How to Use (Step-by-Step)
- Pre-Mix Uniformity: Thoroughly stir Component A and Component B in their separate containers to ensure a consistent texture. Slight stratification may occur during storage but will not affect performance if stirred evenly.
- 1:1 Weight Mixing: Combine A and B components strictly at a 1:1 weight ratio, stirring continuously for 2-3 minutes to achieve a homogeneous mixture—critical for optimal curing.
- Vacuum Defoaming: Place the mixed silicone in a vacuum chamber and degas at 0.01MPa for 3 minutes to remove air bubbles, ensuring a dense, bubble-free encapsulation that prevents insulation degradation.
- Controlled Curing: Pour the defoamed mixture into the sensor housing. Cure at room temperature for basic shaping, or apply heat to speed up the process. Monitor temperature and humidity, as they can impact the curing speed and final properties.

FAQ
Q: Will this potting silicone affect the signal transmission of underground sensors?
A: No. It has a low dielectric constant (3.0 at 1.2MHz) and high volume resistivity, which ensure it does not interfere with signal transmission or data collection, maintaining the accuracy of sensor readings.
Q: How long can this potting silicone protect sensors buried underground?
A: With proper storage and application, our product is designed to provide long-term protection, with a service life of over 15 years in typical underground environments, significantly reducing the need for frequent sensor replacements.
Q: What chemicals or substances should be avoided to prevent curing failure?
A: Strictly avoid contact with organic tin compounds, sulfur/sulfides, amine compounds, incomplete cured condensation silicone, amine-cured epoxy resin, and solder flux—these substances will inhibit curing and compromise performance.
Q: Can it be used in areas with high soil acidity or salinity?
A: Yes. It has excellent resistance to chemical media, including acids and salts, making it suitable for use in a wide range of soil conditions, from urban areas to coastal regions.
