Product Overview
Our Flame-Retardant Silicone is specialized for high-temperature geothermal sensors, designed for sealing, potting and fixing their core electronic components. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula to withstand geothermal high temperatures (adapting to long-term use under high heat) and resist geothermal fluid corrosion. It outperforms epoxy potting resin in high-temperature flexibility and flame retardancy, cures at room or elevated temperatures, and ensures reliable protection for geothermal sensor PCB substrates, power modules and signal units, extending sensor service life and reducing maintenance costs. Key Features & Advantages
- Excellent High-Temperature Adaptability: Maintains elasticity in a wide temperature range, suitable for high-temperature geothermal environments, withstanding long-term operation under extreme heat without performance degradation.
- Superior Flame Retardancy & Insulation: Outstanding flame-retardant performance, meets strict fire safety standards; high dielectric strength (≥25 kv/m-1) and volume resistivity (≥1×10¹⁵ Ω) ensure safe insulation for sensor electronics.
- Environmentally Resistant: Waterproof, moisture-proof, mold-proof and dust-proof, resisting geothermal fluid corrosion, chemical media and climate aging, ensuring stable operation in humid, corrosive geothermal conditions.
- Friendly Curing Process: 1:1 weight mixing ratio, easy to operate; cures at room temperature or can be heated to accelerate, with no heat release, no corrosion and low shrinkage during curing, protecting precision sensor components.
- High Customizability & Reliability: As a professional Silicone Potting Compound manufacturer, we offer customizable hardness, viscosity and operation time; excellent adhesion to sensor substrates, ensuring long-term structural integrity.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A and B separately in their respective containers to ensure uniform distribution of fillers and avoid stratification.
- Precision Mixing: Strictly follow a 1:1 weight ratio of Component A to B, stirring evenly to ensure consistent flame retardancy and insulation performance.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.08MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into sensor component gaps.
- Curing: Cure at room temperature or heat to accelerate (80℃ for 4-5 hours); in low-temperature environments (winter), properly heat to promote vulcanization for optimal curing effect.
