HONG YE SILICONE Electronic Potting Silicone for Neural Recording Arrays is a high-performance two-component Addition Curing Silicone, also known as Electronic Potting Compound, Silicone Encapsulant and electronic potting gel, tailored for neural recording arrays. Crafted from high-purity Silicone raw materials, it integrates excellent biocompatibility, low signal interference, insulation, thermal conductivity and flame retardancy, cures into a solid protective layer after adding curing agent. With strong adhesion to PC, PMMA, PCB and metals (aluminum, copper, stainless steel), it protects precision neural recording components, ensures stable signal acquisition, and has customizable parameters to meet global neurotechnology procurement demands.
Product Overview
Our Electronic Potting Silicone is specialized for neural recording arrays, designed for encapsulation, sealing, filling and pressure protection of their core electronic components, signal acquisition modules and electrode connection units. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for neurotechnology scenarios, enhancing biocompatibility and low dielectric loss to avoid interfering with neural signals. It outperforms epoxy potting resin in flexibility and biocompatibility, cures at room or elevated temperatures, and ensures reliable protection for neural recording array components, extending service life and improving signal stability for neurotechnology manufacturers.
Key Features & Advantages
- Excellent Biocompatibility: Non-toxic, low-volatile formula, complying with medical-grade biocompatibility standards, no harmful substances released, safe for use with neural recording components and biological environments.
- Low Signal Interference: Ultra-low dielectric loss and stable insulation performance (volume resistivity ≥1.0×10¹⁶ Ω·cm), avoiding interference with neural signal acquisition and transmission, ensuring accurate data collection.
- Extreme Temperature Stability: Operates stably from -60℃ to 220℃, withstanding temperature fluctuations in lab and clinical environments, absorbing internal stress to protect delicate neural recording chips and welding gold wires.
- Low Volatility & Strong Adhesion: Ultra-low volatile content, no contamination to neural components; strong adhesion to PC, PMMA, PCB and various metals, ensuring tight sealing and no peeling in long-term use.
- Flexible Curing & Customizability: Addition-curing formula, supporting room-temperature or heated curing (full curing in 24 hours); as a professional Silicone Potting Compound manufacturer, we can customize hardness, viscosity and operation time to match different neural recording array models.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously to ensure uniformity, avoiding stratification which affects adhesion and signal compatibility.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly for 2-3 minutes to avoid introducing air bubbles that affect sealing and signal stability.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of neural recording array components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature or heated to accelerate, enter the next process after basic curing, and ensure 24 hours full curing. Note: Environment temperature and humidity have a significant impact on curing speed.
