Description of RTV2 Silicone Rubber 

 

RTV2 Silicone Rubber is a kind of  two-component material, and the silicone 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. The materials can be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...

 

Features of RTV2 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 RTV2 Silicone Rubber 

    

RTV2 Silicone Rubber is 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.

  

Instructions for Making 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.
