Tendencies in the petrochemical land storage market
Biofuel Typical grades
Biofuel Bio-ethanol
Biodiesel
E5: 5 % blend of ethanol in gasolineE10: 10 % blend of ethanol in gasoline
B5: 5 % blend of FAME in dieselB20: 10 % blend of FAME in diesel
Biofuel is considered an important mean of reducing greenhousegas 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.
Difference between bio-ethanol and biodiesels based on FAME
• Ethanol made from– Sugar cane– Grain– Corn
C2H5OH
100% bio based fuels
Bio Diesel made from vegetable oil
– Rape seed– Palm oil– and other vegetable oils
FAME (fatty acid methyl ester)
100% bio based fuels
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 inthe coming years
• The impact on this on the protective coatings market should not be underestimated
Impact on the tankcoatings used
Market requirements
• Tank owners require the next generation solvent free phenolicepoxy tank liningsthat are resistant to latest gasoline blends from E5 to E100 and biodiesel.
• Increasing high temperature resistanceto crude oil.
PPG PMC has listened to the market and elaborated their epoxy novolac technology

A (F=2) + B (F=2) => chain lengthening
Standard epoxy (tank) technology is based on 2-dimensional polymers :
Epoxy novolac tank coating technology is based on 3-dimensional polymers

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

New Epoxy NovalacStandard Epoxy Novalac
• 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.
Features & Benefits (1)
• 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.
