How to Use (Step-by-Step)
1. Mix Part A and Part B of the high grade mold making silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for high-precision mold making.
2. Vacuum degas the mixed silicone for 2~5 minutes; adjust time according to viscosity to eliminate bubbles that affect high-end mold quality.
3. Pour the degassed silicone into the mold master, leveraging its excellent fluidity to fully fill all gaps and details for precise mold forming.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing; cure for 24 hours before first use to extend mold life.
5. Gently demold the cured mold, clean thoroughly before reuse; store unused silicone sealed indoors, away from sunlight and rain to preserve its premium performance.
