Product Description Introduction of high quality Silicone Rubber for Sculpture Mold MakingRTV-2 is a two-component Room-Temperature-Vulcanizing (RTV-2) silicone rubber. Depending on its curing mechanism, two types of RTV-2 are available: "condensation" cure type and "addition" cure type. Generally, RTV-2 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...Specifications of MC RTV-2 Silicone RubberRoom Temperature VulcanizationEquipped with REACH certificateProfessional technician with rich experience4% catalyst offers for free of chargeFree sample is availableSilicone hardness range: 10-60 shore AHigh duplicating silicone moldsCharacteristics of high quality Silicone Rubber for Sculpture Mold Making1. Good flow ability and long working time2. Medium hardness3. High tear and tensile strength4. Easy de-mould from complex replica parts5. Acid and alkali-resistance6. Low linear shrinkageApplications of high quality Silicone Rubber for Sculpture Mold MakingRTV-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 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-S20 and MCSIL-S25 silicone. RTV-2 silicone rubber can be used for prototyping and electronic potting.Procedures of high quality Silicone Rubber for Sculpture Mold Making1. 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 original6. De-mold after 24 hours, it is will improve the replicate times of silicone mold.Note: It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.
