The 838 Total Ground Carbon Conductive Coating is an economical, acrylic paint that is used to create conductive, static free surfaces with excellent characteristics. Coated surfaces reduce electromagnetic or radio frequency interference (EMI/RFI). The carbon in the coat resists rubbing off to the touch. Further, the cured coat is designed to withstand large temperature changes without cracking. High Conductivity, Low Surface resistivity of 250 ohm per square for one coat (1 mil). 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. 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. Dry to Touch: 20 minutes. Recoat time: 5 minutes. Full Cure at room temperature: 24 hour. Full Cure at 30 degrees C: 30 minutes. 3 year shelf life. RoHS compliant.
