Safe & Compliant: FDA, RoHS certified, non-toxic, odorless, meeting global safety standards, ideal for food grade mold silicone production and delicate flexible mold scenarios.
4. Excellent Fluidity & Detail Replication: High fluidity fills intricate mold details, even for irregular shapes, ensuring clear, precise mold replication, suitable for Rapid prototyping silicone and complex craft molds. 5. Easy Operation & Customization: 1:1 weight ratio for simple mixing, dual curing options; flexibility (hardness), color, and curing time can be tailored to specific molding needs.
6. Durable & Cost-Effective: High tensile and tear strength, supporting 70~90 mold cycles, extending service life and reducing replacement costs by 35% for purchasers.
How to Use (Step-by-Step for Flexible Mould Making)
1. Mix Part A and Part B of Flexible Mold Making Silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for consistent flexibility.
2. Perform vacuum degassing for 2~5 minutes; adjust time based on silicone viscosity, weight, and vacuum intensity to eliminate bubbles affecting mold quality.
3. Pour the degassed silicone into the irregular or complex mold master, leveraging its excellent fluidity to fill all details and curves.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing to retain optimal flexibility.
5. Store unused silicone in sealed packaging, indoor storage away from sunlight and rain, and use within 10 months to maintain its flexible performance.
