“The development of ground-breaking, cost reducing, specialized chemical materials is emerging as an area that can change the future of the next generation display market.”

Etchant

Etchants are chemical substances used to dissolve the surface of metal or non-metal materials, chemically or electrochemically. 
In the production process of OLED, LCD, and touch panels, aluminum, copper, ITO, and silver are used for etching purposes. Particularly, in the OLED industry, fluorinated etchants are being used for the washing and etching of Si films.
Soulbrain is satisfying the needs of the display market through the supply of diverse series of hydrofluoric acid, peroxide, nitric acid, hydrochloric acid, and phosphoric acid based etchants developed with our proprietary technology.

Thin Glass (TFT-LCD / OLED)

The growing market of mobile devices such as smartphones and tablet PCs has stimulated an increasing demand for lighter and slimmer products. Following this trend, the need for glass slimming has also risen sharply. 
Through the introduction of a vertical spray process, Soulbrain has achieved improvement in areas such as product productivity and slimming uniformity, and we are always implementing our accumulated know-how to achieve superior product reliability. 
Soulbrain always strives for perfection through continuous research and development to improve productivity and develop processes for attaining higher quality products.

Optical Film

The growth of the mobile market has stimulated an increased demands to develop lighter and slimmer products. Accordingly, Soulbrain has been working on the development of products which stimulate improvements such as allowing the manufacture of lighter products through slimming, and reduction of the process steps through improved productivity. To this end, we have successfully developed and are producing products with the dual-composite prism, which combines two-prism sheets to one, while satisfying the overall quality requirements, such as high brightness, shortening of the assembly process, and improved wrinkle properties. Soulbrain’s optical films have continuously received a great market reaction and increased market demand.

Cerium Hydroxide

Cerium compounds are core raw materials for the production of etchant and ceria slurry used in the manufacturing processes of TFT-LCD and semiconductors. 
Recently, changes in technology in the manufacturing processes of TFT-LCD and semiconductors have stimulated an increasing demand for changes in material and higher quality standards. To meet such needs, the importance of the production and supply of raw materials has also been on the rise. Soulbrain is engaged in the production of diverse cerium compounds, such as cerium hydroxide and cerium ammonium nitrate.

  • Usage
    • TFT; Cerium Carbonate and Cerium Oxide CAN: main raw materials in CAN Ceria Slurry, which is a main material in etchant for LCD; Cerium hydroxide: the main raw material in cerium carbonate.
  • Major Products
    • Cerium Hydroxide
    • Cerium Ammonium nitrate
    • Cerium Carbonate
    • Cerium Oxide
