(11th March 2015)

Nitride Solutions, a US developer and manufacturer of advanced nitride substrates for LEDs, lasers, and power electronics, announced today that it has successfully closed $3M in new funding as Hansol Chemical, Greenpoint Global Mittelstand Fund, and Silicon Pastures Angel Investment Network joined the company's investor group.

Funds will be used to expand production of the company's AlN substrate offerings, as well as to accelerate market introduction of its high-performance thermal management coatings.
Nitride Solutions CEO Jeremy Jones said he is extremely pleased to have Hansol and Greenpoint as investors. "With Hansol we are gaining an important partner in Korea and Japan to exclusively represent our products and share critical customer feedback," Jones said. "Greenpoint brings deep knowledge of companies in Asia that are seeking US manufacturing capability."
Yeunjoo Cho is the vice president of strategic planning for Hansol Chemical. Hansol Chemical is part of Hansol Group and is a leading manufacturer of specialty chemicals in Korea. "We believe that Nitride Solutions' technologies for UV LEDs is truly next-generation and are very excited about this investment and partnership," Cho said. "A partnership of this nature will help us accelerate toward technical leadership in electronic chemicals. In return, Nitride Solutions will gain partnership in the high-demand markets of Asia and will be able to maximize the growth of the company."
Teresa Esser is the managing director of the Greenpoint Global Mittelstand Fund and Silicon Pastures Angel Investment Network. The Greenpoint Global Mittelstand Fund is a private equity fund addressing the significant challenge of exits. The fund's dominant investment strategy is investment in American companies geared for Asian exits, and it maintains considerable relationships with firms in Asia that specifically seek American manufacturing and technology companies.
"We are very pleased with our investment in Nitride Solutions' unique technologies and solutions for advanced electronics," Esser said. "I believe that they bring solutions to some of the most difficult global issues and I look forward to working with their team to bring this to success."
Hansol Chemical, Greenpoint Global Mittelstand Fund, and Silicon Pastures Angel Investment Network join Nitride Solutions' existing national investment group including angel investors from Kansas, Nebraska, Oklahoma, Washington (DC), California and Alaska.
Founded in Kansas in 2009, Nitride Solutions' focus is developing volume production processes that will bring new AlN products to advanced electronics markets and enable goods that address global needs for safe water and air, more reliable power generation and transmission, and higher-speed communications.
AlN has a unique combination of properties including wide bandgap, high thermal conductivity, and high voltage resistance. The wide bandgap makes it suitable for deep UV and very high-power devices. Its high thermal conductivity and high voltage resistance enable thinner structures and faster heat reduction, which allow for higher power operation without premature failure.

Introducing Hydrogen Peroxide

Introducing Hydrogen Peroxide (H₂O₂)

Hansol Chemical’s H₂O₂ is a transparent chemical compound with strong oxidizing properties. It is used in bleaching pulp for paper, dying textiles, treating waste water, and even has uses in pharmaceuticals.

In the high tech field H₂O₂ is used as an etchant for LCD/PCB panels and circuit boards and as a ultra nano cleaning agent for semiconductor wafers.

Hydrogen Peroxide is recognized worldwide as an Eco-friendly product and is continually developing new uses in many environmental fields.

As Korea’s No.1 Hydrogen Peroxide manufacturer, Hansol Chemical is the national standard for excellence in service, technical ability and customer satisfaction.

The Science of Hydrogen Peroxide

Hydrogen Peroxide is a odorless, colorless, transparent and acidic liquid compound. Alone it is chemically stable, but when mixed with metal or other organic materials a chemical reaction occurs leaving behind decomposed residue of water and oxygen.

Depending on the environment and force of the reaction, unintended mixtures can be explosive but since water and oxygen are the results of any reaction there is no concern for secondary pollution or hazard.

Manufacturing

Hydrogen Peroxide is made from a reaction between Hydrogen and Oxygen.

Sounds simple enough?

Here is an example of the process chain that results in our final product.

(Hydrogenation→Oxidation→Extraction→Concentration)

>>Hydrogenation

Hydrogen is collected in a chamber and mixed with a solution called Anthraquinone (AQ) which acts as a catalyst to create Hydroquinone (HQ).

>>Oxidation

The newly made hydroquinone is mixed with oxygen and the chemical reaction creates two bi-products. Hydrogen Peroxide and Anthraquinone. H₂O₂ is pumped into the extraction chamber and the AQ is collected and recycled back for reuse in the hydrogenation process.

>>Extraction

Water is injected into the fresh Hydrogen Peroxide and the raw batch is produced.

>>Concentration

Here the final touches are made to create the specific concentration and grade of H₂O₂ tailored to fit each customers’ needs.

The combined process, called auto-oxidation, is just one part of Hansol’s technical expertise that has enabled it to be the nation’s #1 manufacturer of hydrogen peroxide.

Hydrogen Peroxide Product Category and Applications

Hydrogen peroxide is applied to various fields depending on the level of concentration. Hansol Chemical is continuously developing new formulas that can be applied to new markets that have never been applied using H₂O₂.

1) Product category

Concentration       Packing unit

2) Applications

- Oxidation bleacher for paper and pulp industry, bleacher for textile industry

- Cleaning agent for semiconductor field, etchant for LCD/PCB industry

- Bleacher/germicide for food industry, germicide/disinfectant for fish farming fields

- Fenton Oxidant for waste water treatment plant

- Eco-friendly material synthesis/reaction application to new markets
