3. Extreme temperature adaptability: Operates stably from -60℃ to 220℃, absorbs thermal cycle stress, protects detector chips and welding gold wires, avoiding sensitivity loss due to temperature changes.
4. High stability & low interference: Low volatility, high strength and strong adhesion, no harmful volatiles, not interfering with smoke detector sensors’ sensitivity, ensuring accurate smoke detection.
5. Easy operation & customizable: Available in addition and condensation curing types; simple mixing and defoaming process, room-temperature or加温 curing optional; hardness, viscosity and operating time fully customizable to match detector precision components.
Technical Specifications
This electronic potting silicone is made of high-quality silicone raw materials, liquid before curing, curing into a dense protective layer after adding hardener. It features temperature resistance from -60℃ to 220℃, excellent insulation, thermal conductivity and flame retardancy. As an addition curing product, it can be cured at room or elevated temperature, with full curing in 24 hours (environment temperature and humidity affect curing speed). Defoaming at 0.01MPa for 3 minutes is recommended; all key parameters (hardness, viscosity, operating time) are customizable to match smoke detector requirements.
Application Scenarios
Widely applied in encapsulation and protection of electronic components in various smoke detectors, including photoelectric smoke detectors, ionization smoke detectors, wireless smoke detectors and industrial-grade smoke alarms. It protects detector PCBs, sensors, power modules, signal chips and connection ports from moisture, dust, corrosion and temperature changes, ensuring sensitive and accurate smoke detection in homes, offices, factories, shopping malls and other public places.
Core Value for Buyers
1. Ensure detection sensitivity: Low volatility and stable performance do not interfere with sensor operation, ensuring smoke detectors respond quickly and accurately, enhancing product safety credibility.
2. Extend service life: Comprehensive protection against moisture, dust and temperature damage reduces detector failure rate, lowering after-sales maintenance and replacement costs.
3. Meet safety standards: Complies with international fire safety certifications and flame retardant standards, avoiding trade barriers, suitable for global smoke detector markets.
4. Improve production efficiency: Simple operation and flexible curing mode match automated production lines, shortening production cycles and reducing production costs.
How to Use
1. Pre-mixing: Fully stir Component A to mix settled fillers evenly, and shake Component B (hardener) thoroughly before use; stir evenly if layered after long storage (no impact on performance).
2. Mixing: Stir Component A and B in the specified weight ratio until fully fused, avoiding uneven mixing that affects protection and sensitivity.
3. Defoaming: Put mixed glue into a vacuum container, defoam at 0.01MPa for 3 minutes, then proceed to potting to avoid bubbles affecting sealing and detector performance.
4. Potting & curing: Pour defoamed glue into smoke detector electronic components, cure at room or elevated temperature; enter next process after basic curing, full curing in 24 hours.
