Product Description

The Carbon Conductive Paste is electrically conductive silicone grease for improving electrical connections between sliding surfaces and parts. The Carbon Conductive Paste 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.

Applications & Usages

The Carbon Conductive Paste improves electrical conductivity between electrical contacts and inhibits corrosion.

Benefits

·                 ·       Improves electrical connections between irregular surfaces

·       Extends the life of contacts

·       Safe on plastics

·       Ensures electrical contact between loose or vibrating parts and small gaps

•            Volume resistivity of 114 Ω·cm  

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 846 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 grease

·       Wipe the contact with a lint-free cloth.

·       Clean the contacts with isopropyl alcohol or other non-oil based cleaner.

•              Once dry, apply the paste with the application tool to the contact, ensuring adequate coverage and desired thickness

ATTENTION

DO NOT apply or smooth grease with bare finger. 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

Storage

Store between -40 and 40 °C [40 and 104 °F] in dry area.
