2 part liquid silicone of silicone rubber mold for concrete statue reduplication
Application of 2 part liquid silicone of silicone rubber mold for concrete statue reduplication :
Production mold casting wax, gypsum, concrete or resins (urethane, polyester, etc. ). Applications include reproducing sculpture, architectural restoration, making candle molds, casting pewter, place couldnt pour rubber over the above etc. For make a mold by brushing (or spraying) rubber onto the model. Rubber will hold a vertical surface and will reproduce the finest detail brushed onto the model in layers until a suitable thickness is built up.

Step TWO: Take 100 G parts A and add 3G parts B and mix them evenly.
Notes: Mold making silicon rubber is a kind of flowing liquid ,it contains two parts. Part A is akind of flowing white liquid and part B is the curing agent or catalyst .Please follow the step strictly:
Weigh the two part exactly by electronic weight.
If not , for example add two much catalyst , the operation time will be too fast to operate ,which will cause inconvinience to operate .
Mix part A and part B evenly.
Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.
Step THREE: Vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.
Step FOUR: Pouring casting or Brush operation
For simple pattern products we suggest use pouring operation way , which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air .
For delicate pattern products we suggest use brushing operation way , which can copy the pattern exactly . Brushable silicone require high viscosity which won’t be easy to flow away and easy to brush .
We sugges to set the silicone mold for another 12 hours after demould before put into large
