• Household appliances
many of the products we rely on every day. Henkel is a leader
in specialized and cross-functional ink formulations for printed
electronics and its line of LOCTITE brand electronic inks has
been enabling leading-edge printed electronics for well over
three decades.
With a broad portfolio of silver, carbon, dielectric and clear
conductive inks, Henkel is making today’s medical solutions,
in-home conveniences, handheld connectivity and automotive
advances reliable and effective. Our inks serve multiple
markets including consumer, displays, medical, automotive and
RFID. They are also used in the manufacture of:
• Flexible circuits for membrane touch switches
• Keyboards for desktop and notebook PCs
• Heating elements
• Automotive sensors
• Biosensors, EKG/ECG electrodes, TENS pads and
Iontophoresis pads
• Antennas for contactless smart cards and RFID labels
Like most things in electronics, the majority of applications
that incorporate printed electronics are getting finer in
dimension and more complex in functionality. Henkel’s
ability to formulate inks that address the demands of fineline printing, while maintaining robust conductive and other
functional properties, sets us apart from the competition, and
has led to technology leadership within our comprehensive
portfolio of inks for printed electronics.

AUTOMOTIVE
Today’s automotive devices – from sensors to heating elements – are subjected to harsher conditions than ever before. Smaller
form factors and rising temperatures mean automotive sensors that control air bags, braking systems, steering control and
wheel position, among others, must be able to withstand high temperatures, increased vibration and, in many cases, exposure
to automotive fluids. Henkel’s portfolio of silver-based, carbon-based and dielectric inks have been designed to perform
exceptionally well under extreme conditions and have been custom formulated for application-specific performance.

Many modern display technologies rely on indium tin oxide (ITO) transparent
conductors for touch screen control. While effective, the production of ITO is a
complex and costly process. To simplify manufacturing and lower overall cost,
Henkel has developed a new line of printable transparent conductive inks that
provide an additive, adaptable and cost-effective alternative to ITO for certain
display devices. These inks, in combination with a protective top layer ink, are
delivering outstanding results for industrial touch screens, but also for other
applications including membrane touch switches, automotive touch screens,
backlight switches, keyless entry devices, luminescent displays, printed LED
lighting, shielding, solar cells and high-amperage designs.

MEDICAL
For medical electronics products, reliability and dependability are critical. Patient comfort, less invasiveness, disposable
products and remote diagnostics are driving development in medical electronics. Biosensors such as glucose test strips,
EKG/ECG electrodes, TENS pads for muscle stimulation, iontophoresis pads for drug delivery and countless other medical
electronics applications depend on Henkel inks to provide accuracy, reliability and compatibility. Formulated to be
compatible with the human body and various interactive medical gels and chemicals, Henkel’s advanced inks are making
modern medical devices possible.

RFID
RFID technology is found in a variety of devices including smart cards, passports, credit cards, various transportation payment
systems and more. In addition to flexibility, adhesion and compatibility requirements, electronic inks used for RFID products
have to be capable of transmitting and receiving specific radio frequencies. All of the elements within the ink system have to be
formulated to interact effectively with RF fields and this requires materials that offer good permeability, surface roughness and
low impedance. Henkel has a long and successful history developing inks for RFID devices and this knowledge base is enabling
the next generation of these popular ID products.

INK CLASSIFICATIONS
Utilizing different ink pigments, such as silver and carbon, Henkel materials experts have formulated robust
carrier and resin systems to allow for outstanding ink performance within a variety of ink classifications.
Silver – Silver is the most electrically and thermally conductive of all metals and is used as the basis for many of Henkel’s conductive
ink products. When combined with specific resin systems, Henkel silver inks can deliver better flexibility, crease resistance and
longevity. These inks find uses in many different applications within numerous market sectors and are available in UV, solvent
and formulations.
