USING INSTRUCTIONS for cheap liquid molding silicone for architecture concrete products
Step 1: prepare the original molds: you must make sure your original molds perfect.
fix it on a board. And fix the original mold on a board , then used four piece of board to
enclose the original molds .
Step 2: Take 100 parts A and add 3 parts B and mix the silicone rubber and curing agent 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 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 3: 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 4: Pouring cast
It is suitable for simple products with the smooth surface. Without any mold lines,
which helps you save time and is easy for operation Evenly and slowly perfuse the mixed silicone
rubber into the square frame. After the cross linking reaction and the silicone rubber turns dry, y
ou can take the products out. Thus, the mold has been done.
