Liquid silicone rubber for small crafts mold making
Descriptions of Liquid silicone rubber for small crafts mold making :
625 silicon is generally named two-components silicone
rubber, Part A and part B. It features an exceptional fluidity and good operability.
Applications of Liquid silicone rubber for small crafts mold making :
RTV-2 silicon rubber of mold making for resin crafts could be mainly used for making concrete
Stones mold , jewelry mold , statue mold, artificial craft mold, wax molds, PU molds, resin molds, gypsum casting, candle molding and prototyping etc.
Advantages of Liquid silicone rubber for small crafts mold making:
* low shrinkage (less than 0.3% )
*high tensile and tear strength with high copy times
*good fluidity easy for pouring operation ( in round 10000 cps )

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 100:3 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 .
