Musou BLACK product guide

(click to enlarge) 

We offer ultra-black products in a variety of materials for a range of applications. This guide is to help you choose the right black for you if you aren’t sure which would be best for your needs. Their current product offerings can be divided by material type - polyurethane foam sheets, nylon/rayon fabrics, and a water-based acrylic paint. All products are RoHS and REACH certified - safe and non-toxic.

* When viewed by the naked eye, each person's perception of "blackness" may differ depending on the lighting environment and other conditions. 

Total reflectance values of our materials are based on the industry-standard AOI 8° index. Total reflectance is the measurement result of combining both diffuse reflection and specular reflection measurements. AOI 8° means that the light is incident at an angle of 8° from the normal. 

For example, based on this index, our "Foam" series consistently absorbs light from ultraviolet to near-infrared light ranges. This performance is achieved by the uneven structure derived from the foaming process and the composition of carbon atoms blended into the resin. 

We also offer a variety of fabrics. Our entry-level “VL Flock Sheet” is cost-effective and provides strong light-absorption performance in the visible light range. In contrast, our “IR Flock Sheet” provides improved ultraviolet and excellent infrared light-absorption performance, which are the weak points of the entry-level VL Flock Sheet. Our premium fabrics, Musou Black Fabric FR and Musou Black Fabric KIWAMI, are our blackest products and have the best visible-light absorbing performances. The FR variant is treated to be fire-resistant and is great for indoor use. Meanwhile, our flagship, Musou Black Fabric KIWAMI, is the World’s Blackest Fabric in the visible-light range. 

Musou Black Paint's light-absorption performance will vary depending on the painting method, so please keep that in mind when applying. For best results, please apply with an air-brush.
