Technical Product Information |  |
| DOWSIL™ TC-4525 CV Gap Filler Kit Blue 142 G |
| Product Overview |
| DOWSIL™ TC-4525 CV Gap Filler Blue is a 2-part (1:1 mix ratio), 2.6 W/m.K thermally conductive silicone gap filler formulated for heat dissipation in automotive electronics, sensitive optical modules, and power assemblies. Featuring Controlled Volatility (CV) technology, it minimizes low-molecular-weight siloxane volatile species to prevent condensation and fogging on delicate optical lenses and sensitive electrical contacts. Upon dispensing and cure at room or elevated temperature, it forms a soft, low-stress silicone elastomer that absorbs mechanical shock and thermal expansion. The 142 gram dual cartridge package provides an ideal size for manual dispensing, prototype development, and precision small-batch assembly. |
| Key Features and Benefits |
| • High Thermal Conductivity (2.6 W/m.K): Ensures efficient heat transfer from heat-generating components to heat sinks or housings. • Controlled Volatility (CV): Formulated with low volatile siloxane content to protect sensitive optics and electrical contacts against fogging. • Soft, Low-Stress Elastomer: Cures into a soft, flexible matrix that cushions fragile components against thermal cycling and vibration. • 1:1 Mix Ratio Dual Cartridge: Convenient dual cartridge packaging enables precise, void-free mixing through a static mixing nozzle. • Slump-Resistant Dispensing: Holds its shape upon dispensing, preventing sag or migration on vertical surfaces prior to cure. • Wide Thermal Stability: Maintains physical and thermal integrity across operating temperatures from -45°C to +150°C (-49°F to +302°F). |
| Technical Specifications |
| • Appearance / Color: Blue • Packaging / Net Weight: Dual Cartridge Kit / 142 G • Chemical Base: 2-Part Thermally Conductive Silicone (Addition-cure / Platinum catalyst) • Mix Ratio (by weight / volume): 1:1 • Thermal Conductivity: ~2.6 W/m.K • Density (Cured): ~2.9 g/cm³ • Service Temperature Range: -45°C to +150°C (-49°F to +302°F) |
| Applications |
| • Automotive electronics, ADAS camera/sensor modules, electronic control units (ECUs), and battery management systems (BMS). • Thermal interface material for sensitive optics, LiDAR, and radar assemblies sensitive to siloxane outgassing. • Power electronics, inverters, LED lighting drivers, and telecommunication circuit boards. • Filling variable thermal gaps between complex electronic components and heat dissipating housings. |
Usage Note: The 142 gram dual cartridge requires a compatible manual or pneumatic dispensing gun fitted with a static mixer nozzle. Discard a small initial bead to ensure complete 1:1 mixing. Avoid contact with sulfur, amines, or organometallic compounds to prevent platinum catalyst cure inhibition.
