White RTV2 Silicone Moulding Rubber for Plaster Mold Making
Introduction of RTV-2 Silicone Rubber MCSIL-2030 Silicone Rubber is a kind of two-component material. The RTV-2 silicone rubber is made up of Part A base silicone and Part B curing agent. The Part A base silicone and Part B CA curing agent can cure at room temperature by a condensation reaction, after full cure, it become a cured silicone mold. The silicone mold can be cast the following materials for reproduction: Plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...
Characteristics of RTV-2 Silicone Rubber 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, High Casting times
5. Acid and alkali-resistance
6. Low linear shrinkage
Applications of RTV-2 Silicone Rubber RTV-2 silicone rubber for mold making can be used in the filed of reproducing cement molds, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. etc.
RTV-2 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.
RTV-2 Silicone Rubber can be used for artificial stone mold making. For example 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 plaster mold making, 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.
Procedures for RTV-2 Silicone Rubber 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.
Storage of RTV-2 Silicone Rubber When the silicone rubber is stored at or below 30C (85F) in the original unopened containers, RTV2 Silicone Base and CA30 Curing agent have a usable life of
12 months from the date of production. After 12 months, please use a stirring mill to stir the Part A silicone for some minutes, then the silicone can be use again, without any influence to the characteristics.
Package of RTV-2 Silicone Rubber 25kg per steel drum; 200kg per steel drum.
