The Musou Black Paint Absorbs 99.4% of Visible Light!

The Musou Black Paint Absorbs 99.4% of Visible Light!

January 27, 2021

Musou Black is a new scientific paint that can absorb almost all visible light. It has crazy potential for extreme research purposes.

High school science has taught us about black bodies and the wonders of space- the black holes. These have been called the darkest objects in the universe, and black holes go one step further by virtually absorbing 100% of visible light.

Neither of these is a human-made creation, but we’ve been working pretty hard to mimic those properties, and Koyo Japan may finally have made the leap.

Previous Competitors

Before Koyo Orient Japan introduced Musou Black to the world, we did have “black paints” competing to be the most absorbent pigment out there. The two main frontrunners were Black 3.0 and Singularity V3.

The exciting thing about these two is that Black 3.0 is solely available as a paint, and Singularity V3 is exclusively available as a material. While Black 3.0 is a pigment/paint, Singularity V3 is a nano-material based object. The material has a nanofiber array which absorbs all light that bounces on it, barely reflecting anything.

There is one more name, though. Vantablack. This is the boss of the whole “blackest black” competition and is so powerful that you literally need a license to own it! The general population isn’t even allowed to purchase Vantablack.

Just like Singularity V3, Vantablack is also a nanomaterial-based black colour and is the most absorbent of all products. Think of it as the dark matter of human-made objects!

Musou Black - Almost a Black Hole

The latest entry in this sector is Musou Black. Developed as a powdery substance and as a paint, the acrylic pigment claims to absorb more than 99.4% visible light. This is by no means the highest absorption percentage amongst its peers, but it is commendable nonetheless.

The pain can be brushed on any surface or even sprayed using an airbrush. The company claims that Musou Black is best used with an airbrush and the difference is noticeable. However, the paint does create a skinny layer on a surface with an even thinner absorption layer and can rip or peel easily. So, don’t go painting your cars just yet hoping to turn them into Batmobiles!

If having the paint version of Musou Black wasn’t enough, Koyo Japan has also unveiled their very own Musou Black Fabric! It is a Visible Light Absorbing Flock Sheet and looks and feels very much like cloth. The cloth displays the same absorbing quality as Musou Black paint and is very foldable, a desired trait in fabrics if you didn’t know.

What Can We Do with It?

So, what have we achieved after creating these “blacker than black” products? Indeed, the world doesn’t need such a shade of black for, let’s say, their hair colour, right? Regardless of how comical it looks, it is not easy to get your hands on these products.

Firstly, they are limited in stock and super expensive. Secondly, they can pose a severe threat if it ends up in the wrong hands. The most utilised product right now is Vantablack. Coincidentally (or not), Vantablack is the only non-commercial product on this list.

Majority of the work occurs in aerospace and defence with instruments the most prominent applications. These high-absorption materials/pigments are used to coat the inside of telescopes to eliminate light contamination and around lenses and sensors to improve data mining accuracy.

Last year, BMW made headlines with its ‘Vantablack’ X6, which was capable of absorbing 99.965 per cent of all light that falls on it. This would make it the darkest object on the street, if it were to be seen on the streets.

Defence Research

Defence organisations use Vantablack and Singularity to create space equipment and research instruments using these reliable material blocks to make parts. The paints, however, have a different design approach.

Scientists are using the pigments to recreate chambers mimicking deep space to understand how light travels and how it interacts with celestial objects. It is now possible to create our Solar System with a 99.5% accuracy of light behaviour.

Vantablack
Vantablack still holds the title for being the blackest black in the world.

It is believed that understanding how these materials and paints work and can be improved will achieve almost 100% absorption. This will ultimately lead us to explore the concept behind black holes, dark matter, black bodies and even stranger phenomena.  Anyhow, Musou Black IS commercially sold, so you have a good chance of getting it on your hands! Be creative but use it wisely!
