HONG YE SILICONE Electronic Potting Silicone for Positron Emission Tomography (PET) is a medical-grade two-componentAddition Curing Silicone, also known as Thermally Conductive Potting Compound and Silicone Encapsulant, tailored for PET equipment. Crafted from high-purity Silicone raw materials, it features 1:1 weight mixing ratio, low viscosity, flame retardancy (UL94-V0), and excellent thermal conductivity (≥0.8 W(m·K)). It cures at room or heated temperatures, with strong adhesion to PC, PP, ABS, PVC and medical-grade metals, protecting core PET components, ensuring stable operation, complying with EU RoHS, and supporting full parameter customization to meet global medical equipment procurement demands (around 198 characters).
Product Overview
Our Electronic Potting Silicone is specially developed for positron emission tomography equipment, dedicated to encapsulating, sealing, waterproofing and fixing its core electronic components, signal processing modules, power supply units and PCB boards. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for PET medical scenarios, enhancing thermal conductivity and biocompatibility to adapt to the high-precision, low-contamination requirements of medical imaging equipment. Compared with epoxy potting resin, it has better flexibility, flowability and low volatility, supports fast curing, and ensures long-term reliable protection for PET components, reducing equipment failure rates and maintenance costs for medical institutions and equipment manufacturers.
Key Features & Advantages
- Excellent Thermal Conductivity: Thermal conductivity ≥0.8 W(m·K), effectively dissipating heat generated by PET equipment operation, protecting precision electronic components from thermal damage and ensuring stable imaging performance.
- Medical-Grade Compliance: Flame retardancy up to UL94-V0, fully compliant with EU RoHS directive, non-toxic and low-volatile, no harmful substances released, avoiding contamination of medical imaging environments.
- Low Viscosity & Good Flowability: Low viscosity (500±100 cps for both components), excellent flowability, able to fully penetrate tiny gaps of PET components, ensuring tight sealing and uniform protection.
- Superior Environmental Adaptability: Operates stably from -60℃ to 220℃, with IP65 waterproof grade, excellent moisture-proof, waterproof and cold-resistant performance, extending the service life of PET equipment.
- Flexible Curing & Customizability: 1:1 weight mixing ratio, easy to operate; cures at room temperature (4-5 hours) or heated (80℃ for 20 minutes); as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity and operation time to match different PET equipment models.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A and Component B in their respective containers to ensure uniformity, avoiding stratification that affects thermal conductivity and adhesion.
- Precision Mixing: Strictly follow the 1:1 weight ratio of Component A to B, stirring slowly and evenly to ensure full integration, resulting in a mixed viscosity of 500±100 cps.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.08MPa for 5 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of PET components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature (4-5 hours) or heat to 80-100℃ for 15-20 minutes to accelerate curing. Note: Curing time may extend for thick applications; winter curing is recommended to be heated.
