Descriptions for RTV-2 Silicone rubber

RTV-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...

Applications for RTV-2 silicone rubber

Silicone rubber molds,Brushable RTV-2 molding silicone rubber, RTV-2 mold making rubbers are suited for reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. etc.

Applications for RTV-2 silicone rubber
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-S20 and MCSIL-S25 silicone.RTV-2 silicone rubber can be used for prototyping and electronic potting.

Datasheet for RTV-2 silicone rubber

Storage for RTV-2 silicone rubber

When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, Silicone base and Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.

Using Instruction 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.
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.

Packaging for RTV-2 silicone rubber

Part A base silicone: 5kg, 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 250g, 800g/bottle, 1kg/bottle
