Corrosion resistance test. The test
was performed on a bright red panel. This test provides a controlled
corrosive environment which produces relative corrosion resistance
information. The salt spray (fog) duration was 1000 hours. |
Light blistering, no peeling. |

- Crosshatch adhesion test.
- A lattice pattern with either six or eleven cuts in each
direction is made in the film to the substrate. Then pressure-sensitive
tape is applied over the lattice and removed. Adhesion is assessed
qualitatively on the 0 to 5 scale.
|
Result: Rating of 5. This is the
best rating that can be obtained using this method. |

- Humidity -Thermal cycle cracking test.
- This test method provides an accelerated means of determining
the tendency of a coating to fail by cracking when exposed to
humidity-thermal cycling. The samples were tested for 10 hot
and cold cycles (-23° C to 38° C) at 100% relative humidity.
|
No cracking.
No blistering.
Very good gloss retention.

- Accelerated weathering test / xenon arc. Both these tests
consist of a cyclical test of wet conditions, dry conditions
and ultraviolet exposure designed to represent exposure to variable
realistic climate conditions. The test samples were exposed for
1000 hours.
|
No blistering.
No peeling.
Very good gloss retention.

- Abrassion resistance, Taber Abraser method.
- Abrassion resistance is calculated as loss in weight at a
specified number of abrasions cycles, as loss in weight per cycle,
or as number of cycles required to remove a unit amount of coating
thickness. Test samples were suject to 100 cycles of 1000g load
on CS-17 abrassive wheels.
|
Average loss 0.017g. at 100 cycles. |

- Bending test.
- The coated samples are bent over a mandrel and the resistance
to cracking of the coating is determined (from 0° to 135°
).
|
No cracks @ 135°.
No peeling @ 135°.

- Water vapor transmission of coating.
- This test determines the rate of water vapor transmission
(WVT) of the coating, through which the passage of water vapor
is important in applications such as concrete and masonry surfaces.
|
9.4 perm (inch-pound) or 5.37 x 10-7
g/pa*s*m2 considered a good value for a breathable coating. |

- Resistance to atmospheric & acid pollutants.
- This test determines the effect of household chemicals on
coated surfaces resulting in alterations in the surface, such
as discoloration, change in gloss, blistering, softening, swelling,
loss of adhesion, or other changes.
- Chemicals tested:
- Ethyl Alcohol 59% volume
- Acetic Acid 10% volume
- Hydrochloric Acid 5% volume
- Soap Solution 5% volume
- Detergent Solution 5% volume
- Oils, Fat, Lubricating grease, Coffee and Organic solvent (pentane).
|
No noticeable effect.
