Key Features
- Near-Zero Shrinkage — ≤0.1% shrinkage guarantees precise dimensional replication, ideal for high-volume standardized production
- High Tear Strength — ≥20 kN/m extends mold service life and reduces per-unit production cost
- Platinum Catalysis — odorless, non-toxic, FDA food-contact certified, safe and eco-friendly
- Wide Temperature Range — stable performance from -60°C to 200°C, adaptable to diverse production environments
- Excellent Flowability — 16,000–20,000 cps viscosity with self-leveling behavior captures fine surface details
- Chemical Resistance — compatible with polyurethane, epoxy resin, cement, gypsum, and wax without reaction
- Flexible Mix Ratio — supports both 1:1 and 10:1 (Part A:B by weight) to suit different process needs
