Technology Overview

Summers are cool
Winter is warm
Reduction in Energy Consumption
High Thermal Insulation
World's Highest Coating Porosity
Thanks to its unique blend of large hollow beads, it delivers exceptional thermal insulation.
It boasts the world’s highest void ratio among thermal insulation paints.
High Heat Resistance
Reflectance of 85% or higher
Thanks to the properties of special titanium dioxide, the material reflects more than 85% of visible light.
It reflects near-infrared rays, making it harder for heat to transfer into the building.
Heat Retention
Contains at least 50% hollow beads
Insulating paints, which take advantage of air's low thermal conductivity, vary significantly in performance depending on their hollow bead content and are effective at maintaining indoor temperatures.
Highly Stretchable
A coating that won't crack even when bent
Made from a material that can stretch by more than 200 percent, it prevents cracks caused by building vibrations and allows for painting on tents and fabrics.
High Durability
Can be used for more than 15 years
Weathering tests conducted by the Japan Paint Inspection Association have confirmed that the paint film shows no abnormalities (such as cracking, blistering, or peeling) even after more than 15 years of use.
It provides long-term protection for buildings and prevents deterioration caused by heat and ultraviolet rays.
High Adhesion
More than three times the JIS standard
Its strong adhesive strength has been verified through testing in accordance with Japanese Industrial Standards (JIS).
It can be applied to inorganic materials such as glass.
*A colorless, transparent version is not available.
Waterproof
Zero water permeability, but breathable
Since it is impermeable, it can be used to prevent water leaks and rain seepage.
It allows moisture to pass through, preventing stuffiness and creating a comfortable indoor environment.
It also prevents paint from blistering.
Anti-condensation
Accumulation of Radiant Heat Effect
The insulating effect helps prevent condensation caused by the temperature difference between the exterior and interior.
As a secondary benefit, it also helps prevent mold growth.
Soundproofing
Sound insulation effect of approximately 10 dB
Thanks to the properties of the coating, it reduces sound leaking from the rafters and walls, as well as incoming noise and the sound of rain.
Safety
Low environmental impact
F☆☆☆☆ certified.
Emissions of formaldehyde, a harmful substance, are essentially zero.
This paint is gentle on both the environment and your body.

How Insulation Works

By incorporating hollow beads, a porous layer is formed within the coating film.
By taking advantage of the low thermal conductivity of the space,
It achieves a "thermal insulation rate" that could not be achieved with conventional paints.

Awards, Registrations, and Test Evidence

SIAA

Certified by the Society for Antimicrobial Product Technology (SIAA)

Recognized for its antibacterial and mold-resistant properties,

it has been certified by SIAA.

Our “Legendary” is

the only paint registered with SIAA.

By applying this paint in areas where you want to prevent bacterial growth,

it helps create a “safe and secure space.”

熱伝導率測定

Thermal Conductivity Measurement

To demonstrate a thermal conductivity comparable to that of insulation materials,

we conducted tests through a third-party organization.

With a 0.4 mm-thick coating,

the thermal conductivity was 0.05 W/(m·K).

This figure proves that the product’s performance

is on par with that of standard insulation materials.

NETIS

Certified by the Ministry of Land, Infrastructure, Transport and Tourism’s New Technology Information System (NETIS)

Thanks to its NETIS registration,

it can also be used in the construction of public facilities.

Simply by applying a coat of paint,

it provides a building structure that is heat-resistant,

much like a simulated exterior insulation system.

耐候試験1500時間

1,500-hour weathering test

Because the coating film is

resistant to degradation caused by heat and ultraviolet rays,

it has demonstrated high durability in weathering tests.

This coating can be applied to fabric,

delivering a highly durable finish that does not crack.

Please note that these tests are still ongoing.
