How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A to mix the settled filler evenly, and shake Component B thoroughly to ensure uniform consistency, avoiding affecting the curing effect and adhesion to silver mica capacitors and silver mica chips.
- Mixing: Mix Component A and Component B according to the specified weight ratio (customizable), stir slowly and evenly to avoid generating air bubbles, which will affect the insulation and sealing performance, and prevent damage to delicate silver mica chips.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.01MPa for 3 minutes to completely eliminate air bubbles, then it can be used for pouring.
- Curing: Pour the degassed potting compound into the silver mica capacitor packaging mold, place it at room temperature for curing or heat to accelerate curing; after basic curing, proceed to the next process, and full curing takes 24 hours. Note: Environment temperature and humidity significantly affect curing speed.
