DENATRON SP-801 is a conductive coating material (ink-type coating agent) developed based on a polythiophene-based conductive polymer named PEDOT:PSS. As PEDOT:PSS has an extremely high conductivity and works in the form of a thin film, it is almost invisible when the film is formed. When the conductivity is adjusted, SP-801 can be used in a wide range of applications, including transparent electrodes, and biomedical electrodes. SP-801 can be applied as a coating in general wet processes and heat-treated at a relatively low temperature to form a coating film. SP-801 is a water, or water/alcohol-based, conductive coating that mitigates environmental burdens.
