Condensation Cure Silicone
Condensation‑cure silicone is tin‑catalyzed two‑component mold‑making silicone rubber. Cost‑efficient for general‑purpose reproduction molds. Ethanol will be released during cross‑linking curing process. Multiple hardness options are available.
Key Features
- Tin catalyzed system, competitive material cost
- Easy mixing & room‑temperature vulcanization
- Wide shore‑A hardness range:10A‑50A
- Good flowability for fine pattern reproduction
- Suitable for large‑volume mould production
Typical Applications
- Art sculpture, statue and craft replica molds
- Gypsum, concrete and stone casting moulds
- Low‑cost resin casting, candle molds
- Decorative architectural ornament duplication
