Sun Chemical and the DIC Corporation Acquire Gwent Electronic Materials Ltd.

The shareholdings of Gwent Electronic Materials Ltd, Applied Enzyme Technology Ltd, Gwent Sensors, Gwent Biotechnology Systems Ltd, and LRH Ltd. have been acquired by Sun Chemical and its parent company, the DIC Corporation.

Our group considers this an exciting opportunity to expand and offer our range of products globally. The synergistic effect of working with a company which is already heavily involved in the electronic materials market will be mutually beneficial as access to Sun Chemical and DIC's range of basic raw materials, dedicated facilities, and larger scale manufacturing plants, will enable Gwent to expand rapidly. Additionally, development of new products will be much faster than is currently possible while utilising only our own resources.

The current directors will continue to work for the companies so that all advantages of being part of a larger group can be realised. The facility in South Wales will continue to operate as it currently does. To this effect, we have a long-term lease upon the development and manufacturing site that we currently operate from.

We emphasise there will be no change in the points of contact for any of our customers and distributors; all will continue as at present. Product will continue to be supplied from our Pontypool factory under our quality systems for medical products of ISO 13485 and for automotive products of ISO 16949.

September 2013

Gwent Electronic Materials (“GEM”), it has developed a new Carbon/Graphite Ink for heavy metals detection.

June 2013

“GEM” has developed graphene based inks with properties that now quickly enable its customers to use graphene in a wide range of applications.These new graphene inks enable the commercialisation in the near future of smart packaging, printed batteries, electrochemical sensors, flexible displays and potentially touch screens.

November 2012

The launch of our new UV curable systems

UV curable Silver based ink for flexographic printing

A UV green translucent dielectric material designed for screen printing.

This is compatible with most substrates and other printing pastes.

Rotary Screen printing

Our group is in the late development stages and pilot scale runs with a number of inks suitable for the continuous printing of electoluminecent lamps, biosensors circuits...etc.
