9661(9611W4,9661G4,9661B4,9661B12,9661W1) TDS-EN.pdf
9661 is a one-component room-temperature vulcanising (RTV) silicone potting sealant that comes in white, grey, and black paste forms. It cures through moisture absorption from the air, transforming into a flexible elastomer. This sealant is designed to meet the diverse needs of various bonding and sealing applications, offering reliable performance in different environments.
The 9661 RTV silicone potting sealant finds extensive use in the lighting industry and related fields:
- Automobile lampshade bonding and sealing: It effectively seals and bonds automobile lampshades, ensuring they are protected from external elements such as dust, water, and vibration, thus maintaining the integrity and functionality of the lamps.
- Bonding and sealing of LED bulb lamps, energy - saving lamp caps, and lamp shells: This sealant provides a strong and durable bond between these components, enhancing the stability and longevity of the lighting products.
- Terminal bonding of T8 lamps and bonding and fixation of light - emitting boards: It secures the terminals of T8 lamps and firmly fixes the light - emitting boards, ensuring proper electrical connections and structural stability.
- Neutral curing: Unlike some other sealants, it cures without releasing corrosive substances, making it safe to use with most materials. This eliminates the risk of damaging sensitive components, which is crucial in applications involving various substrates.
- Excellent adhesion: It exhibits strong adhesion to a wide range of substrates. Whether it is metal, plastic, or glass commonly used in lighting products, this sealant can form a reliable bond, ensuring long - term performance.
- Superb insulation performance: With high dielectric strength (≥16 KV/mm), dielectric constant (≥2.8), and volume resistivity (≥1.0×10¹⁵ Ω·cm), it provides excellent electrical insulation. This is vital in electrical and electronic applications, preventing short circuits and ensuring safe operation.
- Outstanding weather resistance: It can withstand harsh weather conditions such as extreme temperatures, UV radiation, and moisture. This makes it suitable for both indoor and outdoor applications, ensuring the seal remains intact over time.
- Wide working temperature range: It functions stably and remains flexible within the temperature range of - 40℃ to 150℃. This allows it to be used in environments with significant temperature fluctuations without losing its performance.
- ROHS compliant: It meets the ROHS standards, which means it is free from harmful substances such as lead, mercury, and cadmium. This makes it an environmentally friendly choice, suitable for use in products that need to comply with environmental regulations.
- Clean the surface: Thoroughly remove rust, dust, oil, and other contaminants from the surface to be bonded or sealed. A clean surface ensures proper adhesion of the sealant.
- Apply the glue: Apply the 9661 RTV silicone potting sealant onto the cleaned surface. The application amount should be appropriate to ensure sufficient coverage.
- Curing process: After applying the sealant, place the coated component in the air. At room temperature (25±2℃) and 55% relative humidity, the sealant will start to cure. It can cure to a depth of 2 - 4mm. For complete curing, it is recommended to allow it to cure for 7 days under standard conditions (25±2℃, 60±5%RH) to achieve optimal performance.
