Features:

1.Almost nil 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 200ºC)
 

Use-Method:
1.A, B component should be fully mixed in the weight proportion of 1:1. Curing time is base on the mould temperature. If the temperature is high then the time will be short and if the molded product is thick and big, the time will be long. The mould can be taken apart after curing.

2.During the process, the manual apray gun, pneumatic gun, and directly manual operation can be adopted, and if the big amount is used, the couble omponent mixing machine can be used and the large area can be sprayed by the compress air.

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.

FAQ

RTV 2 Silicone Rubber for Vacuum Bagging Durable Sprayable Liquid Silicone:

1. What's silicone products you are making?
--liquid silicone, silicone rubber, silicone oil; Due to different silicone molds, our silicone has different viscosity, and cause different hardness, density to meet the requests from client.  

2. Do you offer free sample to client?
--Yes, we can provide the sample for test.  

3. How about the quality control in your factory?
--We have professional QC team to control the quality during production. Goods will be 100% inspected before shipment.  

4. How to remove the bubbles during my mould making?
--After mixing liquid silicone with curing agent, please put the material into vacuum machine to take off the bubbles.  

5. How to get good silicone mould to use longer time?
--The best way is:   #A, Please choose the right liquid silicone according to your products.   #B, Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use.   #C, Silicone mould can be used longer after the whole silicone mould fully cured, so it's better to wait 2 hours after mould finished.  

6. Why silicone rubber add curing agent after mixing a lot of bubbles?  
--This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
