1 Latest Generation Epoxy Novalac Solvent Free Coatings for the biofuel market

2 Content of the presentation The tendencies in the petrochemical land storage market Difference between bio-ethanol types and biodiesels based on FAME Difference in the impact on the land storage coatings The answer from the coating manufacturers Chemical background of the new technologies used Outlook for the future

3 Tendencies in the petrochemical land storage market Motor gasoline mix Biofuel 3% Biofuel 6% Motor Gasoline 97% Motor Gasoline 94%

4 Tendencies in the petrochemical land storage market Biofuel mix Biodiesel 19% 2007 Fuel ethanol 81%

5 Tendencies in the petrochemical land storage market Hydro-carbon Bio-Fuel mixtures BIO Fuels Petrol Bio fuel Diesel Bio fuel 100 % BIO based Ethanol Vegetable oils Palm oil fatty acids Bio gas

6 Difference between bio-ethanol and biodiesels based on FAME Biofuel Biofuel Bio-ethanol Biodiesel Typical grades E5: 5 % blend of ethanol in gasoline E10: 10 % blend of ethanol in gasoline B5: 5 % blend of FAME in diesel B20: 10 % blend of FAME in diesel Biofuel is considered an important mean of reducing greenhouse gas emissions and increasing energy security. Biodiesel is produced from any fat or oil such as soybean oil, rape seed oil and palm oil. Typical grades are biodiesel B5 (blend of 5 % fatty acid methyl ester (FAME) and conventional petroleum diesel.

7 100% bio based fuels Ethanol made from Sugar cane Grain Corn C 2 H 5 OH

8 100% bio based fuels Bio Diesel made from vegetable oil Rape seed Palm oil and other vegetable oils FAME (fatty acid methyl ester)

9 Impact on the tankcoatings used The impact of bio-ethanol and FAME is different! Most existing tank coatings based on standard epoxy technology are also resistant to FAME Most existing tank coatings based on standard epoxy technology are also resistant to E5 BUT : ethanol/fuel mixtures of >5% are problematic! Many failures of coating systems are to be expected in the coming years The impact on this on the protective coatings market should not be underestimated

10 The answer from the coating manufacturors Market requirements Tank owners require the next generation solvent free phenolic epoxy tank linings that are resistant to latest gasoline blends from E5 to E100 and biodiesel. Increasing high temperature resistance to crude oil. PPG PMC has listened to the market and elaborated their epoxy novolac technology

11 Chemical background of the new technologies used Standard epoxy (tank) technology is based on 2-dimensional polymers : A A B B A AB B A (F=2) B (F=2) => chain lengthening Epoxy novolac tank coating technology is based on 3- dimensional polymers A A B B A AB B A B B A (F=3) B (F=2) => crosslinking A B B

12 Novolac epoxy: Chemical background of the new technologies used O O O HC CH 2 HC CH 2 HC CH 2 CH 2 CH 2 O CH 2 O O CH 2 CH 2 n (F>2)

13 Chemical background of the new technologies used Classical solvent based novolac epoxy: F > 3 Example : Phenguard series New solvent based novolac epoxies: F = /- 2,5 Example : Novaguard series The classical solvent based novolac epoxies are generaly resistant to ethanol (with additional curing requirements) PPG has further developed the solvent free range and has now a product resistant to ethanol without additional curing requirements

14 Application Area Typical chemical resistance chart Biodiesel B5 Biodiesel B10 Biodiesel B100 (FAME) Crude naphtha Crude oil Gas condensate Gasoline E5 Gasoline E10 Gasoline E20 Gasoline E85 Heavy fuel oil Jet fuel Unleaded gasoline Standard Sigma NovaGuard Epoxy Novalac 840, 90 C, note , 90 C, note 2 Sigma New Epoxy NovaGuard Novalac 890, 90 C, note 2, 90 C, note 2

15 Features & Benefits (1) Can be applied with standard airless equipment (no hot twin feed application) No limitation to the amount of (bio)ethanol present gasoline blends to provide maximum storage flexibility of today s tank terminals. No hot cure required when gasoline blends with ethanol are stored, maximum application flexibility. Wide chemical resistance to crude oil up to 90 C, unleaded gasoline s, and biofuels. One-coat system directly to steel, no primer required, reducing down time.

16 Features & Benefits (2) Drying down to 5 C creating maximum application window flexibility and reducing turnaround times. Good filling properties making it an excellent choice for refurbishment of pitted tanks. Can be reinforced by chopped fiber or glass laminates, which makes it full package coating for tank maintenance. Light colour improves the application and inspection characteristics. The smooth and glossy appearance, easy to clean. Solvent free, improving working safety.

17 Specification Typical specification Standard New Solvent Free Epoxy Novalac, 400 μm Large tanks when holding primer is required Epoxy Novalac holding primer, 75 μm New Solvent Free Epoxy Novalac, 400 μm

18 Outlook to the future Based on this new technology, PPG seeks to further improve/complete the product range : Conductive version for certain regions where this is required Quicker drying products
