Product Features & Advantages
1. Deep curing capability, no restriction by product thickness.
2. FDAcertified food grade, nontoxic, odorless, safe for direct food contact.
3. Outstanding temperature resistance, maintaining stability in extreme environments.
4. Excellent fluidity for easy pouring and detailed mold replication, compatible with roomtemperature or heated curing.
5. High tensile strength and tear resistance, ensuring multiple mold releases and long service life.
6. Customizable color, operating time, and curing time to meet diverse needs.
7. Compared with condensation curing silicone mold rubber, it offers lower shrinkage and better stability.
How to Use
1. Mix Part A and Part B at 1:1 weight ratio, stir thoroughly for 23 minutes until uniform.
2. Perform vacuum defoaming for 25 minutes (adjust time based on viscosity, weight, and vacuum intensity).
3. Pour the mixed silicone into the mold frame, ensuring full coverage of the prototype.
4. Cure at room temperature (25℃) for 45 hours or heat at 80120℃ for faster curing.
5. Demold after complete curing and proceed with subsequent use.
Application Scenarios
Ideal for mold making in food processing, crafts, and simulation industries:
Food molds: Chocolate, candy, cookie, cake, jelly, and sugar art fruit molds.
Simulated food: Production of highsimulation vegetable, fruit, and dessert models.
Crafts: Handmade soap, candle molds, and other DIY creative projects.
It helps manufacturers improve production efficiency, reduce mold replacement costs, and ensure product safety, enhancing market competitiveness.
