Transparent Liquid Silicone Gel for Silicone Sponge

الوصف

1.Applications of silicone gel

It is a food grade liquid silicone rubber, it feels like jelly, so it also called "jelly silicone rubber".
It is a newly insulating material silicon of silicon compounds. It can cure at room temperature or by heating, no corrosion and little shrinkage.
Standard color is transparent, but it can also be blue, red, green or else. it has good fluidity and excellent elasticity with food grade, which can be used for sealing and pouring of various electronic components, and then forming insulation system and silicone breast.
2.Characteristics  of silicone gel

High transparency. 
High fluidity, high curing rate.
Pressure release. 
Shock absorption. 
Multiple density    

3.Operating instructions of silicone gel

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 ratio1:1 (part A:part B=1:1) ,mix the silicone rubber and catalyst evenly. 

*Notes: Molding silicon rubber is a kind of flowing liquid and it contains two parts. 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. Whats 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.
