Polyglass Ecoflake

Product reference: 2/36

Product title: Ecoflake

Valid from: 7th December 2004

Last reviewed: May 2019

Type: Styrene free bisphenol polyester glass flake. 

Suggested use

Applications where styrene is not desirable or allowed.
Immersion: Marine, including splash zones, hydrocarbon
storage,aqueous, corrosive chemical environments, etc.For
Chemical resistance data refer to the Corrocoat Chemical
Resistance list for Corroglass 200Series.
Non-immersed: Aggressive atmospheric conditions and
corrosive gas, superstructures, Heli-decks, structural
steel work etc. Polyglass Ecoflake has good UV
resistance and good flexibility at dry film thicknesses of
less than 1.25 mm


Limited protection against polar solvents, not suitable for demineralised water or where pH conditions are <1 or >12.

Health & safety

Before handling or using this product, the material safety
data sheet should be read, and all precautions observed

Surface preparation

Metals: Grit blast to SSPC-SP10 (ISO standard 8501-1 Sa
2½) (Forfull details referto CorrocoatSurfacePreparation
Concrete: refer to Corrocoat data sheet SP5

Recommended DFT

24-32 mils (600 – 800 microns) in atmospheric conditions.
34-48 mils (850 – 1250 microns) in aqueous and
marine immersion. 48+ mils (1250 microns) plus in
highly corrosive conditions and chemical service.
This material is a barrier coating and the thickness needed is
dependent upon service conditions. If in doubt seek guidance.

Pot life

Varies with temperaturebut approximately50 minutes at 68°F
(20°C). Pot life extender (retarder)available, refer Corrocoat

Practical spreading rate

42 sf per gal at 30 mils (1.05m2
/litre at 750 microns).
NOTE: This information is given in good faith, but rate
may vary significantly dependent upon environmental
conditions, the geometry and nature of work undertaken
and the skill and care of application. Corrocoat accepts
no responsibility for any deviation from these values

Specific gravity

Base & Hardener Mixed sg:1.15 gms/cc.

Pot life

Varies with temperaturebut approximately50 minutes at 68°F
(20°C). Pot life extender (retarder)available, refer Corrocoat

Elongation at break

Atmospheric conditions 1.3%.

Tensile strength

3900psi (274 kg/cm²) dependent upon cure state.

Temperature limits

194°F (90°C) immersed
266°F (130°C) non immersed, dependent upon service.

Abrasion resistance

255mg. Loss 1000 cycles/1000 gm load H18 wheel.

Mixing ratio

100:2 base to hardener.Mix well using a mechanical stirrer.

Application equipment

Airless pump 45:1 or greater, fit leather and PTFE seal
combination and remove all fluid filters. 10mm diameter (3/8”)
nylon lined hose with whip end. Large bore gun with
24 to 60 thou reverse clean tip. Typical tip size is
30-35 thou with a 45° fan pattern. Size of tip and fan pattern
will vary with nature of the work. Pressure to suit hose length
and working conditions (circa 200bar).(Use Vinyl Toluene
as the priming fluid).


Dependent upon intended use and site conditions, but
Ecoflake is normally applied wet on wet at films between
20-40 mils (500-1000 microns). For further details see
Polyglass Application Data Sheet 6/20 ABC. Single coat
application is acceptable.


This product should not be thinned. Under no
circumstance should solvent be added to this material.


1 Gallon and 5 Gallon kits, including hardener

Storage life

Base 12 months, Catalyst 6 months, stored at temperatures
below 68°F (20°C) and out of direct sunlight. Frequent
temperature cycling will shorten storage life and may cause
lump formation. It is recommended during extended
storage, i.e. greater than 3 months, that the drums be
periodically inverted.

Color availability

Off white as standard. Green, yellow,grey,red oxide and black
to order, subject to minimum order quantities of 265 gallons
(1000 litres).

Theoretical spreading rate

54 sf per gal at 30 mils (1.33m²/litre at 750 microns).

Volume solids

This coating contains volatile liquid convertible to solids.
Actual volume solids obtained will vary dependent upon
polymerization conditions. Nominally 97% of the contents are
convertible to solid.

Flash point

133°F (56°C).

Catalyst type

Methyl Ethyl Ketone Peroxide type P2


Greater than 40 Barcol after full cure.


May take place as soon as the previous coat has gelled and
while still tacky. Maximum overcoating time is 72 hours at
68°F (20°C). For times in excess of 72 hours and for
coating of concretesubstrates,referto Corrocoatfor special

Curing time

With standard inhibitor level, tack-free 6 hours, full cure 3-4
days at 68°F (20°C) but may be immersed in many
environments after 8 hours. Excellent low temperature curing

Cleaning solvent

Methyl Ethyl Ketone, Methyl Iso Butyl Ketone – before gel.
