How to Use (Step-by-Step)

1. Mix Part A and Part B of the precision addition curing silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free—critical for ensuring molding precision.

2. Vacuum degas the mixed silicone for 2~5 minutes; adjust time according to viscosity, weight and vacuum pressure to eliminate bubbles that affect precision.

3. Slowly pour the degassed silicone into the master mold, leveraging its excellent fluidity to fully cover all intricate details and cavities.

4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated addition curing, ensuring stable precision for molding projects.

5. Gently demold the cured mold, clean thoroughly before reuse; store unused silicone sealed indoors, away from sunlight and rain to preserve its precision performance.
