Product Overview
Our Electronic Potting for LED is a professional Silicone Potting Compound developed for the encapsulation, sealing, heat dissipation and protection of Light Emitting Diodes. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for LED’s core needs—high light transmittance, efficient heat dissipation and anti-yellowing. Unlike ordinary potting silicones, it maintains high light transmittance after curing, does not block LED light emission, efficiently dissipates heat to extend LED lifespan, resists corrosion and ozone, and has excellent adhesion to PC, PMMA, PCB and metals, effectively protecting LED chips and welding wires, ensuring long-term stable illumination for procurement partners.
Key Features & Advantages
- High Light Transmittance & Anti-Yellowing: High light transmittance (≥95%) after curing, ensuring no obstruction to LED light emission and maintaining bright, uniform illumination; special anti-yellowing formula resists UV and high temperature, avoiding discoloration over long-term use, which is critical for LED’s lighting effect and service life.
- Excellent Heat Dissipation & Temperature Adaptability: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance; good thermal conductivity accelerates heat dissipation of LED chips, avoiding overheating damage and extending LED service life; absorbs internal stress from temperature cycles, protecting LED chips and welding wires.
- Superior Protection & Insulation: Ultra-strong insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), preventing short circuits; excellent waterproof, moisture-proof and dust-proof effects, protecting LEDs from harsh environments; anti-corrosion and ozone-resistant, adapting to various application scenarios.
- 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 LED production.
- Dual-Type Options & High Stability: Available in addition curing silicone (low volatility, non-toxic) and condensation curing silicone mold rubber (cost-effective), meeting different LED production 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, light transmittance and adhesion, which is crucial for LED’s lighting 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 light transmittance, heat dissipation and sealing performance of LEDs.
- 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 LED packaging molds or casings.
- Curing: Place the encapsulated LED 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.
Application Scenarios
This specialized electronic potting compound and silicone encapsulant is mainly used for encapsulation, sealing, filling and heat dissipation protection of various LEDs.
