Description for RTV Silicon Rubber for Concrete Mould Making:
Liquid silicone rubber, RTV-2 Silicone, Moulding silicones are generally named as two-part room temperature cure silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.
Characteristics of RTV Silicon Rubber for Concrete Mould Making
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
Applications of RTV Silicon Rubberfor Concrete Mould Making
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 RTV Silicon Rubber Raw Material for Concrete Mould 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 RTV Silicon Rubber for Concrete Mould Making
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 RTV Silicon Rubber for Concrete Mould Making
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 mold making. For example, MCSIL-2030, MCSIL-2066 and MCSIL-2088 silicone.
RTV-2 Silicone rubber can be applied in candle and soap mold making, such as MCSIL-215 and MCSIL-218 silicone.
RTV-2 Silicone rubber can be used for concrete, plaster and gypsum mold making, such as MCSIL-2025 and MCSIL-H25.
