Unlike condensation-cure silicone systems, addition curing silicone uses a platinum catalyst to initiate crosslinking. This fundamental difference in chemistry delivers several critical advantages:
• Near-zero shrinkage (<0.1%) — Every detail captured in the master pattern is faithfully reproduced, even after hundreds of casting cycles • No byproducts during curing — The process is clean, odorless, and safe for food-contact and skin-contact applications • Superior tear strength — Molds last longer, reducing replacement costs and production downtime • Wide temperature tolerance — From -60°C to 200°C, the material performs consistently in any production environment • Excellent chemical resistance — Compatible with gypsum, cement, GRC, polyurethane, epoxy resin, wax, and more
Hong Ye Silicone's Product Range
Hong Ye Silicone offers two main series of addition curing silicone rubber for mold making:
- E Series (Translucent) — Models HY-E615 through HY-E650, available in 15 to 50 Shore A hardness. Mixing ratios of 1:1 or 10:1 by weight provide flexibility for different workflow requirements.
- Q Series (Fully Transparent) — Ultra-clear formulation designed for applications where visual inspection of the mold interior is important, or where optical-level clarity is needed in the final cast product.
Both series feature adjustable pot life (30-60 minutes) and curing time (3-6 hours at room temperature), with the option to accelerate curing using heat.
