Description:
Mold silicone rubber is a two-component silicone rubber at room temperature (RTV).        Component A contains a crosslinking agent, and component B contains a catalyst.        Mixing the two forms a flexible and elastic silicone mold.    

Nature:
1. Good chemical stability, non-toxic and non-corrosive
2. Good fluidity for automatic mold filling
3. Controllable vulcanization at room temperature and normal pressure
4. Good demouldability
5. Strong simulation and realistic decoration
6. Fast mold making, mold can be ready within 20h    

Operation Method:
1. Stir silicone and curing agent evenly (Example: 100g silicone + 2-3g curing agent).
2. Vacuum to remove air bubbles (≤10 mins).
3. Apply silicone evenly on product, use gauze/weft cloth to reinforce if needed.
4. Create outer mold using rubber sheets, wooden boards, resin, or fiberglass.
5. For simple products, pour vacuumed silicone directly; soft silicone recommended for easy demolding.    

Use:
Suitable for molds of cement products, cultural stones, sandstone reliefs, resin crafts, tire molds, etc.    

Instructions:
Read the user guide before starting.
Use in a ventilated area. Wear safety glasses, long sleeves, and vinyl gloves.
Store and use material at room temperature (23°C).
Premix Parts A & B thoroughly.
Apply release agent if needed.
Pour, cure, and handle silicone properly.
Mold performance depends on usage; clean and store molds on a level surface in a cool, dry environment.
