Product Overview
Low Creepage Electronic Potting Silicone is a pourable liquid potting material. Mixed with curing agent, it cures into flexible elastomer for encapsulation, sealing and filling electronic components. This tracking suppression potting silicone features excellent adhesion and thermal stability on PC, PMMA, PCB and CPU. It shields electronics against moisture, dust and corrosion while resisting surface tracking, keeping high-voltage insulation reliable for power and industrial electronics.
Product Features
- Low creepage design provides long creepage distance protection and high surface insulation resistance.
- Tracking suppression formula resists electrical tracking on cured surfaces for high-voltage safety.
- Waterproof, dustproof, insulating, thermally conductive, shock resistant, ozone and chemical corrosion resistant.
- Wide operating temperature range -60℃~220℃, absorbs thermal cycling stress to protect chips and gold bonding wires.
- High adhesion to aluminum, copper, stainless steel, PC, PMMA, PCB and CPU; low volatile content.
How To Use
- Fully stir component A to homogenize settled fillers and shake component B before mixing.
- Mix A and B strictly following the specified weight ratio.
- Vacuum defoam the mixed compound under 0.01MPa for 3 minutes before pouring if required.
- Pour the mixture and cure at room temperature or elevated temperature. Full curing takes 24 hours; temperature and humidity affect curing speed.
Application Scenarios
This surface insulation resistance compound is widely used for encapsulation, sealing and filling of high-voltage electronic components in power supplies, industrial controllers, LED drivers and charging modules. It maintains stable insulation under humidity and contamination, reduces tracking risk and improves electrical safety for manufacturers.

FAQ
Q: What is the key advantage of Low Creepage Electronic Potting Silicone?
A: It offers high surface insulation resistance and tracking suppression for high-voltage safety.
Q: What curing type does it adopt?
A: It is addition-cure silicone, curable at room temperature or by heating.
Q: Can leftover mixed glue be stored for later use?
A: Mixed compound must be used in one batch. Unmixed raw materials need sealed storage.
Q: Is this potting silicone hazardous?
A: It is non-hazardous. Avoid contact with eyes and mouth. Rinse thoroughly with clean water upon
accidental contact.
