Product detail:

Introduction of RTV-2 Molding Silicone Rubber 

 

RTV-2 Silicone Rubber is a kind of two-component material, the RTV-2 silicone rubber consists of Part A base silicone and Part B CA30 curing agent, and Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction to become a silicone mold. These materials can be cast into the cured silicone molds to duplicating : plaster polyurethane, PU, GRC, cement, resin, polyester, wax etc...

 

Features of RTV-2 Molding 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

5. Acid and alkali-resistance

6. Low linear shrinkage

 

Applications of RTV-2 Molding Silicone Rubber 

    

RTV-2 Silicone Rubber can be used in the field of reproducing cement molding, concrete 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, RTV2030, RTV2066 and RTV2088 silicone.

 

RTV-2 Silicone rubber can be applied in candle and soap mold making, such as RTV215 and RTV218 silicone.

  

RTV-2 Silicone rubber can be used for plaster mold making, such as RTV2025, RTV2028 and RTV2030 silicone.

  

RTV-2 Silicone rubber can be applied in the field of shoe sole mold making, for example, RTV3010 and RTV3015 silicone.

  

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

  

 

Procedures for RTV-2 Molding 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.

  

Storage of RTV-2 Molding Silicone Rubber 

 

When the RTV-2 Silicone Rubber is stored at or below 30 °C(85 °F) 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 rubber can be use again, no influence for other performance.

 

Packing of RTV-2 Molding Silicone Rubber  

 

Part A base silicone: 20kg/drum, 25kg/drum or 200kg/drum

Part B CA30 Curing Agent: 0.25kg/bottle,1kg/bottle and 10kg/bottle
