Ultra Soft Repairable Silicone Gel 1:1 Transparent Sensor Potting for Flow Meter Junction Box Waterproof Encapsulation

Ultra Soft Repairable Silicone Gel for Flow Meter Junction Box and Sensor Potting

This two-component 1:1 silicone gel is a premium soft encapsulation material based on a polysiloxane structure. Upon mixing, it cures at room temperature or under heat to form an ultra-soft, jelly-like elastic gel with exceptional flexibility and resilience. It effectively cushions sensitive electronic components against shocks and vibration while maintaining stable performance over extended periods.

Key Features

• Ultra Soft & Low Stress: Shore A 0-10 hardness minimizes stress on delicate components, solder joints and wire bonds, ideal for sensor and load cell protection.
• Repairable / Reworkable: The cured gel is easily peeled off for component repair and replacement, significantly reducing maintenance cost of flow meters and junction boxes.
• Shockproof & Vibration Damping: Exceptional cushioning absorbs external impacts and mechanical vibration, protecting precision instruments in the field.
• Waterproof & Moisture-proof: Forms a seamless protective seal against water ingress, humidity and condensation for outdoor electronic enclosures.
• High Transparency: Excellent light transmittance for optical sensors, LED packaging and visual inspection of encapsulated components.
• High Electrical Insulation: Strong resistance to electrical currents prevents short circuits and leakage in sensitive circuits.
• Wide Temperature Stability: Functions reliably from -50°C to +200°C for demanding industrial environments.
