Product detail:

Description of Condensation Cure Silicone Mold Making Rubber 

 

RTV2 Silicone Rubber is a kind of two-component material, and the RTV2 silicone rubber includes Part A base silicone and Part B CA30 curing agent. The 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 mold to duplicating: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...

Applications of Condensation Cure Silicone Mold Making Rubber 

  

MC RTV-2 silicone rubber for moldmaking can be applied in many objects mold making, since MC RTV-2 silicone rubber 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 RTV2030,RTV2066 and RTV2088 silicone.

 

RTV-2 silicone rubber can be appliied in candle and soap moldmaking, such as RTV215 and RTV218 silicone.

 

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

 

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

 

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

  

Instructions of Condensation Cure Silicone Mold Making Rubber 

 

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.

  

Storage of Condensation Cure Silicone Mold Making Rubber 

 

When the Silicone Mold Making 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 the stirring mill to stir  the Part A silicone for some minutes, then the silicone rubber can be use again, no influence for other performance.
