Shin-Etsu HIVAC F-4 Diffusion Pump Oil 1000 mL Silicone Fluid

About Shin-Etsu HIVAC™ F-4 Vacuum Grease

OVERVIEW:

Shin-Etsu HIVAC™ F-4 is a high-purity silicone-based vacuum grease designed for sealing and lubricating components in high-vacuum systems and clean environments. It is engineered to exhibit low vapor pressure, excellent chemical stability, and minimal outgassing, making it suitable for critical applications in scientific, semiconductor, and industrial vacuum equipment. HIVAC F-4 helps maintain vacuum integrity while providing long-lasting lubrication and sealing performance.

KEY FEATURES:

Low Vapor Pressure
Formulated to perform effectively under high-vacuum conditions, helping to reduce gas release and maintain system vacuum stability.

Wide Temperature Range
Provides reliable lubrication and sealing over a typical service temperature range of -40°C to +200°C, depending on system design and requirements.

Chemical Inertness
Compatible with metals, glass, ceramics, and many elastomers. Its inert silicone base minimizes the risk of chemical interactions with system components.

Good Sealing Performance
Offers effective sealing of static joints such as ground glass, vacuum flanges, and O-rings, helping to prevent gas or moisture ingress.

Low Outgassing Characteristics
Designed to minimize contamination and migration, making it suitable for use in cleanroom and semiconductor manufacturing environments.

APPLICATIONS:

• Vacuum Laboratory Equipment – Used for sealing and lubricating ground glass joints, stopcocks, and vacuum connections.

• High-Vacuum Systems – Helps maintain vacuum integrity in scientific and industrial equipment operating at high or ultra-high vacuum levels.

• Semiconductor Process Equipment – Applied in components where low outgassing and chemical stability are essential for product quality and process consistency.

• General Industrial Use – Suitable for sealing static joints in assemblies requiring vacuum-tight performance.

PACKAGING:

Shin-Etsu HIVAC™ F-4 is typically available in 100g or 1kg containers. Packaging sizes may vary based on regional distribution.

INSTRUCTIONS FOR USE:

• Surface Preparation: Clean application surfaces to remove dirt, moisture, and previous lubricants. Ensure material compatibility with silicone-based grease.

• Application: Apply a thin, even layer to the sealing surface or contact area. Avoid over-application to minimize risk of migration under vacuum.

• Maintenance: Periodically inspect and reapply as needed to maintain optimal sealing and lubrication performance.

SAFETY AND HANDLING:

HIVAC™ F-4 is generally safe when used as intended. Avoid eye contact and ingestion. Use appropriate personal protective equipment (such as gloves) during handling, especially in cleanroom environments. Refer to the product’s Safety Data Sheet (SDS) for complete safety information and handling recommendations.
