Step-by-Step Usage Guide
1. Prepare a clean, dust-free environment to ensure high-purity performance and mold clarity.
2. Mix Part A and Part B at a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until fully blended and bubble-free.
3. Perform vacuum degassing for 2~5 minutes (adjust based on viscosity/weight) to remove trapped air, avoiding mold defects.
4. Pour the degassed silicone slowly into craft master molds, ensuring full coverage of all fine details.
5. Cure at 25℃ for 4~5 hours, or accelerate at 80~120℃ for faster turnaround; post-cure enhances durability and transparency.
6. Store unused silicone in sealed containers indoors, avoid sunlight/rain, use within 10 months; keep away from N/P/S compounds to prevent curing failure.
