How to Use (Step-by-Step Guide)
1. Ensure operating environment is clean and dry (critical for molding precision and heat resistance).
2. Mix Part A and Part B of the heat-resistant silicone in a 1:1 weight ratio, stirring thoroughly in an irregular direction for 2~3 minutes until uniform and bubble-free.
3. Perform vacuum degassing for 2~5 minutes (time varies by viscosity) to eliminate bubbles, avoiding molding defects.
4. Pour the degassed silicone into mold masters, leveraging good fluidity to fill all precise details.
5. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing; for high-temperature molding scenarios, post-cure at 150℃ for 1 hour to enhance heat resistance.
6. Store unused silicone in sealed packaging, separate Part A and Part B, indoor storage away from sunlight and rain, use within 10 months; avoid contact with N, P, S-containing compounds to prevent curing failure.
