Introduction of RTV Silicone for Gypsum Moulding 

 

RTV Silicone for Gypsum Moulding is a kind of two-component material, that is the silicone is made up of Part A base silicone and Part B CA30 curing agent. The mixed Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction,and the become a silicone mold that can be used for objects reproduction.These silicone molds can be cast into different material for your target objects.The pouring material can be plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...

Applications of RTV Silicone for Moulding 

  

RTV silicone can be applied in many objects mold making, since RTV 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 Silicone can be used for artificial stone moldmaking.For example RTV2030,RTV2066 and RTV2088 silicone .

  

RTV silicone can be appliied in candle and soap moldmaking, such as RTV215 and RTV218 silicone .

  

RTV silicone can be used for plaster moldmaking, such as RTV2025,RTV2028 and RTV2030 silicone .

  

RTV silicone can be applied in the field of shoe sole moldmaking, for example, RTV3010 and RTV3015 silicone .

  

RTV silicone can be used for prototyping and electronic potting.

  

RTV Silicone for Gypsum Moulding is suitable for the reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. Etc.

 

 

 Instructions for Making Gypsum Silicone Moulds 

 

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.

  

Shortage of RTV Silicone for Gypsum Moulding 

  

When the Silicone 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 can be use again, no influence for other performance.

  

FOQ of RTV Silione for Molding 

  

Why does the RTV liquid silicone rubber for molding have few mold making times?

 

The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products
