How to Use
1. Before mixing, fully stir Part A to evenly distribute settled fillers, and shake Part B thoroughly to ensure uniformity. 2. Mix Part A and Part B according to the specified weight ratio to ensure stable curing and reliable protection performance. 3. Degas if needed: put the mixed silicone into a vacuum container, degas at 0.01MPa for 3 minutes, then pour into solar charge controller components. 4. Cure at room temperature or by heating; basic curing completes before the next process, and full curing takes 24 hours (environment temperature and humidity affect curing effect).
Application Scenarios
This Electronic Potting Compound is mainly used in solar charge controllers, including residential and industrial solar charge controllers, off-grid solar system controllers, PCB boards, control modules and internal electronic sensors. It effectively protects controller electronics from rain, humidity, UV radiation and high temperature, reduces failure rates, extends service life, improves energy conversion efficiency, and lowers maintenance costs, bringing cost-saving and reliability value to global solar industry clients.
