Material Solutions for Printed Electronics

2 ALTANA

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 out-

standing reputation amongst our customers as valuable partner.

The exchange of technology and know-how between the decen-

tralized 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 pro-

ducts 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

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.CNTAs partner of the innovation alliance Inno.CNT, BYK is systemati-

cally 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 2007-2010. The

ELANTAS Beck was partner in the development of printable dielec-

tric inks.

BatMatStarting 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)

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 manufac-

ture 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, consi-

stent product quality and flexible response to constantly changing

market needs.

BeCTroN® DP SeriesThe materials and printing inks of Bectron® DP are innovative pro-

duct developments made by ELANTAS Beck, especially for the new

Printed Electronics market. All suggested products are VOC free

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 manufactu-

ring 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 pro-

duction 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 InksCoatings, printing inks and overprint varnishes require good wet-

ting of various substrates, excellent surface protection and defoa-

ming, and good pigment stabilization. BYK has the right additives

for both conventional drying and radiation-curing systems, aque-

ous 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 auto-

motive 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 ApplicationsBYK 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.

InstrumentsAppearance – such as gloss, haze, transparency – Color and about

any other paint, coating, or plastic physical property can be

measured with BYK-Gardner instruments.

NanoparticlesAs 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 diffe-

rent media like solvents and water with up to 10 % MWCNT con-

tent. 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.

• low odor• good flow out and printability• some coatings suitable for stamping and gluing • some coatings suitable for low migration• some coatings approved for direct and indirect food contact

Waterbased coatings Waterbased coatings cure through hot air and IR-radiation. Many

of ACTEGA's waterbased ink and coating systems are based on

renewable ressources. The coatings are customized to the different

printing applications and techniques.

They also offer customized functionalities:• low migration coatings• anti-slip and haptic coatings• heat resistant coatings• chemical resistance• primer etc.

effect coatingsACTEGA offers a wide range of effect coatings. Besides conventi-

onal metallic inks, we also offer a wide range of thermochromic,

fluorescent, pearlescent, glitter and phosphorescent inks is. Also
