How to Use (Step-by-Step)
1. Mix Part A and Part B of the high grade liquid silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free (critical for high-grade mold precision).
2. Vacuum degas the mixture for 2~5 minutes (time varies by viscosity) to eliminate bubbles that affect mold appearance and durability.
3. Slowly pour the degassed silicone into the master mold, leveraging its excellent fluidity to ensure full coverage of all intricate details.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing, fitting high-grade mold production timelines.
5. Gently demold the cured silicone mold, clean before reuse; store unused silicone sealed indoors, away from sunlight and rain to preserve its high-grade performance.
