How to Use (Step-by-Step)
1. Mix Part A and Part B of the High Grade Silicone for Professional Molding in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for professional molding quality.
2. Vacuum degas the mixed silicone for 2~5 minutes; adjust time according to viscosity, silicone weight, and vacuum intensity to eliminate bubbles that affect molding precision.
3. Pour the degassed silicone into the mold master, leveraging its excellent fluidity to fully fill all gaps and details for precise forming.
4. Cure at room temperature (25℃) for 4~5 hours, or heat at 80~120℃ for tens of minutes for accelerated curing; operation and curing time can be customized as needed.
5. Gently demold the cured mold, clean thoroughly before reuse; store unused silicone in a sealed state indoors, away from sunlight and rain, and use it within the 10-month shelf life.
