Step-by-Step Usage Guide
1. Prepare a clean, dust-free industrial workspace to ensure silicone quality and mold precision.
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 flaws in molds/components.
4. Pour the mixed tough silicone into molds or application areas, ensuring full coverage of complex structures.
5. Cure at 25℃ for 4-5 hours, or accelerate at 80-120℃ for quick production; post-cure enhances toughness and temperature resistance.
6. Store unused silicone sealed indoors, avoid sunlight/moisture, use within 10 months to maintain performance.
