1 Material Solutions for Printed Electronics

2 The brand ALTANA represents a global specialty chemical group. It comprises the holding company ALTANA AG and four operating divisions: ELANTAS Electrical Insulation, ECKART Effect Pigments, BYK Additives & Instruments and ACTEGA Coatings & Sealants. The four divisions occupy a leading position in their target markets with respect to quality, product solution expertise, innovation and service. Products made by companies in the ALTANA Group are sold in over 100 countries and their quality has earned us an outstanding reputation amongst our customers as valuable partner. The exchange of technology and know-how between the decentralized companies of the division as well as the corporate culture of ALTANA focused on markets, service and innovations makes us a preferred supplier for very different industries worldwide. Our strength lies in offering customized solutions and specialty products that create added value for our customers. In order to strengthen R&D efforts of its subsidiaries in the areas of future technologies the idea of ALTANA Technology Platforms was born. The ALTANA technology Platform Printed Electronics was established in 2011 in order to combine the R&D efforts of the single divisions in this field, to facilitate the information exchange and to use synergies. Innovative product development is supported by high technical standards in the application laboratories. Therefore the following measurment equipment and facilities are provided within the ALTANA Technology Platform Printed Electronics. Complete Electrical Characterization Surface Analysis Screen-, Flexo- and Gravure Printing Standard ink tests UV inline curing, IR curing Clean room facilities Full assembly of OFETs and Capacitors Metallization, Spin Coating Water Permeability Determination Climate Stressing Temperature Cycling Microscopy, SEM Particle Size Analysis Adhesion Measurement Equipment 2 ALTANA

3 Our ALTANA Technology Platform Printed Electronics, as well as our subsidiaries are always open for cooperation. Besides our collaborations with well-known universities, we took and take integral part in the following founded projects: Inno.CNT As partner of the innovation alliance Inno.CNT, BYK is systematically pursuing basic research in the field of CNTs. The initiative is sponsored by the German Federal Ministry of Education and Research. Its aim is to establish a global lead market for CNTs in Germany. MaDriX The German Federal Ministry of Education and Research funded project MaDriX aimed for the Standardization and Synthesis of new materials for printed RFID-labels from The ELANTAS Beck was partner in the development of printable dielectric inks. BatMat Starting in spring 2011, the BatMat project is the freshest public financed project the ECKART GmbH joined. Again it is financed by the German Federal Ministry of Education and Research and aims for the development of new types of printed batteries. We are part of the following organizations and networks: organic and printed electronics network of northern Germany organic electronic association (oe-a) ALTANA 3

4 ELANTAS Beck is a subsidiary of ELANTAS Electrical Insulation. ELANTAS develops and produces wire enamels, impregnating resins, sealing compounds, conformal coatings and casting resins, which are used for the isolation of electric motors, generators, printed circuit boards, sensors and electronic modules. For the printed and organic electronics industry ELANTAS Beck develops and produces insulating polymers, encapsulations materials and glues based on alkyd, epoxy, melamine, polyimide, polyurethane, unsaturated polyester and other resins chemistry. Our experience covers not only resin production and basic research of our own R&D department, but also our extensive application support and technical service. In our application department we offer clean-room conditions, a flexo- and gravure printer for printing tests of the insulators and encapsulation materials. We also have the possibility to manufacture and measure organic field effect transistors (OFET) and make stability tests of our materials in climatic test cabinets. This allows the control of products' properties right from the very start, consistent product quality and flexible response to constantly changing market needs. Bectron DP Series The materials and printing inks of Bectron DP are innovative product developments made by ELANTAS Beck, especially for the new Printed Electronics market. All suggested products are VOC free and fast processible: Insulators / Dielectrics for Capacitors, Organic-Field-Effect-Transistors (OFETs), RFID-Tags, Sensors or Solar cells high dielectric strength low leakage current high K or low K gravure, flexo or screen printable Glues for OLED-Displays and OLED Lights low permeation rates The chemistry of Bectron DP series is widely spread from alkyd, epoxy, melamine, polyimide, polyurethane to unsaturated polyester. Encapsulation / Barrier Layers for OFETs, Printed Antennas, Printed Batteries, etc. good barrier against environmental influences mechanical protection climate and UV stable gravure, flexo or screen printable 4 ALTANA

5 BYK is one of the world s leading suppliers in the additives and instruments sector. Additives are chemical substances that even when added in small quantities enhance product properties such as scratch-resistance or surface gloss. Moreover, entire manufacturing processes can also be optimized by means of additives. The main uses for BYK additives include application areas in the coatings, printing ink and plastics industries. But the demand for BYK additives is also growing rapidly in paper coatings, in the production of adhesives and sealants and in construction chemistry because they are also being used to continuously optimize product properties and manufacturing processes in these sectors as well. In 2009, BYK expanded its product portfolio with the addition of raw materials used in the manufacture of release agents for aluminum die-casting. Additive for Coatings and Printing Inks Coatings, printing inks and overprint varnishes require good wetting of various substrates, excellent surface protection and defoaming, and good pigment stabilization. BYK has the right additives for both conventional drying and radiation-curing systems, aqueous or solvent-borne. Additives for Adhesives & Sealants Gluing as a means of joining different components has become an integral part of today s modern industry sectors such as the automotive industry or the electrical industry. BYK is your competent technology partner when it comes to improving the properties of adhesives and sealants systematically. Additives for Plastics Applications BYK plastics additives are used to optimize nearly all aspects of your system. With BYK plastics additives you are able to positively influence the processing properties of your system as well as its mechanical and aesthetical properties and, ultimately, the quality of your final product. Instruments Appearance such as gloss, haze, transparency Color and about any other paint, coating, or plastic physical property can be measured with BYK-Gardner instruments. Nanoparticles As a key technology of the 21st century, nanotechnology offers great potential for developing new additive solutions. NANOBYK additives, supplied as ready-to-use dispersions, improve UV or scratch resistance using cerium oxide or zinc oxide and alumina or silica nano particles. Electrical conductivity is achieved using BYK additives based on CNT. BYK has developed dispersions in different media like solvents and water with up to 10 % MWCNT content. Such dispersions exhibit a high degree of dispersion state of MWCNT and are compatible to a large variety of coating systems and plastics. All Nanodispersions are offered for UV-, water- and solvent based ink & coating formulations. ALTANA 5
