GS-C20 shoe sole mold making liquid silicone rubber  

1.Description of shoe sole mold making liquid silicone rubber

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.

5. Using instructions of shoe sole mold making liquid silicone rubber

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 evenly. 
*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 the prototype 
*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 curing time.
