Musou Black is an ultra-low reflectance black paint developed by Koyo Orient Japan, designed to be "the world's blackest black." Using advanced nano-level light absorption technology, Musou Black absorbs up to 99.4% of visible light—far beyond conventional black paints. Originally created for optical instruments and scientific applications, it has since become a favorite among artists, modelers, and photographers seeking a truly "absolute black" finish.

More than just a color, Musou Black embodies the Japanese spirit of craftsmanship and precision. Each bottle is carefully quality-controlled to ensure a smooth, non-reflective surface whether applied by brush or spray.

Musou Black is a water-based paint that absorbs 99.4% of visible light, far beyond the 94–98% typical of standard black paints.

Applied with an airbrush, it forms a powdery coating with a large surface area that traps light, resulting in an ultra-low reflectance of just 0.6%. Easy to use without special conditions, it delivers an exceptionally deep black finish.

📋Application Guidelines

  • 💨 Spray Application Method

    Recommended to use an airbrush to achieve the highest light absorption rate of 99.4%.

  • 📏 Nozzle Size

    Nozzle size above 0.5mm: Ready to use without dilution.

    Nozzle size below 0.5mm: Dilute with water to prevent clogging.

  • 🛠️Spray Technique Guide

    Apply in multiple thin layers, allowing a few minutes between coats—avoid heavy spraying.

  • 🖌️Brush Painting Guide

    Achieves approximately 98.8% light absorption.

    Use a flat, soft brush and apply multiple thin coats to avoid streaks and unwanted reflections.

  • 🚫 No Infrared Suppression

    Effective only within the visible spectrum.

  • ⚠️Precautions

    The coating is delicate and may fade or peel with contact.

    Surface cracking or shrinkage may occur after application.
