Total Ground Carbon Conductive Coating is an economical, acrylic paint that is used to create conductive, static free surfaces with excellent characteristics.

• Compatibility:
• Adhesion—The 838 coating adheres to most materials found on printed circuit assemblies; however, it is not compatible with contaminants like water, oil, and greasy flux residues that may affect adhesion. If contamination is present, clean the surface to be coated first. For a list see the 838 Adherence Compatibility chart.

  IMPORTANT USAGE INFO:

  Do not use on thin plastics or on plastics where you want to keep original surface intact. The 838 spray contains solvents is designed to chemically etch plastic surfaces to help adhesion by melding the acrylic coating into the plastic substrate. This prevents flaking or peeling.

Applications & Usages:

Its primary application is to ground working surfaces to avoid static, but it can also be used to provide low cost EMI/RFI shielding, as a conductive base for some electroplating process, or anywhere in a manufacturing process where it is necessary to impart conductivity to a surface. Please see the Aerosol Application Instructions for details.
