Product Overview
Our Electronic Potting for Snubber Circuits is a professional Silicone Potting Compound developed for the encapsulation, insulation, anti-surge and protection of Snubber Circuits. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for snubber circuits’ core needs—high insulation, low dielectric loss, anti-voltage surge and protection of circuit components. Unlike ordinary potting silicones, it effectively suppresses voltage spikes, absorbs high-temperature cycle stress, protects internal resistors, capacitors and diodes, ensures stable surge suppression performance, and brings reliable protection for procurement partners.
Key Features & Advantages
- Ultra-High Insulation & Anti-Voltage Surge: Excellent insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), effectively isolating snubber circuit components; strong anti-voltage surge capability, suppressing voltage spikes and transients, avoiding component damage, ensuring stable circuit operation and reducing failure risks.
- Superior Temperature Stability & Stress Absorption: Operates stably from -60℃ to 220℃, with excellent high and low temperature resistance; can absorb stress caused by internal high-temperature cycles and voltage surges of snubber circuits, avoiding damage to resistors, capacitors, diodes and welding points, ensuring long-term stable operation in extreme industrial environments.
- Efficient Thermal Conductivity & Heat Dissipation: Integrated Thermally Conductive Potting Compound properties, efficiently dissipate heat generated by snubber circuits during surge suppression, avoid overheating-induced component burnout or performance degradation, extend product service life and reduce maintenance costs for procurement partners.
- Strong Adhesion & Wide Compatibility: High bonding strength to PC, PMMA, PCB and metals (copper, aluminum, stainless steel), forming a tight seal without detachment; good compatibility with snubber circuit components, no corrosion to resistors, capacitors or diodes, ensuring comprehensive protection against moisture, dust and corrosion.
- Low Volatility & Customizable Parameters: Low volatility, no harmful substances released during curing, ensuring the safety of precision circuit components; cured colloid has high strength and good shock absorption, reducing damage from external vibration; parameters such as hardness, viscosity, operation time and thermal conductivity can be customized to match different circuit sizes and working conditions.
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, insulation, thermal conductivity and anti-surge performance of snubber circuits.
- 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 insulation, heat dissipation and surge suppression of internal circuit components.
- 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 snubber circuit casings, ensuring full infiltration of all components.
- Curing: Place the encapsulated snubber circuit at room temperature 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.
