3. Safe & High-Purity: FDA-certified, non-toxic, odorless, with high-purity raw materials and strict quality control, complying with global safety standards for high-quality mold production.
4. Excellent Precision & Fluidity: High fluidity allows full filling of complex mold details, replicating intricate patterns with high accuracy, reducing rework rates for high-quality molds.
5. Easy Operation & Versatile: 1:1 weight ratio for simple mixing, dual curing options, no professional skills required; adaptable to diverse high-quality molds (crafts, industry, prototypes).
6. Fully Customizable: Hardness, color, operating time, and curing time can be tailored to meet high-quality mold requirements, with one-stop technical support.
How to Use (Step-by-Step)
1. Mix Part A and Part B of the Durable Silicone for High Quality Molds in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for mold durability and 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 intricate 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 high-quality mold; store unused silicone sealed indoors, away from sunlight and rain, and use within 10 months.
Application Scenarios
