Tech Info / HIREC® Shows High Durability in Water Immersion Test
HIREC®: Super Hydrophobic Coating for Antenna, Radome and Other Public Infrastructure
HIREC® - Water Immersion Test
The stability of HIREC® water repellency was measured by water immersion test. HIREC® coated aluminum plates were plunged into water 3 months and the change in contact angle was measured. The contact angle of HIREC® after 3 months water immersion was greater than 140 ° and showed durable water repellency.
Test sample:
|
HIREC® coated aluminum plate |
Measurement:
|
Contact angle (degree) |
Test liquid :
|
Distilled water |
Test temperature :
|
23 °C ± 2 °C |
Duration :
|
3 month (92 days) |
Measurement set-up :
|
|
The specimens were fully immersed in pure water having adequate amount.
After specified test time the specimens were taken from the test water. Then contact angle of the specimens were measured. Put the specimens back into the test water to continue the test.
Results of Water Immersion Test
 |
HIREC® shows no abnormality during 92 days or 3 month water immersion.
|
| |
Initial contact angle of HIREC® was 152°. |
| |
Contact angle during and after 3 month water immersion was greater than 140°. |
| |
The contact angle was stable during the water immersion test. |
 |
HIREC® maintains highly durable water resistance in 3 months water immersion test.
