1:1 Platinum cure RTV silicone rubber for cement casting
Descriptions of cement sculpture mold making tin cure silicone rubbers :
platinum liquid silicone rubber for resin sculpture mold is generally named two-components silicone rubber, Part A and part B. It features an exceptional fluidity and good operability.
The mixing ratio is 1:1,mainly be suitable for making molds application.
Applications of cement sculpture mold making tin cure silicone rubbers :
platinum liquid silicone rubber could be mainly used for food mold , such as chocolate mold , cake mold , it is also used for making concrete stones, wax molds, PU molds, resin molds, gypsum casting, candle molding .
Advantages of cement sculpture mold making tin cure silicone rubbers :
-low shrinkage (less than 0.1% )
-high tensile and tear strength with high copy times
-easy for operation (mixing ratio at 1:1 /10:1)
-good fluidity easy for pouring operation ( in round 10000 cps )
-it is food grade with FDA

Operations of gypsum mold silicone liquid
If the customer wants to make large building concrete products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.

1. Pls clear the model and tool totally before operation to prevent cure inhibition.
2.Weigh the two part correctly by electronic weight in two separate container .
3. Mixing the two part in 100:4 and stir part A and part B evenly in 2-3 minutes .
4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3
minutes . (If there is no vacuum machine, pls pour the mixture carefully and slowly
down the side of the mold frame so that less bubbles caused)
5. Enclose the product (the original model) with four plastic plates or wooden plates.
6. Clean your products and brush a layer of release agent(detergent or soap water) on
7. Pour the vacuumed mixture into the model frame from the side of the mold frame .
