Product detail:

 Features of platinum cure silicone rubber for jewelry   

 

MC Silicone addition cure molding silicone rubber is a two component elastomer cross-linking at room temperature. The polymerization can be accelerated by heat. The silicone components are delivered as liquids, which once mixed and cured transform into a transparent, elastic and resistant material. Polymerization occurs without formation of heat.

Instructions for platinum cure silicone rubber for jewelry   

 

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.
