Addition silicone rubber OPERRATING INSTRUCTION:
1. Clean your products and brush a layer of release agent (detergent or soap water) on the surface of your product.
Note: The model should not have been used to make molds for tin cured silicone rubber before. Otherwise, the addition silicone will not get cured. (Use a new model to test it)
2. Enclose the product (the original model) with four plastic plates or wooden plates.
3. Mixing part A and part B with 1:1 mixing ratio and stir evenly. And get the mixture for vacuum-pumping. (If there is no vacuumizer, you can just pour the mixture slowly from the corner so that less bubbles caused)
4. Pour the mixture into the model frame.
After about 2-4 hours, when the silicone cured, get out the original model, and there you get a finished addition cured silicone mold .
