Lamion™(Ultra-thin Glass Laminated on Resin)


Glass and resin combine to make
Lamion incredibly light

Technological advances in a wide range of fields have sparked new uses for glass.
Glass has useful properties not found in other materials, such as high transparency, strong heat-resistance, electrical resistivity, and impermeability to water and air. Its growing usefulness stems from its ability to improve product performance and enable new technological developments by using it as a replacement for other materials. Its one unfortunate drawback was its relatively heavy weight compared to materials such as resins.
We have solved this problem with Lamion, a hybrid material combining the advantages of both glass and resin. Lamion is the product of our wealth of expertise and technologies hard won through long experience of developing a range of radical products such as G-Leaf, the ultra-thin glass under 200 μm thick.

Lamion is a glass-resin bond enabled by our proprietary technology

Lamion is a laminated material, in which resin boards (polycarbonate or acrylic) or resin film (PET or PEN) are coated on one or both sides with G-Leaf via an adhesive agent.
It is quite difficult to bond different materials like glass and resin without allowing bubbles or foreign matter. But thanks to our proprietary technology, we have done so and fashioned Lamion to prevent peeling and turbidity in a wide range of environments, such as high temperatures and high humidity.
With this technology we have succeeded in making Lamion approximately 30% to 50% lighter than conventional glass of equal thickness. Furthermore, because Lamion’s glass-like properties make it resistant to scratches, shock, and discoloration, it is garnering attention as a new material in areas where resins alone have failed to do the job.

Lamion is light, plus resistant to scratches, shocks and discoloration

Because it possesses the advantages of both glass and resin, Lamion comes with an assortment of features never before seen in glass.
One is shock-resistance. The glass in Lamion is less likely to crack from impact because the resin absorbs the shock. And even if the glass does crack, the bonded structure formed by the adhesive agent keeps the damage confined to the point of impact. In addition, since Lamion has the acoustic properties of both glass and resin, it insulates sound better than glass alone would. And there are so many more benefits that make Lamion an appealing choice: the scratch-resistance of glass, high impermeability to gases like steam and air, no discoloration from ultraviolet light, electrical resistivity, better stiffness than resin of equal thickness…and more!

Lamion’s shock resistance and stopping ability are so good you can drop a 130-gram steel ball on it from two meters up and still it will not shatter.

Exploring new glass applications and possibilities with Lamion

From the everyday to cutting-edge tech, Lamion has the potential for uses in a wide range of applications and as a material for developing new technologies.
For example, Lamion’s light weight, scratch-resistance, and ability to confine cracks make it the perfect cover for outdoor digital signage. Meanwhile, its impermeability to steam and air make it a suitable material for OLEDs. Some are considering using resins in windows to lower the overall weight of rolling stock, aircraft and buildings, but Lamion offers the same light weight as well as other great benefits including resistance to scratches and discoloration.
You can also combine Lamion with our proprietary coating processes, such as anti-reflection (AR), anti-glare (AG), and anti-fingerprint (AF) coats. A showcase or painting cover with an AR-coated Lamion sheet on top creates almost no reflections while offering a realistic and highly appealing look at the product or panting. Lamion opens up the future potential of glass applications; for example, it is suited as a solar cell cover or for use on a sign with lightweight, gorgeous backlight.
We will continue contributing to building a richer future by developing technologies to deliver the advantages of glass to our everyday lives, society and industry.
