"Looking AR" is the ultimate new glass that is not corroded by alkali. When comparing alkali corrosion resistance, it shows results of approximately 800 times against aluminosilicate glass and 1750 times against borosilicate glass, demonstrating its superior alkali resistance. Its bending strength is 270 N/mm² (27 kgf/mm²), which is excellent mechanical strength compared to existing glasses. Additionally, it has an excellent heat resistance with a maximum operating temperature of 500°C, surpassing that of existing glasses. 【Features】 ■ Excellent alkali corrosion resistance ■ Excellent mechanical strength ■ Excellent heat resistance *For more details, please refer to the catalog or feel free to contact us.

"Clear Coat Glass" is a type of glass that has been firmly bonded to a Teflon PFA resin on its surface using our advanced technology. This product exhibits excellent chemical resistance, showing no effect from chemicals used in the chemical industry, such as acids, bases, halogens, alcohols, and ketones, even at their boiling points. Furthermore, it has a unique property that makes it difficult for substances to adhere; the surface coated with Teflon PFA repels water and is not stained by oil. It also possesses heat resistance, showing no abnormalities such as peeling when subjected to repeated thermal shock, being heated to 170°C and then immersed in water at 10°C. Additionally, in the event that the glass is damaged by impact, it prevents the scattering of shards and reduces the ejection of fluids. 【Features】 ■ Chemical resistance ■ Non-stick property ■ Heat resistance ■ Transparency ■ Safety *For more details, please refer to the catalog or feel free to contact us.

Looking AR(R) contains various oxides that improve alkali resistance. These include zirconia (ZrO2), rare earth oxides, and alumina (Al2O3), which themselves have low solubility against alkalis (maintaining low solubility even in glass compositions), and it has been confirmed through experiments that alkali resistance is dramatically improved. Additionally, due to the requirements of industrial glass applications, we not only aim to enhance alkali resistance but also consider the thermal stability, mechanical strength, and meltability during glass melting in the manufacturing process. For more details, please contact us or refer to the catalog.

The metal-fused sight glass, Clinport(R), is a product born from a revolutionary technology that powerfully and hermetically fuses special glass directly to the inner wall of a metal ring, while utilizing the difference in thermal expansion coefficients between the metal ring and the glass to enhance the glass. It has obtained patents in Japan and the United States, proving the uniqueness and excellence of its technology. Since the glass and metal are integrated, it possesses an astonishing strength for a glass product. Therefore, there is almost no concern about glass breakage. If the glass does break, the damage remains confined to the surface layer, appearing in thin, flake-like pieces, and the destruction progresses gradually, which prevents the contents from spilling out in the event of a breakage, thus earning high safety ratings. For more details, please contact us or refer to the catalog.

Clear Coat Glass® is a coating that has been firmly bonded to the surface of glass using advanced technology from Nihon Clingage Co., Ltd., with a fluororesin (PFA). Since it is coated with fluororesin (PFA), it possesses the chemical resistance of fluororesin (PFA). The PFA film has slight permeability, so if chemical resistance is the goal, it is necessary to coat it with a thicker film. Additionally, the surface coated with fluororesin (PFA) repels water and is not stained by oil. It has properties that prevent most substances from adhering, so the surface remains mostly clean. Even if it does get dirty, it can be easily cleaned. For more details, please contact us or refer to the catalog.

The MS type reed switch incorporates a latching reed switch. In the OFF state, it activates and turns ON when the N pole of the magnet approaches the reed switch. It maintains the ON state even after the N pole passes by and the magnetic field disappears, and when the N pole returns to the switch, the latching is released and it turns OFF. The switch operation varies according to the requirements of the process. The MS type reed switch for MG (magnet float) level gauges is designed to allow for very easy implementation of switch operation changes on-site.
