lower shrinkage silicone rubber for stamp concrete mold
lower shrinkage 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.
lower shrinkage 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 .
-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
