2.3 - Summary of problems with light-absorbing, high-temperature resistant coatings

Q: Is Naxion's light-absorbing, heat-resistant coating electrically conductive? #

Nash is currently available in two modelsHigh-temperature resistant light-absorbing coatingOne is a carbon based coating and the other is a metal oxide coating. It is non-conductive at both high and normal temperatures. Typically, insulation and non-conducting/heat-absorbing properties are correlated. With the exception of a few materials such as cubic boron nitride, they are basically non-conductive and at the same time non-conductive/heat absorbing.

Nasi light-absorbing coatings in the type of metal oxide film, insulation (mainly aluminum oxide) is better. Under the 200 megohm multimeter, it shows insulation.

Q: Have the parameters of Naxion's light-absorbing, high-temperature resistant coatings been tested? #

Yes. Nasi's light absorbing thermal insulation coatings have been developed with 2022 and are already available in two series. In cooperation with national research institutes, there are specialized light absorption tests, particle precipitation tests, and microhardness measurements. Insulation properties, we usually use a multimeter to estimate. In the early stage of the development of light-absorbing insulating coatings, a 150V 9S breakdown test was done, with a film thickness of 3 μm. The film thickness of PVD nano-coatings greatly affects the functional properties of the coatings. Although Ruoxi has not done the third party insulation test again, it is expected that with a film thickness of 8μm, the breakdown resistance will be greatly improved.

Q: Can I have the light-absorbing coating shipped to me to paint myself? #

No, we use the PVD vacuum coating process, not the water soluble nano paint/coating as the market says. We need to do physical weather deposition in a vacuum ambient oven, heated up to 150-650°C.
