Description
Molykote 4 Electrical Insulating Compound (formerly Dow Corning DC4) is a silicone-based compound paste (sae as8660) with semi-flowable consistency that exhibits excellent dielectric strength and electrical insulating properties.
Applications
- As a lubricant and seal for cable connectors, battery terminals, rubber seals, elastomer and polymer O-rings
- Assembly of various metal on polymer and metal on rubber combinations
- A Moisture proof seal for transportation and industrial applications including ignition systems, sealed electrical connectors, disconnect junctions, and terminals where a semiflowable consistency material is appropriate.
- Consider using MOLYKOTE® 111 Compound or MOLYKOTE® 5 Compound if higher consistency material is needed related to electrical based applications or MOLYKOTE® 112 High-Performance Lube/Sealant for critical mechanical based applications.
Features
- High dielectric strength and excellent electrical insulating properties
- Good adhesion to most dry materials, including metals, elastomers, polymers and ceramics
- Semi-flowable rheology may allow compound to enter complex geometries
- Low volatility and evaporation
- Good moisture resistance and water repellency
- Good thermal oxidation stability
- Material tested to AMS8660 Tables 1-4 (see Typical Properties on tech data sheet)
- Certification to NSF 51 and 61, meets 21 CFR 175.30, Kosher Pareve, Halal

How to use
MOLYKOTE® 4 Electrical Compound can be applied by hand, brushing or wiping into the application.
Shear can impact the product rheology and cause increase in flow characteristics which can be a benefit
in some applications where material needs to flow into complex geometries. If the application is not tolerant
to variation in rheology characteristics, mechanical means of sealing or isolating the material is recommended.
Designed automation dispensing is possible but should be validated at customer prior to use due to high
shear from pumps. Silicone compounds should not be applied to surfaces that require painting or coating.
