Fluorine & Chemistry Technologies

By utilizing various features of fluorine and adding AGC’s unique technologies, we continue to develop new materials and components with unprecedented functions.

AFP (Anti-Fingerprint) agent (Afluid S550)

AFP property and fingerprint removability of AFP coated glass

AFP agent applied on the surface of the touch panel device (e.g., smartphones, tablet PCs) resists smudging, and fingerprints on the surface can be easily wiped off. Based on our unique fluorine chemistry technologies and advanced molecular design technologies, we succeeded in developing a new AFP agent (Afluid S550) that exhibits excellent durability. Furthermore, we are working on the development of more appealing products through combining this new material with glass material technologies and coating technologies.

We provide customer specific CMP solution.

The trend in the semiconductor industry continues to be towards smaller and faster integrated circuits. Global planarization is necessary for high density multilevel devices. Copper (low-resistivity) and Low-k (low dielectric) interconnection is desirable to obtain high speed devices. Chemical Mechanical Polishing (CMP) is essential to achieve such advanced device structures. Asahi Glass has been developing CMP slurries by employing material design and polishing technologies.

CYTOP

CYTOP has achieved extremely high optical transparency, of which the visible light transmittance is 95% or more, with amorphous properties completely different from existing fluoropolymers. Since this product can be dissolved with a special fluorinated solvent, it can be used in thin film coatings to a thickness of a few sub-microns. In addition, this innovative material possesses the characteristics of conventional fluoropolymers (i.e. chemical-resistant, electrical properties, water and oil repellency). Using CYTOP, we are developing polymer optical waveguides that exhibit extremely low loss at 1260-1650 nanometers, electret generators that can harvest energy from low-frequency vibrations, and FONTEX, flexible optical fiber capable of propagating large volumes of data.

Power generation mechanism of the micro-vibration power generator

* Power is generated through side-to-side vibration of the counter electrode and the electret electrode.

Materials for Polymer Electrolyte Fuel Cell

Principle of PEFC

Catalyst coated ion exchange membrane

A fuel cell is a clean and efficient power generator, producing water as its only byproduct. Polymer electrolyte fuel cells have been put into practical use as household fuel cell cogeneration systems, backup power sources, etc. They are also expected to be used for automobiles in the near future. Based on our unique fluorine chemistry and advanced synthesis technologies, we are developing advanced materials for high-performance and high durability polymer electrolyte fuel cells. Using these materials, we successfully operated a polymer electrolyte fuel cell continuously for over 6,000 hours at 120℃ which was the first in the world.

Surface patterned glass

Environment adaptable glass

AGC has created light-control glass by using nano-imprint technology, which is a simple and low-cost method to fabricate fine patterns. We are exploring new applications for this glass in electronics and environment-related industries, such as anti-reflection "moth-eye" structure to improve display quality, and environment-adaptable glass which adjusts solar transmission to keep the room cool in summer and warm in winter.
