5. Using instructions of Hot Sell RTV2 Mould Liquid silicone rubber for Resin Products
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 cardboard) 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 1:1 by weight, mix the silicone rubber and catalyst evenly.

Notes: rtv silicone 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 silicone rubber will be partly solidified and this will bring troubles for your final operation. What's more, the finishes molds will have a short life. All of these will cause a waste of silicone 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 finishes all the steps 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.


1.Why does the silicone mold appear to dry outside but wet inside?
Some molding silicone rubber is a kind of condensation cure silicone rubber, which would get solidified after absorbing moisture.

While in order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.

So when the humidness is lower than 50%, this would happen.

Solution: Add 0.1% water into the silicon rubber and Stir over a low speed briefly when you use it.


2.Why the silicone mould cured incompletely?

a. Inexact mixing ratio, didn’ t weigh the part A and hardner according to the standard ;

b. The silicone and catalyst have not been mixed evenly and totally.

We should pay attention to avoid this kind of problem, otherwise there will be a waste of silicone mold.
