Product Description
Transparent RTV2 Tin Cure Liquid Silicone Rubber for Epoxy & Polyester Resin Molds — HN-625 A/B
HN-625 A/B is a transparent two-component RTV2 tin cure (condensation cure) liquid silicone rubber with high chemical stability and a wide temperature range of -55°C to +220°C. Cured at room temperature with a 100:2 mixing ratio, it produces precise, low-shrinkage molds — ideal for epoxy casting, polyester resin molds, and stone / gypsum construction and crafts.
Key Features
- High chemical stability — performs from -55°C to +220°C for long-term use
- Transparent appearance — clear formulation allows easy visual monitoring of mold quality
- Low shrinkage (≤0.2%) — no low-molecule release during cross-linking, high precision
- Low viscosity and good fluidity — easy pouring; cures at room temperature or with heat
- High tear strength (19.8–24.3 kN/m) for many demolding cycles and long mold life
- Waterproof and ozone resistant; non-toxic, tasteless, non-corrosive; MSDS & RoHS certified
