Product Features & Advantages
Adopting advanced additioncuring technology, this silicone outperforms condensation curing alternatives with deeper curing and lower shrinkage. Key advantages:
1. Deep curing capability, no restriction by product thickness.
2. Foodgrade, nontoxic, odorless, FDAcertified for safe food contact.
3. Extreme temperature resistance, maintaining elasticity in harsh environments.
4. Superior fluidity for easy pouring and fine detail replication; dual curing methods for flexibility.
5. High tensile and tear strength, enabling more mold releases and longer service life than ordinary silicone.
6. Fully customizable color, operating time, and curing time to meet diverse needs.
Backed by 20+ years of manufacturing experience, our product ensures stable quality and consistent performance.
How to Use
1. Mix Part A and Part B at 1:1 weight ratio, stir thoroughly for 23 minutes.
2. Perform vacuum defoaming for 25 minutes (adjust based on viscosity and vacuum intensity).
3. Pour the mixture evenly into the mold frame.
4. Cure at 25℃ for 45 hours or heat at 80120℃ for faster results.
5. Demold after full curing and start production.
Application Scenarios
This versatile silicone serves multiple industries:
Food industry: Chocolate, cake, and simulated food molds.
Crafts industry: Metal crafts and alloy car accessory molds.
