ShinEtsu G-331 is a high shear silicone damping grease designed to provide controlled resistance and stable motion in mechanical systems subjected to high loads and torque. It delivers a dense, consistent tactile feel during operation, allowing components to move smoothly while maintaining strong resistance against sudden acceleration or vibration. In practical use, it supports predictable damping behavior over long service periods, helping users achieve precise motion control and long-term operational stability without frequent reapplication.

• High Shear Strength - ShinEtsu G-331 High Shear Silicone Grease is formulated as a high shear silicone damping grease with a kinematic viscosity of approximately 5,000 mm²/s at 25 ℃, providing strong resistance to motion under load. This viscosity level supports controlled deceleration and stable damping performance in systems exposed to continuous mechanical stress. The grease maintains consistent shear behavior across repeated motion cycles, supporting reliable resistance characteristics.

  
  

• Load Bearing - With a specific gravity of approximately 1.02 at 25 ℃, ShinEtsu G-331 delivers a balanced density that supports stable load distribution on contact surfaces. This density profile allows the grease to remain in place under pressure without excessive migration. It supports sustained load-bearing performance in assemblies where component weight and torque are critical factors.

  
  

• Adhesion Stability - ShinEtsu G-331 exhibits strong adhesion to metal surfaces, supported by its grease structure and refractive index of approximately 1.405 at 25 ℃. This adhesion helps maintain a continuous lubricating and damping film under dynamic conditions. The stable film reduces the risk of dry contact during long-term mechanical operation.

  
  

• Mechanical Durability - The silicone base structure of ShinEtsu G-331 supports durability under repeated mechanical stress and vibration. The grease resists breakdown during extended shear exposure, maintaining damping consistency over time. This durability contributes to reduced maintenance frequency in high-duty mechanical systems.

  
  

• Thermal Consistency - ShinEtsu G-331 High Shear Silicone Grease maintains stable rheological behavior across a wide operating temperature range typical for industrial and automotive mechanisms. Its viscosity profile remains controlled during temperature fluctuations encountered in service environments. This consistency supports predictable damping performance under varying thermal conditions.

• Heavy Mechanisms - ShinEtsu G-331 is applied in heavy-duty mechanical assemblies where controlled motion and resistance are required. Its high viscosity supports stable damping in components exposed to high torque and continuous load. This helps maintain precise mechanical response in demanding operational settings.

  
  

• Industrial Joints - In industrial equipment joints, ShinEtsu G-331 provides controlled resistance that supports smooth articulation under repeated motion. The grease helps manage vibration and sudden movement changes. This contributes to longer joint service life and stable equipment operation.

  
  

• Automotive Gears - ShinEtsu G-331 is used in automotive gear and actuator systems requiring resistance to rapid motion. Its shear-resistant properties support consistent damping during gear engagement and disengagement. This improves motion control reliability under variable driving conditions.

  
  

• Appliance Controls - In large appliance control mechanisms, ShinEtsu G-331 supports smooth yet resistant movement of knobs and sliding components. Its stable adhesion helps maintain consistent feel over extended usage cycles. This supports reliable user interaction and long-term performance.

  
  

• Aerospace Assemblies - ShinEtsu G-331 is suitable for aerospace mechanical assemblies where controlled damping and durability are required. Its stable physical properties support predictable performance under mechanical stress. This contributes to controlled motion behavior in precision aerospace components.
