HONG YE SILICONE Electronic Potting Silicone for Optical Phased Array Antennas is a high-performance two-component Addition Curing Silicone, also namedelectronic Potting Compound and Silicone Encapsulant. It integrates waterproof, moisture-proof, thermal conductivity, flame retardancy and insulation, curing into a dense, low-loss protective layer after mixing with curing agent to shield core components of optical phased array antennas. Featuring ultra-low volatile content, superior adhesion to antenna-grade metals and substrates, and dual curing options, it ensures long-term reliability under complex working conditions (electromagnetic interference, temperature fluctuations), fully meeting international aerospace and communication industry standards and crafted from high-purity Silicone raw materials.
Product Overview
Our Electronic Potting Silicone is exclusively customized for optical phased array antennas, designed for encapsulation, sealing, filling and pressure protection of precision components like antenna array elements, PCB control boards, signal transmission modules and optical waveguides. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula to resist electromagnetic interference, low-temperature thermal shock (from -60℃ to 220℃) and environmental corrosion, while ensuring low signal loss. The low-viscosity liquid penetrates tiny gaps of components, cures into a flexible and robust solid, and outperforms epoxy potting resin in signal compatibility and environmental adaptability, effectively protecting antenna signal stability and service life. Key Features & Advantages
- Low Signal Loss & EMI Shielding: Excellent insulation and low dielectric loss, avoiding signal interference and attenuation, ensuring stable transmission of optical phased array antenna signals.
- Wide Temperature Tolerance: Operates stably from -60℃ to 220℃, absorbing thermal cycling stress to protect chips, welding gold wires and optical components from damage.
- Superior Environmental Adaptability: Outstanding waterproof, moisture-proof and anti-corrosion performance, resisting dust, ozone and chemical erosion, adapting to outdoor and aerospace antenna working environments.
- Dual Curing Flexibility: Available as addition andcondensation curing silicone mold rubber, supporting room-temperature or heated curing to adapt to different antenna component production lines.
- High Adhesion & Reliability: Excellent bonding strength to PC, PMMA, PCB, CPU and antenna-grade aluminum, copper, stainless steel, preventing delamination; ultra-low volatile content avoids contamination of precision optical components.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously for 2-3 minutes to ensure uniformity (critical for signal loss control).
- Precision Mixing: Strictly follow a 1:1 weight ratio of Component A to B, stirring slowly and evenly for 3 minutes to avoid introducing air bubbles that affect signal transmission.
- Degassing (Optional): Place the mixed adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate bubbles, ensuring full penetration into tiny gaps of precision antenna components.
- Curing: Pour the degassed mixture into antenna component housings; cure at room temperature for 24 hours (full solidification) or accelerate via heating (80-100℃ for 15 minutes). Note: Temperature and humidity significantly affect curing speed, maintain 40-60% humidity for optimal results.
