Haydale signs agreement for screen printable graphene ink aimed at the sensor market

Haydale forms joint development and supply agreement with Dowton to create screen printable graphene inks and pastes that can be customised to meet customer needs

7 Apr 2016 | Editor

Haydale Graphene Industries has announced an agreement with Taiwan based Dowton Electronic Materials (Dowton) for the development, production, sales and marketing of a Haydale-branded graphene enhanced screen printable ink which will be aimed initially at the biomedical market (the Agreement).

The Agreement is for an initial term of 5 years with automatic renewal thereafter subject to a 6 months termination clause. Production quantities for commercial applications are anticipated in 2016 with leads already under evaluation.

In the Agreement, Haydale will retain the exclusive rights to sell the developed inks into Europe, the Americas, Korea and Southeast Asia, whilst Dowton will have exclusive rights to sell the developed inks in their home market of The Republic of China (Taiwan) and also market the ink to existing customers in Japan and other territories.

Haydale has worked with Dowton to create a range of graphene enhanced screen printable inks and pastes that can be rapidly altered to precisely suit customer needs.

Dowton has existing customer demand for conductive inks incorporating both carbon and metals (such as Palladium, Silver Copper, and Nickel), and will continue to sell existing products under its own Dowton brand.

Ray Gibbs Haydale CEO said, "Working with Dowton has been enlightening in that they get things completed quickly with minimum fuss. Their technical expertise is outstanding along with production facilities and equipment. They have helped us to, quickly, produce an excellent base conductive ink (or as they describe it a paste) that has been built on our existing product. The developed paste is specifically designed for the screen printing of bio medical sensors, which is a substantial market, especially in the Far East. Even after 15 years of industry experience Dowton has expressed to us how surprised they were with the superior performance of our graphene based paste and have stated they have customers ready to trial the product. We therefore anticipate revenues from this Agreement during 2016."
Mr Hsu Shen-An, the Dowton CEO said, "Working with Haydale has been surprisingly easy and the quality of the graphene pastes we have tested are simply some of the best performing we have seen, especially for conductivity and stability of performance, which is crucial for repeat sales. We are very excited by Haydale's graphene paste and have expectations of strong interest from our existing customer in the bio medical sensor market."


About Haydale

Haydale has developed a patented scalable plasma process to functionalise graphene and other nanomaterials. This enabling technology can provide Haydale with a rapid and highly cost-efficient method of supplying tailored solutions to enhance applications for both raw material suppliers and product manufacturers.

Functionalisation is carried out through a patented low-pressure plasma process that treats both mined, organic fine powder and other synthetically produced nanomaterial powders, producing high-quality few layered graphenes and graphene nanoplatelets. The process can functionalise with a range of chemical groups, with the level of functionalisation tailored to the customer’s needs. Good dispersion improves the properties and performance of the host material and ensures the final product performs as specified.

The Haydale plasma process does not use wet chemistry, nor does it damage the material being processed; rather, it can clean up any impurities inherent in the raw material. The technology is a low energy user and most importantly environmentally friendly. The Haydale process is a patented enabling technology, allowing the Group to work with a raw material producer who seeks to add value to the base product and tailor the outputs to meet the target applications of the end user.

Haydale, based in South Wales and housed in a purpose-built facility for processing and handling nanomaterials, is facilitating the application of graphenes and other nanomaterials in fields such as inks, sensors, energy storage, composites, paints and coatings.
