5:1 Epoxy Resin Potting Waterproof Black Epoxy Potting Compound For Sensor PCB Transformer

Description of Epoxy Potting Compound

Epoxy potting compound is a liquid encapsulant based on epoxy resin, formulated with functional additives and curing agents. It is primarily used for insulation potting, moisture-proof sealing, and protection of electronic components. Once cured, it forms a rigid, high-hardness insulator.

Application of epoxy resin potting:

Applications Across Electronics, Electrical, Automotive & New Energy:
  • Power Modules: Potting and thermal management for transformers, chargers, and inverters.
  • Sensors: Waterproof sealing for automotive sensors and industrial probes.
  • PCBs: Security, corrosion resistance, and mechanical reinforcement for sensitive components.

How to use epoxy potting compound:

1. Prepare – Ensure the component is clean and dry. Stir Part A (resin) thoroughly before use.

2. Mix by Weight – Use a precise scale. The ratio 5:1 is by weight, not volume. Example: 500g Part A + 100g Part B.

3. Stir Gently – Mix slowly in one direction for 3–5 minutes. Avoid fast stirring to prevent air bubbles.

4. Remove Bubbles (Critical) – Best: use a vacuum chamber (3–5 min). Alternative: let the mix sit for 15–30 minutes to allow bubbles to rise.

5. Pour Slowly – Fill the component in one go or in two layers (recommended) to reduce voids.

6. Cure – At 25°C (77°F), allow 24 hours. For faster results, cure at 60–80°C (140–176°F) for 2–4 hours.
