Descriptions of liquid slicone for molds for making plaster molding
liquid silicone rubber 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 liquid slicone for molds for making plaster molding
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 liquid slicone for molds for making plaster molding
-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

Operation instruction of silicone rubber :
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 1:1/10:1 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
your product.
7. Pour the vacuumed mixture into the model frame from the side of the mold frame .
