Loctite® ECI 8000 E&C series is an innovative line of Positive Temperature Coefficient (PTC) functional inks for heating elements manufactured by Henkel Electronic Materials, and now available from Tekra. These carbon inks are formulated to increase their electrical resistance exponentially with rising temperature, cutting off the flow of current powering the heater once the desired temperature range is reached. This greatly reduces the safety risk associated with overheating since the inks themselves are self-regulating. Temperature resistance values range from high to low power (105°C to 55°C).

PTC resistor inks are engineered to maintain stable properties that excel in multiple self-regulating heating environments. This self-regulating "tuned" action makes PTC carbon resistor inks ideal for heating elements used in various applications, including commercial and residential floors & walls and exterior auto lights, back-up cameras, side mirrors, and defoggers.
PTC Carbon Resistor ink compositions can be printed via screen or rotary processes. These inks are compatible with silver and dielectric inks printed on base PET, PEN, and PI film substrates. For additional information, please click here.
