What should I consider before I choose MaxiBlack™?

When choosing the appropriate and accurate coating for your needs, you must consider the three main factors: spectral range, substrate materials, and environmental compatibility.

Spectral Range: extreme UV to far IR wavelength.
Substrate Materials: MaxiBlack™ is available on various substrates, including aluminum, stainless steel, and polyimide films.
Environmental Compatibility: MaxiBlack™ performs well under extreme conditions such as:
- Vacuum environments
- High temperatures (-196°C to +350°C)
- High humidity
- Cleanroom conditions

Main characteristics

Light Absorption: exhibits exceptionally low reflectance, achieving a specular absorptance of 99.9%. Consequently, it effectively absorbs stray light and reduces unwanted reflections.

Flexibility: Its adaptable structure enables it to adjust to different shapes without sustaining damage.
Thinness: consists of a polymer film that typically measures 50 to 80 microns in thickness, with a coating layer of 3 to 5 microns, enabling it to conveniently conform to complex assemblies and uneven surfaces.
Low Outgassing: This material emits very few gases, making it suitable for vacuum or cleanroom settings.
Thermal Stability: maintains its performance across a broad temperature spectrum. It withstands long-term exposure without adhesive from -196 °C to +350 °C and can handle short-term exposure of up to +400 °C.
Wide Spectral Range: It remains effective from extreme UV to far IR wavelengths.

MaxiBlack™ features a distinctive design and composition that performs well in various industries. Its durability against extreme conditions and superior light absorption properties are essential for space exploration, automotive advancement, semiconductor accuracy, and beyond.
