4. RTV-2 silicone rubber for mold making discription :

 

RTV-2 silicone rubber for mold making is a kind of flowable liquid silicone, the quality has nothing to do with the color. It consists of two components. Part A is a flowable liquid silicone rubber, part B is the curing agent. Firstly, after your previous work of dealing with the original model, take some liquid silicone rubber , add 2%-3% curing agent of the amount of silicon, and mix them evenly. Then after vacuum-pumping the mixture, you can pour it into the mold frame. The silicone mold will cured in 2-4 hours.

 

And more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.
