SunChemical Gwent C2040706D7 Carbon/Graphite Ink (discontinued **)
Categories:	Fluid; Other Engineering Material; Ceramic/Metallic Coating
Material Notes:	Carbon Graphite Ink is designed for screen printing working electrodes. This product has a much higher resistance then other carbon products. The electrochemical performance of this paste is not very reversible on Cyclic Voltammetry. This product should be used in applications where Chrono amp is to be employed. This product has no significant hazardous materials. The ink is in a ready to use form at a viscosity suitable for automatic or semiautomatic screen printing. The ink should be gently stirred before use avoiding introduction of air bubbles. It is a Polymer System for printing on polyester, PVC, Polycarbonate etc and on alumina.
