Step-by-Step Usage Guide
1. Prepare a clean, dust-free workspace to maintain pure silicone quality and ensure mold precision—critical for mold production.
2. Mix Part A and Part B at 1:1 weight ratio, stir thoroughly for 2-3 minutes until fully blended.
3. Perform vacuum degassing for 2-5 minutes (adjust by viscosity/weight) to remove air bubbles, avoiding mold flaws.
4. Pour the mixed pure silicone slowly into mold frames, ensuring full coverage of all details.
5. Cure at 25℃ for 4-5 hours, or accelerate at 80-120℃ for quick mold production; post-cure enhances mold durability.
6. Store unused pure silicone sealed indoors, avoid sunlight/moisture, use within 10 months to maintain purity and performance.
