Product Overview
Our Electronic Potting for Resonant Cavity LEDs is a professional Silicone Potting Compound developed for the encapsulation, sealing, heat dissipation and protection of Resonant Cavity LEDs (RCLEDs). As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for RCLED’s core needs—ultra-low optical loss, narrow spectral linewidth and high brightness stability. Unlike ordinary potting silicones, it maintains ultra-low optical loss after curing, does not interfere with RCLED’s narrow-spectrum emission, efficiently dissipates heat to avoid brightness attenuation, resists corrosion and ozone, and has excellent adhesion to PC, PMMA, PCB and metals, effectively protecting RCLED chips and welding wires, ensuring long-term stable luminous performance for procurement partners.
Key Features & Advantages
- Ultra-Low Optical Loss & Narrow Spectral Compatibility: Ultra-low optical loss (≤0.08%) after curing, ensuring no obstruction to RCLED’s narrow-spectrum transmission and maintaining stable spectral linewidth and brightness; high transparency and uniform light transmittance, avoiding spectral broadening or distortion, which is critical for RCLED’s application in high-precision optical communication and sensing.
- Superior Heat Dissipation & Temperature Adaptability: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance; integrated thermally conductive potting compound properties accelerate heat dissipation of RCLED chips, avoiding overheating-induced brightness decay and spectral drift, extending service life; absorbs internal stress from temperature cycles, protecting RCLED chips and welding wires from damage.
- Ultra-High Insulation & Anti-Vibration: Ultra-strong insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), preventing short circuits and ensuring safe operation; excellent anti-vibration and shock-resistant effects, protecting RCLEDs from mechanical damage during transportation and use; waterproof, moisture-proof and dust-proof, adapting to harsh industrial and optical application environments.
- Strong Adhesion & Easy Operation: Excellent adhesion to PC (electronic insulation board), PMMA (acrylic), PCB and metals (aluminum, copper, stainless steel), forming a tight seal without detachment; two-component design, easy to mix evenly, optional vacuum defoaming (0.01MPa for 3 minutes), supports room temperature or heated curing, full curing in 24 hours, suitable for batch RCLED production.
- High Stability & Dual-Formula Options: Available in high-purity addition curing silicone (low volatility, non-toxic, high stability) and enhanced thermally conductive potting compound (for high-power RCLEDs), meeting different power and application needs; low volatility, high strength, no stratification after long-term storage (stir before use without affecting performance); mixed glue can be used up at one time, reducing waste and procurement costs.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A in its container to mix the settled filler evenly, and shake Component B thoroughly to ensure uniform consistency, avoiding affecting curing effect, optical loss and adhesion, which is crucial for RCLED’s spectral and luminous performance.
- Mixing: Mix Component A and Component B according to the specified weight ratio (customizable), stir slowly and evenly to avoid generating air bubbles, which may affect optical loss, heat dissipation and sealing performance of RCLEDs.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.01MPa for 3 minutes to completely eliminate air bubbles, then pour it into RCLED packaging molds or casings.
- Curing: Place the encapsulated RCLED at room temperature for curing or heat to accelerate curing; enter the next process after basic curing, and full curing takes 24 hours. Note: Environment temperature and humidity significantly affect curing speed and final performance.
