How to Use (Step-by-Step)
1. Mix Part A and Part B of the addition type mold silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free (critical for stable curing and mold precision).
2. Vacuum degas the mixture for 2~5 minutes (time varies by viscosity) to eliminate bubbles that affect mold quality.
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 different 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 addition curing performance.
