Product Description
DOWSIL™ CN-8880 Non-Curing Thermal Grease for Heat Sink Gap Filling
DOWSIL™ CN-8880 is a non-curing, thermally conductive silicone paste engineered for heat sink gap filling applications. This specialized material maintains stable performance at high temperatures while providing excellent thermal transfer and electrical insulation properties.
Product Overview
This grease-like silicone material is heavily filled with thermally conductive metal oxides and designed to maintain consistency and stable performance at temperatures up to 177°C (350°F). It effectively transfers heat from electronic components like transistors and diodes to heat sinks or chassis, enhancing heat dissipation and increasing overall device efficiency and reliability.

Performance Characteristics
CN-8880 exhibits high viscosity (836,000 cP) which contributes to minimal flow (slump of 0.4 cm) and excellent stability after application. It demonstrates low volatility (0.14%) and maintains its dielectric strength of 9 kV/mm even under demanding conditions. The combination of low oil bleed and high-temperature stability makes it suitable for applications requiring long-term reliability without drying out or migrating.
Application Areas
DOWSIL™ CN-8880 is specifically designed for gap-filling between heat sinks and various heat sources such as transistors, diodes, and rectifier bases. Information from Dow Corning indicates its suitability in power supplies, automotive electronics, and power conversion modules where stable thermal performance and electrical insulation are critical over a wide temperature range.
