Differences between the condensation and addition cure Silicone rubber rtv for soap mold:
1, The difference between addition cure silicone and condensation cure silicone.
The mixing ratio of A and B is different
The mixing ratio of condensation cure silicone is normally 100:2~100:5, some from European and USA is 10:1.
The mixing ratio of addition silicone is normally 1:1, 10:1, 9:1
2, Addition cure silicone is odorless, environmental friendly, and food grade. So the raw material of addition cure silicone is more expensive than that of condensation cure silicone, so does the price.
3, Addition silicone has a wider range of applications, such as used for food, life casting, tire mold casting and so on.
4, The shrinkage of condensation cure silicone is low, about 0.3%; While addition cure silicone is with lower shrinkage, about 0.1%.
5. Addition cure silicone can be transparent, even high transparent, of course the price is more expensive.
However, condensation cure silicone can be white or other colors too, but no transparent.
6, Temperature resistance is different, addition cure silicone is better than condensation cure silicone in this performance.
Condensation cure silicone: 100-150C
Addition cure silicone: 150-220C

Operation:
(1) prepare the original molds:
Make sure your original molds perfect. fix it on a board. And fix the original mold on a board, then used four piece of board to enclose the original molds.
(2) Weight part A & part B according to the mix ratio recommended:
Weighting two parts in Electronic scale with mix ratio 100:2 or 100:5.
Eg: Take 100g part A and 2g part B
(3) Stirring evenly
Remember to mix part A and part B evenly, otherwise the silicon rubber will be partly solidified and bring problems in your final operation. What's more, the finished molds will meet a short life.All of these will cause a waste of silicon rubber.
(4)Vacuum pumping
For releasing the air bubbles, after mixing evenly, put the mixture in to vacuum pumping for 3-5 minutes, without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.
(5) Pouring or Brushing
Pouring:Pouring the silicone rubber to the frame from a corner, make the silicone rubber flow to the frame smooth.After 3-5 hours later, can demould the silicone mold,
It's will be better for mold to demould after 24 hours
Brushing:
A: Evenly brush the first layer of mixed silicon rubber on the model. Normally the first layer is brushed thinly to cover the model and the clay, so it should not be too thick
B: Brush the second layer of silicon rubber till the first one is cured. Normally the second layer should be 3-5mm, Cover a gauze or cloth on it when the second cross linking reaction goes on, and use a brush pen or a brush to avoid any interstices. Evenly brush the third layer of mixed silicon rubber on the gauze or cloth. This step will longer the mold using age, tear-strength, tension strength and duplication times.
C: Outer molding
Way 1: Make a square frame with four pieces of wooden boards, and make sure the wooden boards are fixed firmly, then pour the mixed liquid plaster into the frame. Shave the plaster-made outer mold with a scraper when the plaster is going to cured.
Way 2: brushing resin on the surface after silicone mold, Cover a gauze or cloth on it, then brushing the resin again. Repeat the operation for 2-3 times
