Material Solutions for Printed Electronics
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.
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.

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.

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 2007-2010. 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)

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:

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.
