Introduction of RTV Silicon Rubber for Concrete Mold

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.
Characteristics of 
RTV Silicon Rubber for Concrete Mold
1. Good flow ability and long working time
2. Medium hardness
3. High tear and tensile strength
4. Easy de-mould from complex replica parts
5. Acid and alkali-resistance
6. Low linear shrinkage


Procedures of RTV Silicone Rubber for Concrete Mold

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.

Applications of 
RTV Silicon Rubber for Concrete Mold
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.

Packing of RTV 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 RTVSilicone Rubber

When the RTV-2 silicon rubber is stored at or below 30 C (85F) in the original unopened containers, Silicone Base and CA30 Curing agent have a usable life of 12 months from the date of production.

 Why we choose silicone rubber for mold making

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.

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 RTV2010 and RTV2015 silicone.
RTV-2 Silicone rubber can be used for concrete , plaster  and gypsum mold making, such as RTV2025, RTV2028 and RTV2030 silicone.
