5. Safe & Versatile: FDA-certified, non-toxic, odorless, compatible with resin, metal, concrete, fitting diverse casting mold scenarios.
6. Easy Operation & Customization: 1:1 mix ratio, dual curing options; fluidity, curing time and hardness can be tailored to casting mold needs.
How to Use (Step-by-Step)
1. Mix Part A and Part B of the casting silicone for mold making in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free (critical for smooth casting and mold precision).
2. Vacuum degas the mixture for 2~5 minutes (time varies by viscosity) to eliminate bubbles that affect casting quality and mold appearance.
3. Slowly pour (cast) the degassed silicone into the master mold, leveraging its excellent fluidity to ensure full coverage of all intricate details and cavities.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing, fitting casting production timelines.
5. Gently demold the cured silicone mold, clean before reuse; store unused silicone sealed indoors, away from sunlight and rain to preserve its casting performance.
Application Scenarios
This casting silicone for mold making is widely used in casting mold scenarios, including resin casting molds, rapid prototyping silicone molds, industrial Mold Silicone rubber production, metal craft casting molds, concrete and cultural stone casting molds, and precision handboard casting.
