Silicone Rubber for artificial stone molding

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

Features of Silicone Rubber

a.low viscosity
b.easy operation
c.long shelf life over 12 months
d.good tear strength and low shrinkage
e.curing at room temperature within 2-4hours
f.high duplication times and no deformation

4. 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.
