The Vantablack coating for satellite constellations is engineered to dramatically reduce the visual signature of satellites, an essential feature for many space missions. With a total hemispherical reflectance of just 2% and high ATOX resistance, this coating is designed to maintain satellite performance even in the harsh conditions of space. Its lightweight nature, with a coating mass of less than 5mg/cm² at 30µm thickness, ensures it adds minimal weight to the spacecraft.
One of the standout features of this formulation is its high emissivity (greater than 0.98), which stands out in the space industry for its efficacy in thermal management. This property is crucial for regulating the temperature of sensitive satellite components, thereby enhancing the reliability and longevity of the spacecraft.
Moreover, the Vantablack satellite coating is praised for its ultra-low outgassing properties, conforming to ASTM E595 standards, which are critical for maintaining optical and instrument integrity over the satellite's operational lifespan. Its reliability across extreme temperatures, from -196°C to 200°C, further underscores its suitability for a variety of space missions.
