How to Use (Step-by-Step)
1. Mix Part A and Part B of the addition curing silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free (critical for mold precision).
2. Vacuum degas the mixture for 2~5 minutes (time varies by viscosity) to avoid bubbles affecting custom mold quality.
3. Slowly pour the degassed silicone into the custom master mold, ensuring full coverage of all details.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing, fitting production timelines.
5. Gently demold the custom silicone mold, clean before reuse; store unused silicone sealed indoors, away from sunlight and rain to maintain performance.
