Key Features
•Self-Adhesive Without Primer: Bonds directly to metal cores, coil windings, PCB substrates and plastic housings, eliminating primer processing steps
•Ultra-Low Viscosity: Penetrates deep into coil gaps and tight spaces around transformer windings for thorough encapsulation
•High Dielectric Strength: 25 kV/mm minimum provides reliable insulation for high-voltage transformer applications
•Thermal Management: Thermal conductivity 0.2 W/(m.K) minimum helps dissipate heat generated by power components
•1:1 Simple Mixing: Weight-based ratio reduces measurement errors and ensures consistent curing quality
•Flexible Cure Schedule: Room temperature 8 hours or rapid heat cure 20 minutes at 80C to match production pace
•UL94 V-1 Flame Retardant: Meets international safety requirements for power and industrial electronics
•Wide Temperature Range: Performs from -50C to 200C, suitable for automotive and outdoor power equipment
Available Models

FAQ
Q: Can this potting compound withstand high voltage?
A: Yes. The dielectric strength reaches 25 kV/mm minimum, providing reliable insulation for high-voltage transformer and power module applications.
Q: How do I handle air trapped in transformer windings?
A: After mixing, vacuum degas at -0.08 MPa for 3-5 minutes before pouring. The low viscosity helps the silicone flow into coil gaps and release trapped air naturally.
Q: What if I need faster curing for mass production?
A: Heat cure at 80-100C reduces curing time to approximately 20 minutes, ideal for high-volume production lines.
