9661E TDS-EN-R.pdf
9661E is a one-component room temperature vulcanising (RTV) silicone rubber designed for critical bonding and sealing applications in electronics and mechanical systems.
Its dealcoholized curing mechanism ensures no corrosion to metal substrates, making it ideal for sensitive electronic components. Compliant with RoHS standards, 9661E balances reliability with environmental safety, delivering consistent performance from -40°C to 150°C.
Applications
- Electronic Component Bonding & Fixing: Secures ICs, capacitors, and sensors to PCBs or casings, resisting thermal cycling and mechanical vibration.
- Electrical Equipment Sealing: Provides waterproof and dustproof sealing for TVs, CRT displays, power supplies, and communication devices, ensuring IP-rated protection.
- Structural Bonding: Bonds metals (e.g., aluminum, stainless steel), plastics (PC, ABS), glass, and ceramics in applications requiring flame-retardant properties.
- Thermal Management: Conducts heat efficiently (0.6W/m·K) to dissipate thermal energy from high-power components like CPUs and power modules.
Product features
Non-Corrosive Curing: Dealcoholized mechanism eliminates metal oxidation risks, safe for copper, aluminum, and alloy surfaces.
Exceptional Adhesion: Bonds tenaciously to diverse substrates without primers, reducing pre-treatment steps and costs.
Superior Dielectric Properties: Maintains stable insulation (≥16kV/mm) in high-voltage environments, critical for electrical safety.
Thermal Conductivity: 0.6W/m·K thermal conductivity manages heat buildup in compact electronic designs.
Wide Temperature Stability: Remains flexible and functional from -40°C to 150°C, suitable for harsh environmental conditions.
Weather Resistance: Withstands UV, moisture, and ozone exposure, ensuring long-term reliability in outdoor or industrial setups.
