Conductive Carbon Inks and Pastes

Our conductive carbon pastes can be used for a wide range of applications including; biomedical sensors, automotive, electrodes, aerospace, printed heaters, printed resistors, membrane touch switches, keyboards and thin-film photovoltaic including perovskite solar cells.

Long-life, high reliability thermoset carbon pastes (410XS series) are capable of withstanding extreme mechanical abrasion tests. These pastes are typically used for printed resistor and potentiometer applications and are MEK resistant. Our low temperature cured carbon pastes (4300S series) are ideal where printed resistors are required on flexible substrates, spanning a broad resistivity range and are compatible with substrates such as paper and PET. The 4311S product offers excellent electrical conductivity (<20 Ω/□/25µm) and is ideal for thin-film PV applications.

The 4511S (15 Ω/□/25µm) is a thermoplastic carbon paste system, that offers fast drying and is designed for coating on flexible plastic substrates.   Thermoplastic pastes with increased sheet resistance are also available, please contact us for further details.

DM-CAP-4701S is a high electrically conductive paste for perovskite solar cell use.  This material provides excellent power conversion efficiency whilst providing excellent long term durability performance.  This material is typically screen printed or blade coated although syringe based systems are also available.  DM-CAP-4703S incorporates additives to allow improved charge transfer by modifying the electrode work function and higher efficiency solar cell devices.

We provide our materials to a global customer base, offering a flexible delivery service from low volume samples to high volume to meet our customer’s production needs.

We can rapidly tailor formulations for specific customer requirements.
