Shin-Etsu G-776 Silicone Oil Compound

Shin-Etsu G-776 Silicone Oil Compound

1. Product Overview

Shin-Etsu G-776 is a silicone oil compound that combines high reliability with excellent thermal conductivity and electrical properties. It is specifically engineered as a thermal interface material for applications requiring long-lasting performance under demanding conditions.

Compared to general-purpose silicone oil compounds, G-776 offers superior resistance against pump-out, creep, and oil separation, making it ideal for applications where sustained reliability is critical.

2. Features & Advantages

High Thermal Conductivity

With a thermal conductivity of 2.9 W/m·K, G-776 efficiently transfers heat away from critical components, ensuring optimal operating temperatures and extended device lifespan.

Excellent Electrical Insulation

Dielectric breakdown strength of 3.10 kV (at 0.25mm thickness) provides reliable electrical insulation for sensitive electronic components.

Superior Resistance to Pump-Out, Creep & Oil Separation

G-776 outperforms general-purpose products in resistance against pump-out, creep, and oil separation, ensuring consistent performance over extended service life.

Optimized Viscosity for Easy Application

Diluted with isoparaffin solvent, G-776 achieves low viscosity (60 Pa·s) for easy application while maintaining low oil bleed characteristics.

Wide Operating Temperature Range

Rated for use from -40°C to +200°C, G-776 performs reliably across extreme temperature environments.

Low Volatile Content

Low molecular-weight siloxane content (ΣD3-D10 ≤ 100 ppm) ensures minimal outgassing and maintains thermal performance over time.
