Product Description

1.Description of rtv 2 molding silicone rubber mold making for artificial stone

G830 Silicone rubber is addition cure silicone rubber for mold making and silicone products. The silicone rubber will be cured under room temperature and can be cured fastly by heating, It’s two-components liquid silicone rubber , the mixing ratio is 1:1 . It has an exceptional fluidity and good operability.Especially ,the platinum cure silicone rubber has a lower shrinkage,higher temperature resistance and it is food grade.

G830 is suitable to make mold for the product with moderate or big size.

5.Operating instructions of 1:1 silicone rubber mould making for artificial stone

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. 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.

 

Notice of Addition cure silicone rubber.

G830 is platinum cure silicone , which is very easy to cause cure inhibition , so please do remember thoroughly clean the model and tool before operation . Besides , please avoid the condensation silicone rubber (100:2) contact or mix with the following material , otherwise the silicone won’t be cured :

1. Liquid condensation silicone ( condensation silicone not completely cured or organic tin compounds )

2. Sulphur, sulfide and sulfur rubber materials.

3. Amine compounds as well as contains the amine materials.

4.  impurity, organic tin catalyst, acid, alkaline and other organisms containing sulfur, phosphorus and nitrogen will influence the vulcanization of the silicon rubber
