Waterborne paint has no risk of fire, has high hygiene safety because dilution thinner is unnecessary. In general, waterborne paint has poor weather resistance and poor adhesion, and they agglomerate when emulsified. Furthermore, since the molecules of the coating material are not uniformly dispersed but are biased, it is necessary to inject additives such as a dispersing agent. And as particles become smaller, they tend to agglomerate, making dispersibility very difficult. However, we succeeded in experiments and obtained a patent based on the concept of supercriticality, making a device to enhance dispersibility. It exceeds the concept of conventional aqueous paint and has excellent features.
The technology of NanoMighty can nanolize aqueous paint and can maintain nano state. (Patent 4568792)


In general, matter is in a state of solid, liquid and gas. A supercritical fluid is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist. It can effuse through solids like a gas, and dissolve materials like a liquid. In the case of water, it is called as super critical water.

NanoMighty is a novel paint developed using supercritical technology.

Type of waterborne paint

Water-based acrylic
It is called acrylic resin paint. The basic component is resin and it is an acrylic paint. Because it has excellent adhesion, it is often used for housing in Japan. The price is reasonable, but its useful life is short.

Water-based urethane
The resin which is the basic component is urethane type. It has excellent adhesion and weather resistance. Since it is completely water-based finish, low odor, low pollution.

Water-based silicon
The resin which is the basic component is silicon type. It is heat resistant and durable.

Water-based acrylic and silicon
It is a paint that combines the durability of silicon and the adhesion of acrylic.

Although NanoMighty is an aqueous acrylic type, it’s durability and weatherability equals to or higher than that of the aqueous silicon type.

Principle of NanoMighty

Particle size distribution of Commercial general paint
(Scattering type particle size distribution measuring device)

Since particle size is big, contact point is small, adhesion is weak and deterioration is fast.
NanoMighty is born when commercial general paint is processed with our company's technology.

Particle size distribution of NanoMighty
(Scattering type particle size distribution measuring device)

Since particle size is small, there are many contact points, strong adhesive force and slow deterioration.

Common paint molecules -> Coating material surface

Insulation and strong against sun and heat

NanoMight is excellent in heat resistance. As it approaches fire, it will carbonize, but it will not burn easily. Despite the ultra-thin waterproof layer, it is resistant to fire and heat,so it is particularly ideal as a waterproof material for floors and roofs.
Since NanoMightt also has high insulation (with a coating of 2 mm, can withstand 12000 volts) performance, it is used as a roof waterproof material for railway vehicles.
