HONG YE SILICONE Waterproof & Insulating Electronic Potting Compound for Distributed Acoustic Sensing (DAS) is a high-reliability two-component RTV 2 Silicone Rubber, also known as Silicone Encapsulant and electronic Potting Compound, tailored for DAS equipment. Crafted from high-purity Silicone raw materials, it features 1:1 weight mixing ratio, low viscosity, UL94-V1 flame retardancy, and rapid room-temperature curing. It has excellent waterproof and insulating performance, adheres well to PC, ABS, PVC and metals, protects DAS core components, complies with EU RoHS, and supports full parameter customization (around 198 characters).
Product Overview
Our Waterproof & Insulating Electronic Potting Compound is specially developed for Distributed Acoustic Sensing systems, dedicated to encapsulating, sealing, insulating and protecting DAS sensors, signal transmitters, control modules and PCB boards. As a leading manufacturer of liquid silicone and RTV mold silicone, we optimize the formula for outdoor, harsh environment DAS working scenarios, enhancing waterproof, insulation and anti-interference performance to adapt to the long-term outdoor operation requirements of DAS. Compared with epoxy potting resin, it has excellent flexibility, no cracking under temperature changes, and effectively prevents moisture, dust and corrosion from damaging DAS components.
Key Features & Advantages
- Superior Waterproof & Insulation: High volume resistivity (≥1.0×10¹⁶ Ω·cm), dielectric strength ≥25 kV/mm, excellent waterproof sealing performance, effectively isolating moisture, dust and corrosive substances, ensuring stable operation of DAS equipment in outdoor, humid and harsh environments.
- Rapid Room-Temperature Curing: Room-temperature vulcanizing (RTV) formula, initial curing in 3-5 minutes, full curing in 24 hours; no need for heating equipment, reducing production costs and improving DAS component encapsulation efficiency.
- Excellent Flame Retardancy & Safety: Meets UL94-V1 flame retardant standard, effectively preventing fire spread, adapting to outdoor and industrial DAS working environments, and ensuring operational safety of equipment and personnel.
- Strong Adhesion & Flexibility: Excellent adhesion to PC, ABS, PVC and various metals, ensuring tight sealing of DAS components; curing into a flexible rubber state, resisting vibration and temperature changes, avoiding component damage caused by external impact.
- Easy Operation & Customizability: 1:1 weight mixing ratio, low viscosity (500±100 cps) and good fluidity, easy to stir and pour; optional vacuum degassing for better performance; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity, operation time and flame retardancy to match different DAS models.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled black pigment, and shake Component B vigorously to ensure uniformity, avoiding stratification that affects waterproof 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 sealing defects.
- Degassing (Optional): After mixing, place the adhesive in a vacuum container at 0.08MPa for 3 minutes to eliminate air bubbles, then pour it into DAS components for encapsulation.
- Curing: Place the encapsulated DAS components at room temperature for curing; initial curing in 3-5 minutes (enter next process), full curing in 24 hours. Note: Environment temperature and humidity significantly affect curing speed.
Application Scenarios
