Tech Info / HIREC® Shows High Durability in Temperature with Humidity Cycle Test
HIREC®: Super Hydrophobic Coating for Antenna, Radome and Other Public Infrastructure
Temperature with Humidity Cycle Test
The change of the contact angle of a HIREC® coated surface was measured in Temperature with Humidity Cycle Test. The test was done for temperature range from -30°C to 70°C, humidity up to 90% R.H., 12 hours/cycle, and 100 cycles. The test result showed the HIREC® has a stable performance in the temperature with humidity cycle test and has high durability.
Measurement: Contact angle (degree)
Cycle time: 12 hours per one cycle
Duration: 100 cycles
Temperature change: 20°C - 70°C - -30°C
Humidity change: 90% R.H. at 70°C, 50% R.H. at 20°C
Test Results of Contact Angle Change in Temperature with Humidity Test
HIREC® shows no abnormality during 100 cycles in the temperature with humidity cycle test
Initial contact angle of HIREC® was 152°.
HIREC® maintains highly durable super water repellency in the temperature with humidity test.
