Description tin based liquid silicone rubber for gypsum GRC frame triangle molds high tensile strength low shrinkage
RTV2 is two components liquid silicone rubber, tin curing,industrial cure silicone elastomer flowable, vulcanizes at room temperature.
Two parts silicone rubber can be used for a long time in the temperature range of - 65 ° C - 200 ° C and keep its soft and elastic properties.
Application and Advantages
Mold making silicone rubber for reproducing and replicating art crafts, furniture, prototyping, architectural elements, garden ornaments, shoe, tire, soap, candle, jewelry, vacuum bag and so on, since molding silicone is suitable for casting resin, PU, PVC, polyester, gypsum, plaster, concrete, cement, stone, GRC, wax, jewelry and so on.
Advantages:
Good flow performance
Easy to operate
Low viscosity
Easy demold
Low shrinkage(No deformation
No whitening
High temperature resistant(-65C-200C)
Flexible and low viscosity which will copy finest details and patterns from exquisite products.
Aging resistance, acid and alkali resistance nontoxic, odorless

Operation Instruction (How to make mold with silicone rubber?)
Make sure your original molds perfect. fix it on a board. And fix the original mold on a board , then used four piece of board to enclose the original molds .
Step 2: Take 100 G parts A and add 20G parts B and mix them evenly.
＊Notes: Mold making silicon rubber is a kind of flowing liquid ,it contains two parts. Part A is a kind of flowing white liquid and part B is the curing agent or catalyst .Pls follow the step strictly:
1.Weigh the two part exactly by electronic weight..
If not , for example add two much catalyst , the operation time will be too fast to operate ,which will cause inconvinience to operate .
2.Mix part A and part B evenly.
Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.
Step 3: Vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further
steps will be available.
Step 4: Pouring casting or Brush operation
＊Notes:1. For simple pattern products we suggest use pouring operation way , which will be very easy to operate and demould. Pourable silicone require light 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 silicone mold for another 12 hours after demould before put into large production .
Warm tips :
1. As addition cure silicone is a kind of platinum cure system ,which will be easy to cause uncure problem ,so Kindly follow the tips below :
＊Do not mix with liquid condensation silicone rubber or even the tool which used for condensation silicone
＊Do not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As,Hg, Ph,
＊Do not add any pigment or powder into the addition cure silicone rubber without any testing to prevent uncure problem
