Platinum cured moulding silicone rubber
HY- E625 addition molding silicone could be mainly used for making concrete stones, precision molds, PU molds, for life casting, fabric finishing,shoe insoles making, seal for electronic components and solar circuit board, trademark decoration. etc.
HY-E625 addition molding silicone is generally named two-components silicone rubber, Part A is a flowable liquid, part B is the curing agent. It features an exceptional fluidity and good operability. The mixing ratio is 1:1, mainly be suitable for making molds application.

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 .
