Easy Operation & Customization: 1:1 mix ratio, dual curing options; fluidity, operating time and curing time can be tailored to diverse casting needs.
How to Use (Step-by-Step)
1. Mix Part A and Part B of the professional liquid silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free (critical for casting precision and fluidity).
2. Vacuum degas the mixture for 2~5 minutes (time varies by viscosity) to avoid bubbles affecting casting quality and detail replication.
3. Slowly pour the degassed silicone into the casting master mold, leveraging its excellent fluidity to ensure full coverage of all intricate details.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing, fitting casting production timelines.
5. Gently demold the casting mold, clean before reuse; store unused silicone sealed indoors, away from sunlight and rain to maintain casting performance.
