Advantage of platinum cured silicone rubber
1)Non- shrinkage (less than 0.1% )
2)high tensile and tear strength with high copy times
3) exceptional fluidity and good operability (mixing ratio at 1:1 )
4)high temperature resistant in 250 Centigrade
Operation instruction of platinum cured silicone rubber
Step One:Take 100g of part A and 100g of part B and mix in 1:1 and mix the two part evenly.
Step Two:vacuum pumping
Without exception, this step takes less than 10 minutes.
Note: The time for vacuum-pumping should be less than 3-5 minutes ,otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated.
Step Three: Pouring the mixture into the frame with original mold slowly .
