3. RTV  NEW--liquid silicone for crafts mold making discription

     RTV Silicone Rubber for plaster products molding 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.
 

4.  RTV  NEW--liquid silicone for crafts mold making   frequently asked question:

  Why does the liquid silicone rubber mold have few molding times?
The silicone rubber castine stone molds has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
