オプトジャパン List of Products and Services

Opt Japan Co., Ltd. offers the "Photocatalytic Nano Guard AG Method." As part of the cleaning procedure, we first remove organic matter from the glass surface through hydrophilization treatment. After that, we apply a primer to the sash and seal areas, and finally, we apply a topcoat to the glass portion. Additionally, this technology can be used for photocatalytic coating not only on glass but also on sashes. 【Workflow】 1. Hydrophilization treatment: Polishing until water no longer beads 2. Primer: Apply two coats to the sash and seal areas 3. Topcoat: Apply 2 to 3 coats of the specified amount to the glass portion *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

At Opt Japan Co., Ltd., we offer the "Nano Guard AC Method," which can protect the surface layer. This technology penetrates cracks and forms crystals, enhancing the durability of concrete. Additionally, it can decompose rain stains and exhaust gas pollution, thereby improving the aesthetic quality of concrete. 【Features】 ■ Inorganic ■ Highly decomposable ■ Surface protection ■ Micro-repellent ■ Non-repellent *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

The Nano Guard series is a transparent heat-shielding coating agent, likened to a "transparent parasol." By reducing the film thickness and achieving high-density dispersion, it resolves conventional issues such as film thickness, transparency, leveling, and the risk of thermal cracking. It also enables clean application. To maintain a visible light transmittance (brightness) of 80-85%, it can be used in situations where the interior needs to be clearly visible from the outside, such as in show windows and stores. Additionally, it blocks approximately 50-60% of infrared (heat) rays (for transparent materials like glass and polycarbonate). <Features> ■ Material design considering practical application ■ Cuts infrared rays by up to 60% ■ 80% visible transmittance ■ Reduces air conditioning electricity usage ■ Seamless coating ■ Durability of over 10 years, etc. *There are also successful applications at Sapporo Dome. The coating division has received high evaluations for its material design considering practical application! *For more details, please refer to the PDF document or feel free to contact us.

The transparent heat-insulating coating agent for glass, Nano Guard ATO, cuts infrared rays from sunlight by 60-80% and ultraviolet rays by 97%. About 71% of summer heat enters through window glass. Approximately 48% of winter heat escapes through window glass. In summer, raising the air conditioning set temperature by 1°C can reduce electricity usage by about 10%. In winter, it prevents indoor heating radiation from escaping outside, allowing the heating set temperature to be lowered by 2-3°C, resulting in energy savings.
