How to use:
Step 1: prepare and clean the prototype.You must make sure your original molds perfect.
Step 2: Take the silicone and catalyst as the ratio1:1 (part A:part B=1:1) ,mix the silicone rubber and catalyst evenly.
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
