GS-C20 condensation cure silicone rubber for plaster sculpture
1.Description of condensation cure silicone rubber for plaster
sculpture mould making
GS-C20 Silicone rubber is tin cure silicone rubber for mold making.
It is liquid rtv mold making silicone rubber with 20 shore A
hardness.The silicone rubber will be cured under room temperature,
It’s two-components, the mixing ratio is 100:2 . Part A is a
flowable liquid silicone , part B is the catalyst. It has an
exceptional fluidity and good operability. GS-C20 has a excellent
tear-strength and tensile strength.
GS-C20 is suitable to make silicone mold for middle or small size
plaster mould , or the plaster decoration with simple pattern.

5. Using instructions of condensation cure silicone rubber for plaster sculpture mould
Step 1: prepare and clean the prototype.
You must make sure your original molds perfect. fix the original
mold on a board , then using some assistant material(like
cardpaper) to make a frame for to surround the prototype. The frame
is no need ,if we make the mold by brushing way .
Step 2: Take the silicone and catalyst as the ratio 100:2
(silicone:catalyst=100:2) ,mix the silicone rubber and catalyst
*Notes: Molding silicon rubber is a kind of flowing liquid and it
contains two parts. Part A is a kind of flowing liquid and part B
is the curing agent. Remember to mix part A and part B evenly,
otherwise the silicon rubber will be partly solidified and this
will bring troubles for your final operation. What’s more, the
finished molds will have a short life. All of these will cause a
waste of silicon rubber.
Step 3: Vacuum pumping
After mixed the silicone evenly, it is better to release the bubble
by Vacuum pumping.
Step 4: Pouring cast or brushing cast
After released the bubble, we can pour/brush the silicone rubber on
*Notes:Please finished all the steped within the operation time .If
not it will cause cross linking reaction, and no more further steps
will be available.So,we have to pay attention to the pot life and
