Step-by-Step Usage Guide
1. Prepare a clean, dust-free workspace to ensure mould crafting precision and product purity.
2. Mix Part A and Part B at a 1:1 weight ratio, stir evenly for 2-3 minutes until fully blended without lumps.
3. Conduct vacuum degassing for 2-5 minutes, adjust time based on silicone viscosity, weight and vacuum pressure to eliminate air bubbles.
4. Pour the mixed silicone slowly into mould frames, ensuring full coverage of all detailed structures.
5. Cure at room temperature (25℃) for 4-5 hours, or accelerate curing at 80-120℃ for rapid mould making.
6. Store unused silicone in a sealed container indoors, avoid direct sunlight and moisture, use within 10 months.
