How to Use (Step-by-Step)
1. Mix Part A and Part B of the Flexible Silicone for Precision Mold Production in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for maintaining mold precision.
2. Vacuum degas the mixed silicone for 2~5 minutes; adjust time based on viscosity, silicone weight, and vacuum intensity to eliminate bubbles that affect detail replication.
3. Pour the degassed silicone into the mold master slowly, leveraging its excellent fluidity to fill all intricate details. 4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing (customizable for mass precision mold production). 5. Gently demold the cured mold; store unused silicone sealed indoors, away from sunlight and rain, and use within 10 months.
