Product Description

The 846 Carbon Conductive Grease is an electrically conductive silicone grease for improving electrical connections between sliding surfaces and parts. The 846 grease is designed to lubricate while maintaining good grounding connection. It inhibits corrosion and repels humidity providing an economical way to protect switches or to bridge the gap between contacting surfaces for EMI shielding applications. It is also great for providing electrical continuity between irregular or pitted surfaces. 5 year shelf life. 40 to 104 degree F storage temperature limits. -40 to 248 degree F service temperature. Maximum coverage (for 25 micrometer thickness): less than 28,600 sq cm. Volume conductivity: 8.57 mS/cm.
