5100: 1:1 Potting Material Black & Semitranslucent Fluid Silicone, 500-1500 mPa·s Viscosity, -40°C~200°C Operating Temp – Ideal for Instrumentation/Sensor Potting, Ultrasonic Radar Housing Sealing

Product Description

HUITIAN 5100 is a premium two-component addition silicone designed for demanding industrial applications. Characterised by its black fluid (Part A) and translucent fluid (Part B) formulation, it features a 1:1 mixing ratio, enabling both room temperature and heat curing. This versatile product combines fast curing with exceptional performance, making it an ideal choice for critical encapsulation and sealing needs across various industries, especially in advanced driving assistance systems.

Product Applications
HUITIAN 5100 excels in a range of applications, with its core uses including:

• Encapsulation of instrumentation components and sensors: Providing comprehensive protection such as moisture resistance, anti-fouling, corrosion resistance, shock absorption, insulation, and sealing.
• Sealing of ultrasonic radar housings in assisted driving systems: Specifically developed for scenarios like parking assistance, blind spot monitoring, and low-speed collision avoidance. It ensures stable signal transmission even in extreme environments, enhancing radar sensitivity and reliability—critical for safe and accurate vehicle perception.

Key Product Features 

• Ultra-Low Dielectric Loss for Signal Integrity
  With a dielectric constant of 2.8~3.2 and a low dielectric loss formula, it minimizes signal transmission loss to the greatest extent. This ensures clear and stable ultrasonic reflection signals, significantly enhancing the sensitivity of devices like ultrasonic radars—vital for lossless signal transmission in critical applications.
• Ultra-Wide Temperature Range for Extreme Environments
  Operating efficiently within -40°C to 200°C, it withstands harsh conditions from frigid northern winters to humid southern climates. Combined with excellent weather resistance and aging resistance, it maintains stability in urban congestion and polar environments alike, ensuring long-term performance.
• Superior Sealing with Multi-Material Compatibility
  Boasting a low viscosity of 500~1500 mPa·s, it offers high sealing grades and good fluidity. Its primer-free bonding capability ensures strong adhesion to diverse materials, including PA66, ABS, PC, metals, and glass, simplifying processes while guaranteeing reliable sealing.
• Superior Reliability and Compliance
  It meets the RoHS Directive, ensuring eco-friendliness and non-toxicity. With fast curing (especially under heating) and excellent insulation properties (volume resistivity ≥1×10¹⁴ Ω·cm, dielectric strength ≥15 kV/mm), it provides robust protection for internal components, extending service life and reframing safety boundaries.

Technical Parameters

Directions for Use

1. Before Mixing: Stir Part A and Part B thoroughly, either manually or mechanically.
2. Mixing: Accurately weigh Part A and Part B in a 1:1 ratio, place them in a clean container, and mix well.
3. Defoaming: Apply vacuum at 0.08~0.1 MPa for 2~3 minutes to remove air bubbles.
4. Potting: Complete potting within the pot life to ensure proper levelling. Ensure the substrate surface is clean and dry before potting.
5. Curing: Cures at both room temperature and under heat. For optimal curing speed and bonding strength, heating is recommended as curing performance is temperature-dependent.
