Henkel PTC Inks Lend New Efficiency, Functionality to Heating Applications

The Electronics Group of Henkel today announced the development and commercial availability of LOCTITE ECI 8000 series printable inks, a line of positive temperature coefficient (PTC) materials ideal for heating applications.

A streamlined replacement to traditional copper wire and printed carbon, Henkel’s PTC materials are enabling new designs for a variety of products that require efficient and adaptable heating functionality.

“Conventional flexible heating has been achieved through the use of wires and carbon inks, which can be cumbersome and challenging,” explains Todd Williams, Henkel Global Product Manager for Inks and Coatings. “The LOCTITE ECI 8000 materials have exceptionally thin form factors, so can be printed for use within very tight spaces and in infinite patterns to accommodate various architectures.  And, the performance is as impressive as the materials’ design adaptability. They offer the best of both worlds.”

LOCTITE ECI 8000 PTC inks are self-regulating so that the temperature does not rise above its set point. With traditional flexible heating technologies, there is a linear relationship between voltage and temperature, which usually requires a control unit to regulate temperature and a fuse to prevent overheating. LOCTITE ECI 8000 PTC inks, however, have a non-linear relationship between voltage and temperature, ensuring no
overheating and eliminating the need for a fuse and, in some applications, a control unit as well.

Henkel’s unique PTC inks offer numerous benefits including rapid and uniform heating, self-regulation, reduced weight as compared to traditional flexible heating options, and sustainability through environmental stability, long life, lower power consumption and reduced waste. Though application possibilities are endless for Henkel’s PTC ink technology, early success has already been achieved for automotive products such as mirrors and windshields, consumer goods that require condensation control, floor and wall heating and seat heaters, among others.

“Previous flexible heating solutions, while effective to a point, had limitations in terms of space adaptability and consistent heat regulation,” concludes Williams. “Henkel’s PTC inks open up new possibilities for all types of products in terms of design, consumer safety, product longevity and lower costs.”
