5. Using instructions of condensation mold making rtv2 silicones for gypsum board

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.
