Musou Black Paint

This is not CGI, this is Musou Black

Meet the ultra-low reflection paint "Musou Black"

Musou Black Gunpla

We are very excited to present a new product from Koyo Orient Japan, a water-based acrylic paint, "Musou Black".


Our super light absorbing material, "FineShut" are made in sheets so we faced some complications when attaching it onto 3D objects. Regardless of industry, there is a great need for an ultra-low light reflection treatment that can be applied onto 3D shapes. To fulfill that need and to make our first step into entertainment, we developed the "World's Blackest Acrylic Paint."


This water-based acrylic paint, "Musou Black" is a unique product. It has achieved a light absorption performance comparable to that of our FineShut series as a water-based paint and without the complications of FineShut.


This paint is darker than Black 3.0. Please feel free to take a look at our blog in regards to this: Black 3.0 vs Musou Black.


Our hope is that this black paint will bring inspiration to everyone.

A water-based acrylic paint with a total reflectance rate of 0.6% in the visible light range

Total visible light reflectance rate (AOI 8 °)

General black acrylic paint 2-6%

FineShut SP 1.2%

FineShut KIWAMI 0.8%

Koyo Flock Sheet 0.7%

Musou Black (airbrush) 0.6%

This water-based paint can be easily applied and it has achieved an overwhelming blackness that is comparable to FineShut KIWAMI and Koyo flock sheet. Airbrushing creates a powder coating on the surface of the target object, giving it a black appearance with ultra-low reflection.

Brush painting is also possible. Even if painted with a brush, this paint maintains the world's highest class low reflectance rate of 1.2%. It has a high concealment and low reflection performance, but has much lower viscosity than general acrylic paints, and it is easy to make a smooth non-reflective surface even with brush painting.

Product Specifications

Product Name: Musou Black

Product Type: Synthetic resin paint

Ingredients: synthetic resin (acrylic), pigment, antifungal agent, water

Applications: plastic models, various models, crafts, etc.

(A non-water-absorbent material may require a surface treatment or primer.)

Capacity: 100ml

Precautions for use

  • Due to the powdery light absorption layer, the strength of the coating is very low, so glossing and peeling of the coating will occur even with light contact. The painted object may shrink and crack.
  • Powder dust will be generated during painting, so wear protective equipment such as goggles and a mask before using.
  • This paint has no near-infrared reflection suppressing effect.
