Introduction of RTV Silicon Rubber for Concrete Casting

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 Casting

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 Silicon Rubber for Concrete Casting

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 Casting

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

PART A base Silicone: 5kg/pail, 20kg/pail, 25kg/pail or 200kg/pail.
PART B catalyst ( curing agent ): 800g/bottle, 1kg/bottle, 10kg/bottle.

Storage of RTV Silicone 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

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 moldmaking. For example MCSIL-2066 and MCSIL-2088 silicone.

RTV-2 silicone rubber can be appliied in candle and soap moldmaking, such as MCSIL-215 and MCSIL-218 silicone.

RTV-2 silicone rubber can be used for plaster moldmaking, such as MCSIL-2025, MCSIL-H25 and MCSIL-2030 silicone.

RTV-2 silicone rubber can be applied in the field of shoe sole moldmaking, for example, MCSIL-S10 and MCSIL-S15 silicone.

RTV-2 silicone rubber can be used for prototyping and electronic potting.
