Product Features & Advantages
1. Traditional Texture Replication: Superior fluidity penetrates fine gaps, perfectly restoring the delicate textures, carvings, and classic patterns of traditional gypsum crafts, retaining the original artistic charm.
2. High Durability: High tensile and tear resistance, supporting 50~80 mold turns, reducing mold replacement frequency and lowering production costs for batch gypsum production.
3. Gypsum-Adaptable: Cured silicone has excellent release performance, preventing gypsum adhesion and ensuring smooth demolding without damaging the gypsum product surface.
4. Safe & Compliant: FDA-certified Food grade mold silicone, non-toxic, odorless, and environmentally friendly, complying with global industrial and craft safety standards. 5. Flexible Operation: Room temperature or heat curable, simple 1:1 mixing ratio, adapting to traditional manual molding and semi-automatic mass production.
6. Full Customization: Color, viscosity, operating time, and curing time can be tailored to match different traditional gypsum molding processes and craft requirements.
How to Use
1. Mix Part A and Part B in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until the mixture is uniform and free of streaks or air bubbles.
2. Perform vacuum degassing on the mixed silicone for 2~5 minutes; adjust time according to silicone viscosity, weight, and vacuum strength to eliminate all bubbles.
3. Pour the degassed silicone slowly into the traditional gypsum master mold frame, ensuring full coverage of the master model’s textures and patterns.
4. Cure at room temperature (4~5 hours) or heat (80~120℃ for tens of minutes) until fully set and firm.
5. Demold gently, clean the silicone mold, and it’s ready for traditional gypsum casting, ensuring smooth demolding and intact product details.
