Carbon Conductive Assembly Paste 847 Technical Data Sheet 847 Description The 847 Carbon Conductive Assembly Paste is an electrically conductive, low-cost, non-silicone product for applications needing stability over wide thermal ranges. The synthetic oil that is used has a low evaporation rate that allows the paste withstand high temperatures without drying. Further, the paste resists separation and bleeding very well, so it is unlikely to contaminate onto nearby areas. Applications & Usages The 847 paste improves electrical conductivity between electrical contacts and inhibits corrosion. Features and Benefits * High conductivity of 0.04 S/cm and low volume resistivity of 23 *cm * Doesn't separate or bleed like silicone-based oil * Withstands high temperature without drying, bleeding, flowing, or chemical degradation * Lubricates even at low temperature * Non-Corrosive * Zero VOC Usage Parameters Properties Shelf Life a) Temperature Ranges Value 5y a) Reported shelf life assumes room temperature storage and unopened container. Properties Constant Service Temperature Maximum Intermittent Temperature Storage Temperature Limits b) Value -50 to 250 C [-58 to 482 F] 200 C [392 F] -40 to 40 C [-40 to 104 F] b) Room temperature is acceptable. Cold storage avoids material separation and settling. If storing at 25 C, mix thoroughly to disperse filler before use.

Environmental Impact: The VOC (Volatile Organic Compound) content is 0% by WHMIS and European standards. Health and Safety: Wear safety glasses and disposable gloves to avoid exposures. HMIS(R) RATING NFPA(R) 704 CODES HEALTH: 0 FLAMMABILITY: 1 PHYSICAL HAZARD: 0 1 0 0 PERSONAL PROTECTION: Approximate HMIS and NFPA Risk Ratings Legend: 0 (Low or none); 1 (Slight); 2 (Moderate); 3 (Serious); 4 (Severe) Application Instructions The conductive paste performance depends on mainly on surface preparation. Improperly prepared contact surfaces can degrade the pastes' stability, conductivity, and lubrication characteristics. While the thickness and coverage are also important, the application method itself can easily be adjusted according to performance and application needs. Prerequisites * * Wear gloves and protective clothing (see 847 SDS). This product is extremely messy. Clean and dry the surface of the substrate to remove other oils, greases, dust, water, solvents, or any other contaminants. Recommendation: Use MG 824 Isopropyl Alcohol Equipment * * * Lint free cloth (for cleaning contact and for wiping excess residue) Spatula or stick application tools (sized appropriately for your application) Isopropyl alcohol or other residue-free organic solvents NOTE: Avoid oil-based cleaners (like WD-40) that are designed to leave a film on the metal surface. Contaminant oil or grease films may act like barriers reducing the electrical contact between the conductive paste and the metallic substrate. To apply the paste 1. Wipe the contact with a lint-free cloth. 2. Clean the contacts with isopropyl alcohol or other non-oil based cleaner. 3. Once dry, apply the paste with the application tool to the contact, ensuring adequate coverage and desired thickness.

Carbon black is hard to clean and may transfer to other surfaces by touch. Further, you may introduce contaminants that degrade the overall performance of the grease.
