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 railway track circuit electronic 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).
