We are most likely to search for a materials research institute in zhejiang, light absorption can 99% above the super black coating, “the coating can be deposited on the surface of a variety of substrates, at the same time can realize the large area batch preparation, and can adapt to high temperature, low temperature, vacuum, liquid and other extreme service environment.” Unfortunately Lincy has not used them personally, but quite a few of my customers have approached them, and let’s just say the application working conditions are different. They describe their super black coating in terms of deposition and no weight gain, odds are it’s a vacuum coating process as well.

Lincy guesses that the coatings on the market are more oriented to decorative plating, so there will be a significant gap in high temperature resistance, abrasion resistance, bonding and more complex working conditions. Typically, decorative plating lacks a priming layer and has a distinct pick on the substrate.

There is also a nanotube technology that achieves the ultra-black light-absorbing coating effect. Inspired by this, assuming that this light-absorbing coating is plated on a femtosecond or microscopic corrosion surface, the absorbance should be significantly increased. Making microstructures of metal surfaces currently has very good applications in hydrophobic coatings, similar to the lotus leaf effect. Similarly, there should be a very good practical effect in the field of light absorption, which allows the light to go through multiple rounds of reflection and diffuse reflection, and cuts down the spillage significantly.

NaxauDEB coating is one of the few high-temperature oxidation-resistant light-absorbing coatings that has been mass-produced.

Yes. Currently has four types of customers and is in the use secrecy stage. Currently, it is mainly used in high-power lamps, medical nuclear magnetic equipment, mid-infrared absorption, and deep-space light absorption. In addition, this coating is a high-temperature-resistant insulation, which can be used in nuclear power, base station parts, and so on.

• Naxau DEB light-absorbing coating is a PVD vacuum coating process for incoming materials, where the workpiece is hang-plated in a vacuum furnace at 250-450°C, and PVD vacuum deposition is carried out.
• The price is calculated according to the amount of furnace. Usually 12,000-15,000 yuan a furnace; such as the largest size of the workpiece ≥ 800mm, plus 500 yuan outsourcing pre-treatment costs.
  If you have the opportunity to proof with the oven, it is free of charge.
• Currently, the maximum processing size is φ600x850mm, and for customers who do not require high light absorption and film thickness, the maximum size of the vacuum furnace can be expanded to φ680x1700mm.
• Specialized furnace, delivery time 2-3 days; sampling with the furnace, about 1 month due to irregular furnace opening.

It is possible that nano-alumina is a typical infrared absorbing material. Suitable porosity and surface roughness will further enhance the absorption effect. NANOXI light absorbing coating series, more importantly, has a certain wear resistance and high bonding force for industrial or special purposes, thus sacrificing part of the light absorbing absorption energy.
