Musou Black Paint
Branching off of our company’s goal of creating high-quality ultra-black products, we developed Musou Black Paint. It is a water-based acrylic paint that can absorb up to 99.4% of visible-light, making it the World’s Blackest Paint. Achieving an ultra-black coating has never been easier!
- Please note that this product contains trace levels of ethyl acrylate, 1,4 dioxane, ethylbenzene, and cumene. Ethyl acrylate (CAS No. 140-88-5) 1,4-dioxane (CAS No. 123-91-1), ethylbenzene (CAS No. 100-41-4) and cumene (CAS No. 98-82-8) are listed on the California Proposition 65 List as chemicals known to the State of California to cause cancer. The trace level of these ingredients in the product does not warrant warnings for the purpose of California Proposition 65. The other ingredients in this product are not listed on the California Proposition 65.
- Due to the properties of the powdery light-absorbing layer, the durability of the top coating is very low, so fading and peeling of the coating will occur even with light contact.
- The painted object may shrink and crack.
- Particle dust will be produced during the painting process, so please wear protective equipment such as eye goggles and a face mask.
- Musou Black does not suppress infrared reflections.
- Not recommended for outdoor or automotive uses.
Musou Black can easily be applied with a brush or an air-brush. In order to achieve the best result, we strongly recommend air-brushing. By repeatedly applying multiple thin layers of powder coatings with an air-brush, you can achieve an ultra-black coating that can absorb up to 99.4% of visible-light!
Please be sure to check out the "How-to-Paint" video below for tips and tricks for air-brushing Musou Black Paint!
Even when painted with a paint brush, Musou Black Paint maintains an industry-leading light absorption rate of 98.8%! Due to its lower viscosity compared to general acrylic paints, it is easy to achieve a non-reflective matte surface.

Under 1.5% reflectance across the entire visible spectrum
Typical black paints absorb roughly 94–98% of visible light, a reflectance of 2–6%. Musou Black Paint pushes that to 99.4% absorption (airbrush application), an order of magnitude tighter than ordinary matte black.
The chart below proves it with real measurement data: compared to a standard black paint (reference, around 4% reflectance), Musou Black Paint stays under 1.5% across the entire visible range (250–750nm), whether applied by brush or airbrush. Hover any point to read exact values, toggle series in the legend, or switch the Y-axis scale.

A truly neutral black that never casts a color tint, in any lighting environment.
With no variation in reflectance by wavelength, subjects retain their true color under any light source, a difference that can take the finished piece to a whole new level.

Three reasons Musou Black Paint stands alone
200x magnification
3D surface analysis
A beautifully ultra-matte finish that traps light
The secret to Musou Black Paint's darkness lies in a microscopic surface structure formed in the cured coating. This structure scatters light internally, again and again, without letting it escape, producing an "ultra-matte" texture that conventional paints simply cannot achieve.
Turns a model into something otherworldly
Musou Black Paint forms a smooth coating whether applied with an airbrush or a brush. Its overwhelming black erases the texture of plastic entirely, giving the surface an unreal presence, as if it were CG, or a shadow made solid.
Your collection stops being "objects" and becomes art that captures the viewer's imagination.

FAQ
What is the heat resistance of this product?+
The heat resistance of this product is up to 80°C. Discoloration may occur above 80°C, so please take care with storage location and operating environment.
What's the biggest difference from ordinary matte paints?+
Standard matte paints create their "matte" effect by scattering light diffusely. Musou Black Paint instead traps light inside a microscopic surface structure formed in the cured coating, achieving overwhelming light absorption. This produces a "true black" that ordinary matte paints cannot replicate.
How should I apply this paint?+
We recommend airbrush application; no dilution is needed and it can be used as-is. If brush-applying, brush strokes may remain visible, applying several thin coats will make them less noticeable.
Does the finish differ between brush and airbrush application?+
Yes. Measured gloss at a steep 85° viewing angle is 3.3% for brush application versus just 0.10% for airbrush, airbrush produces the flattest, darkest finish, while brush application is slightly glossier at grazing angles. Both stay effectively glare-free (0.00–0.17%) at 20° and 60°.
Will this paint work on any material?+
It adheres well to most absorbent surfaces, including standard model plastics. Non-absorbent materials (such as glass or bare metal) may need surface preparation or a primer first for reliable adhesion.
Is Musou Black Paint water resistant?+
No. The cured coating has no water resistance, so it should not be used in wet environments or where it will be exposed to moisture.
Can I touch the surface once it's dry?+
We recommend against it. The cured coating is very delicate, even light contact can generate particles and damage the light-trapping surface structure. Reserve it for surfaces that won't be handled, and avoid touching it directly.
What safety precautions should I take when applying it?+
Wear a mask, gloves, and eye protection while applying, and avoid skin contact where possible. Refer to the Safety Data Sheet (SDS) for full handling details.
Is this paint suitable for infrared or LiDAR applications?+
Not ideally. Reflectance stays under 1% through the visible range but climbs to 2.0% at 950nm and 10.7% at 1500nm, so it isn't built for broadband near-infrared suppression. For NIR-heavy applications like LiDAR or infrared sensors, our FINESHUT series and IR Flock Sheet are the better fit, both hold flat, ultra-low reflectance from visible light through 1500nm, with IR Flock Sheet staying under 0.5% all the way out to 2500nm.
Can I paint my car with Musou Black Paint?+
We don't recommend it for everyday automotive use. You may have seen media coverage of a Porsche 911 Turbo finished in Musou Black Paint, that was a temporary application for a photo shoot and exhibition display, not a durable daily-driver coating. The cured film has no water resistance and very limited contact durability, so dust and water spots will visibly degrade the black over time on a car used outdoors.
Which size should I choose?+
100mL suits a single small model or test piece, and covers approximately 0.9 square meters by brush, single-coat. The 100mL × 20-bottle set is convenient for workshops, classes, or stocking up at a lower per-bottle cost. 1L covers larger models, multiple projects, or small studio use. 15L is intended for professional, industrial, or high-volume applications.
