Operation instructions
1.Mix part A and pars B evenly with 1:1 mixing ratio.
Notes: 1) Weigh the two parts exactly by electronic weight. For example, the operation time will be shorten after adding too much catalyst.
2)Mix part A and part B evenly. Otherwise the silicon rubber will be partly solidified which will make the finished molds meet a short life and waste silicon rubber.
2.Vacuum pumping
Notes: 1) This step is not have to have, but it is best if there is one. It will discharge all air in the mixture successfully, so as to ensure that therewill be no bubbles in the finished mold.
2) This step is less than 10 minutes. Otherwise, itWill cause cross-linking reaction, and no morefurther steps will be available.
- Pouring casting
Notes: We suggest to set the mold for another 12 hours after demould before put it into large production.
