How to Use (Step-by-Step)
1. Mix Part A and Part B of the Premium Silicone for Precision Mold Making in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for precision.
2. Vacuum degas the mixed silicone for 2~5 minutes; adjust time according to viscosity to eliminate bubbles that affect mold quality.
3. Pour the degassed silicone into the mold master, leveraging its excellent fluidity to fully fill all gaps and tiny details.
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.
