Properties
DOTITE materials have good adhesion to a variety of substrates – including PET film, polyimide (PI) film, polycarbonate (PC), and other plastic substrates. DOTITE materials offer conformability to flexible substrates, bending resistance, high conductivity, and fine line printing – and they can be used with a variety of printing techniques. Additionally, DOTITE materials for electrical insulation for circuit protection, or adhesives for bonding film layers and mounting electrical components are available.
Applications
DOTITE materials are used for a wide variety of applications in multiple fields, including:
- Replacing FPC with a combination of FPC jumper circuitry and PET film membrane switches.
- Forming circuitry and electrodes for medical biosensors, wearable devices, and automotive sensors.
- Forming antennas for RFID (electronic tags), automotive transmitters, smart phones, and other mobile devices.
- Heating lines for defrosters, defoggers, and heaters.
- Replacement for resistive layers for circuitry.
