clear platinum cure silicone rubber jewelry molding high quality free sample 

Description  

High transparency, two-component silicone, platinum-curing/ addition-cure type, flowable, vulcanizes at room temperature or heated temperature.

Can be used for a long time in the temperature range of - 65 ° C - 250 ° C and keep its soft and elastic properties.

Application

Suitable for mold making which request high transparency to see the mold’s inside details clearly, for example rapid prototyping, lost wax casting, jewelry molds, crystal molds and so on which also request the surface of the finished product shall be transparent and glossy.

Operation instructions

1. Mix part A and pars B evenly with 1:1 or 10:1 mixing ratio.

Notes: 1) Weigh the two parts exactly by electronic weight. For example, the operation time will be shorten after adding too much catalyst.

2) Mix part A and part B evenly. Otherwise the silicon rubber will be partly solidified which will make the finished molds meet a short life and

waste silicon rubber.

2. Vacuum pumping

Notes: 1) This step is not have to have, but it is best if there is one. It will discharge all air in the mixture successfully, so as to ensure that there will be no bubbles in the finished mold.

2) This step is less than 10 minutes. Otherwise, it Will cause cross-linking reaction, and no more further steps will be available.

3. Pouring casting

Notes: We s est to set the mold for another 12 hours after demould before put it into large production.
