Crafted from high-purity Silicone raw materials, it features 1:1 weight mixing ratio, low viscosity, excellent flame retardancy and insulation, curing at room or heated temperatures. It adheres well to PC, PMMA, PCB and metals, protects core FDR components, ensures stable signal transmission, complies with EU RoHS, and supports full parameter customization (around 198 characters).
Product Overview
Our Electronic Potting Flame-Retardant Silicone is specially developed for Frequency Domain Reflectometers (FDR), dedicated to encapsulating, sealing, insulating and flame-retarding FDR signal transmitters, receivers, PCB substrates, connection terminals and detection modules. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for high-precision signal detection scenarios, enhancing flame retardancy, low signal interference and environmental stability to adapt to the ultra-high-precision, safe operation requirements of FDR equipment. Compared with epoxy potting resin, it cures without exotherm, no corrosion, low shrinkage, and excellent weather resistance, ensuring long-term reliable operation of FDR components in industrial detection and laboratory environments.
Key Features & Advantages
- Excellent Flame Retardancy & Safety: High-grade flame-retardant formula, effectively preventing fire spread, meeting international flame-retardant standards, ensuring safe operation of FDR equipment in high-voltage or flammable industrial environments, reducing potential safety hazards.
- Low Signal Interference & High Detection Stability: Ultra-low dielectric loss and minimal electromagnetic interference, avoiding interference with FDR frequency signal transmission and reflection detection, ensuring accurate and stable detection data, crucial for cable fault or material property testing.
- Superior Insulation & Environmental Adaptability: High volume resistivity (≥1×10¹⁵ Ω), excellent dielectric strength (≥25 kv/m), isolating internal and external interference and static; waterproof, moisture-proof, mold-proof and dust-proof, withstanding harsh industrial and laboratory environments, non-yellowing and weather-resistant.
- Flexible Curing & Easy Operation: 1:1 weight mixing ratio, easy to proportion and stir; curable at room or heated temperatures (80℃ curing takes 4-5 hours), curing without exotherm, no corrosion, low shrinkage, fully cured in 24 hours, improving production efficiency.
- Strong Adhesion & Customizability: Excellent adhesion to PC, PMMA, PCB, aluminum, copper and other metals, ensuring tight sealing of FDR components; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity, operation time and flame-retardant level to match different FDR models.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A and Component B in their respective containers to ensure uniformity, avoiding stratification that affects flame retardancy and insulation performance.
- Precision Mixing: Strictly follow the 1:1 weight ratio of Component A to Component B, stirring slowly and evenly to ensure full integration without air bubbles that cause signal attenuation and affect detection accuracy.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.08MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of FDR components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature or heat to 80℃ to accelerate (4-5 hours at 80℃). Note: Curing effect is greatly affected by temperature; properly heat in low-temperature environments to speed up vulcanization.
