Detailed

Mainly application of Silicone Rubber

Silicone Rubber is a two part silicone rubber and curing with tin catalyst. As with a low viscosity, high strength and excellent duplication times, it's widely used for:

for plaster decoration duplication,

for gypsum sculpture reproduction,

for duplicating resin product with fine details,

for PU resin reproduction,

for wax molding,

for stone duplication ,

for epoxy moulds,

for pacrylic moulding,

for reproducing polyester craft

Silicone Rubber for artificial stone molding

Silicone Rubber for artificial 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.
