Introduction of silicone material for architectural stone and paver mold making
RTV-2 (RTV meaning Room Temperature Vulcanization) products are complex materials composed of both Agent A and Agent B. Mould silicone can be flexibly used without heating or pressing. It is well fluid and resistant to high temperature or corrosion. The strength against pulling and tearing is high. And the shrinkage is small so the frequency of mould reverse is high. It is well operational and valuable in use.

Applications of moulding silicone rubber for concrete building
RTV-2 silicone rubber for mold making can be used in the filed of reproducing cement molds, concrete, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds, prototypes, furniture, sculpture and architectural elements etc.
Procedures of silicone material for architectural stone and paver mold making
1. Make sure the surface of the original is clean and free of loose material.
2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container.
3. Stir Part A base silicone before use thoroughly, as filler separation may occur upon prolonged storage.
4. Mix Part A and Part B evenly until the CA30 completely dispersed in the base.
5. Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original
6. De-mold after 24 hours, it is will improve the replicate times of silicone mold.
Packing of Tin silicone rubber
PAR A base Silicone: 5kg/pail, 20kg/pail, 25kg/pail or 200kg/pail.
PAR B catalyst ( curing agent ): 200g/bottle, 1kg/bottle, 10kg/bottle.
Storage of Tin Silicone Rubber
It is best for the mold if it can be stored in the original mold box or on a surface that will stress them the least. If left in a distorted shape for extended periods of time, the mold may not be able to return to the original state. Keep of out sunlight and in a cool, dry area if possible.
Why we choose silicone rubber for mold making
1. Economic Use
RTV silicone rubber can be applied in many objects mold making, since the RTV-2 silicone has good flow ability and medium hardness, and the silicone can cure at room temperature, thus it's a good material for duplication.
2. Versatile Application
RTV-2 Silicone rubber can be used for artificial stone mold making. For example, RTV2030, RTV2066 and RTV2088 silicone.
RTV-2 Silicone rubber can be applied in candle and soap mold making, such as RTV215 and RTV218 silicone.
RTV-2 Silicone rubber can be used for concrete, plaster and gypsum mold making, such as RTV2025, RTV2028 and RTV2030 silicone.
