Operation of RTV molding silicone rubber for concrete baluster moulds making

1. Stir part A and part B with right mixing ratio (100:5) evenly. And get the mixture for vacuum-pumping. (If there is no vacuum machine, just mix less catalyst)

2. Clean your products and brush a layer of release agent (detergent or soap water) on your product.

After about 3-5 hours, when the silicone get cured, take out the original mold, and there is th finished silicone mould.

FAQ of RTV molding silicone rubber

What should we do when the air bubbles appeared in the process of mold making ?

To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicone rubber and curing agent evenly and then take it to vacuum chamber to deair. If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicone rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicone rubber will slow down, so, the air in the mold will be eliminated gradually to reduce the air bubbles.
