3. Excellent Fluidity & Operability: High fluidity allows easy pouring and full filling of complex mold details, while the 1:1 weight ratio and dual curing options make operation simple, no professional skills required.
4. Durable & Cost-Effective: High tensile and tear strength supports 70~90 mold cycles, extending mold service life and reducing replacement costs by 35%, lower than ordinary mold silicone.
5. Versatile & Customizable: Adjustable hardness adapts to diverse molds (crafts, resin, concrete, prototypes); color, operating time, and curing time can be tailored to client needs.
6. Strict Quality Control: As a standardized production enterprise, we ensure consistent batch performance, reducing mold rework rates.
How to Use (Step-by-Step)
1. Mix Part A and Part B of the High Performance Silicone for 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 mold precision.
2. Vacuum degas the mixed silicone for 2~5 minutes; adjust time based on viscosity, silicone weight, and vacuum intensity to eliminate bubbles that affect mold quality.
3. Pour the degassed silicone into the mold master, leveraging its excellent fluidity to fill all complex details.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing (customizable for mass production).
5. Gently demold the cured mold; store unused silicone sealed indoors, away from sunlight and rain, and use within 10 months.
