Introduction of RTV-2 Silicone Rubber for Soap Mold Making 

 

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

5. Low linear shrinkage

 

Applications of RTV-2 Silicone Rubber for Mold Making 

    

RTV-2 silicone rubber can be applied in many objects mold making, since the RTV-2 silicone rubber has good flow ability and medium hardness, and the silicone rubber 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 rubber.

  

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

  

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

 

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

  

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

 

RTV215 and RTV218 silicone are suitable soap and candle mold making.  

 

 

Instructions for Making Soap Silicone Molds

 

1. Preparing

 

The surface of the original objects should be clean and free of loose material. If your products have thin flower patterns, and especially have porous substrates, please use a suitable mold release agent such as soap water, detergent, Vaseline or petroleum jelly.

 

2. Mixing

 

Please weigh Part A silicone base and part B CA30 Curing Agent with ratio of 100:2 into a clean container. Stir Part A base silicone thoroughly before use, then Mix Part A and Part B evenly until the curing agent completely dispersed in the silicone base. Manual or mechanical mixture can be used, but do not last much time or allow the temperature to exceed 35°C (95°F).it’s suitable to mix small quantities to ensure thorough mixture of silicone base and curing agent.

 

Note: It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mixture to completely expand and then collapse. After a further 1 to 2 minutes under vacuum, the mixture 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.

  

3. Pouring and curing

 

Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original object, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 6 hours (or faster by different mixing ratio or room temperature), we advice you de-mold after 24 hours, it is will improve the replicate times of silicone mold. 

 

 

FOQ of RTV-2 Silicone Rubber for Mold Making

 

 

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.
