RTV2 silicone rubber for concrete stacking stone veneer molds
 
Product Description

1.Description of RTV2 silicone rubber for concrete stacking stone veneer molds

C-828 silicone rubber is condensation cure silicone for mold making.It is a kind of two-component liquid silicone .which features an excelent fluidity and good operability. The RTV-2 silicone is made up of Part A base silicone and Part B curing agent (CA). The Part A base silicone and Part B curing agent (CA) can cure at room temperature by a condensation reaction, after full cure, it becomes a cured silicone mold.

5. Using instructions of RTV2 silicone rubber for concrete stacking stone veneer molds

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.
