conventional Performance DIP Seal Technology Typical 3-Stage Cleaner/Coater Application Replacement with Cleaner (Stage 1) and Dry-In-Place Sealer (Stage 3) Outcome elimination of phosphate, equal performance

21 Green Sealers in Application

22 greening your washer is a reality! Green cleaners rinse stage 1 stage 2 stage 3 Zirconium and non-phosphate stage 4 rinse Non-phos, non-chrome seals stage 5

23 Compliance Driven Innovation Alternatives to conventional technologies are available today Effective, yet safer cleaning alternatives Without chelants, phosphates, ph extremes Non-phosphate pretreatment alternatives Non-chrome, non-metallic seals Green is cost effective! Reduce water, carbon foot print, labor and environmental impact
