High emissivity coating

Introduction of radiating coating product

High-emissivity infrared ceramic radiation heat dissipation coating is a two-component high-emissivity infrared radiation ceramic coating. It uses the high thermal conductivity and high emissivity of infrared ceramics to transfer the surface heat of high-temperature devices into the coating and use infrared The method radiates to the outside world, accelerates the heat exchange between the device and the outside world, reduces the surface and internal temperature of the device, so as to achieve the effect of improving the stability and service life of the device.

Main performance

(1) High infrared emissivity: The emissivity of the coating in the infrared (2-25 μm) band is 0.86-0.92, with small temperature dependence;
(2) Excellent radiation heat dissipation performance;
(3) Excellent aging resistance;
(4) Excellent thermal conductivity;
(5) Excellent mechanical properties and salt spray resistance;
(6) Excellent construction performance.

Infrared radiation rate of coating at 800℃ (3~5 microns)
Ultra-high temperature radiation cooling

Blank AI substrate plate(Burn through time)=30s Coated Infrared substrate plate(Burn through time)=210s
The burn-through time is extended by 7 times! → The radiation cooling effect is remarkable!

Lower temperature radiation cooling

Lower temperature radiation cooling test device               cooling curve In 600g 85℃ water 22min
Increase in cooling rate: 13%
Cooling temperature difference: 3.5℃
