The power module is exposed to harsh environments such as high temperature, humidity, and vibration for a long time. Choosing a suitable power sealing adhesive is the key to ensuring the stable operation of the product!
✅ Why do we need to perform potting to power supply?
✔ Improve electrical insulation performance to prevent breakdown and short circuit
✔ Moisture resistant and waterproof, extending the service life of the power supply
✔ Anti vibration, high temperature resistance, suitable for complex working environments
✔ Improve the mechanical strength of the module and prevent component loosening
🔧 Recommended Common potting material:
Epoxy sealant: high hardness, high insulation, suitable for adapters and power drivers
Organic silicone sealant: good flexibility, high and low temperature resistance, suitable for outdoor power equipment
Polyurethane sealant: soft and impact resistant, suitable for high humidity and high salt spray environments
【 Recommended Product 】 EP 1712 Epoxy Power supply potting material
EP 1712A/B is a two-component solvent-free ambient temperature curing epoxy potting material. After mixing, it has moderate flowability, certain leak proof characteristics, and a wide range of adhesiveness.
The cured product meets UL 94V-0 flame retardancy.
