  ThermoPrint™ Conductive Carbon Paste is a thermoplastic, screen-printable conductive material engineered for applications requiring low-temperature processing, reliable electrical performance, and strong substrate adhesion. The paste can be deposited as a single, continuous layer using standard screen-printing techniques, enabling efficient and repeatable pattern formation.

  After curing at a relatively low temperature of 140 °C, the material develops a stable conductive network with consistent sheet resistance. Its thermoplastic nature provides mechanical robustness while maintaining flexibility, making it suitable for both rigid and polymer-based substrates. Optimized rheology ensures smooth printing behavior, dimensional accuracy, and uniform film thickness across printed features.
