Operation instructions
Mix part A and pars B evenly with 100:3 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 there
will be no bubbles in the finished mold.
2) This step is less than 10 minutes. Otherwise, it Will cause cross-linking reaction, and no more further steps will be available.
3.Pouring casting or Brush molding
Notes:1) For simple pattern products we suggest use pouring operation way, which will be very easy to operate and demould. Pourable silicone require low viscosity which will be easy to flow smoothly and easy to de-air.
2)For delicate pattern products we suggest use brushing operation way, which can copy the pattern exactly. Brushable silicone require high viscosity which won't be easy to flow away and easy to brush.
3)We suggest to set the mold for another 12 hours after demould before put it into large production.
Package details:1kg/5kg/20kg/25kg/200kg
Features:
1.Almost no shrinkage
2.Good fluidity, operability and excellent operation
3.Good resistance to weather, temperature, aging, acid
4.Excellent tear strenght, comfortable duplcation times
5.High chemical resistance to aggressive components of some types of resins
6.Food grade silicone(environmental, odorless and nontoxic
7.High resistance to high temperature and aging(resist -60 to 250ºC)
Operate Process:
1. The surface of the original is clean and free.
2. Weight 100 Part A base and 3 part B in a clean container.
3. Stirring Part A base silicone before using thoroughly , as filler separation may occur upon prolonged storage.
4. Mixing Part A and Part B evenly until completely dispersed in the base.
5. Pouring the mixed base silicone and platinum curing agent as soon as possible onto the original
6. De-mold after 24 hours ,it is will improve the replicate times of silicone mold.
Note:It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 min under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.
