Typical grades
Bio-ethanol
Biodiesel
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.
100% bio based fuels
• 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)
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
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

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

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.
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.

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
• …
