Product Description
    Rongxingda Transparent Silicone Rubber is a two-component silicone rubber composed of A and B. The part A is transparentand the B as a hardener of part B. Before curing,part A is high viscosity liquid and part B is clear liquid. MixingpartAandBattheratioof10:1,thecross-linkingreactioncanbeachievedatroomtemperature,alsocuringtimecan be accelerated by heating. After curing, silicone elastomer materials with high transparency can be formed. When mixing part A and B , no heat will be released. It’s suitable for all kinds of products ofsilicone mold development and production according to the different hardness after curing. 
*FDA certification, food grade (environmental, tasteless,non-toxic) 

* Long-term and stable use at the range of -50℃~250℃ 

* High transparency after cured  

*Excellent tear and tensile strength 

* Low shrinkage 
Product Paramenters
1.The working time of RTV2 silicone rubber indicates how long the material will  remain fluid at 23°C~25°C.However, work should be carried out in the shortest time,because viscosity increases with time.

 2. The curing time of additional rtv2 silicone rubber is related to the temperature. 

3. The above is Rongxingda common data, we can adjust all the data according to customers requirements

Company Profile

    Rongxingda Silicone was established in 2005.It has two companies, Shenzhen Rongxingda Polymer Material Co., Ltd. and Dongguan Rongxin Silicone Technology Co., Ltd. The production base is located in Tianxin Industrial Zone, Dongguan, Guangdong and a land area of 5,000 m2. 

    The company has provided R T V 2 tin cured and platinum cured liquid silicone rubber to customers for years, especially for mold making silicone rubber, potting silicone, silicone foam, urethane rubber and polyurethane resin. We inspect the product quality if they reach the standard before the products export and we provide the professional instructions. Excellent quality and complete after-sales service has won the favor and approval of many domestic and foreign customers. 
1. What kind of liquid silicone products you are making?
 --Tin cured silicone rubber, Platinum cured silicone rubber, Transparent silicone rubber, Silicone foam, Urethane rubber, Polyurethane resin, Potting silicone rubber; We can adjust all the data according to the customers requirements 

2. Do you offer free sample to client?
 --Yes, we can provide the sample for test. Try our sample , I think you will satisfied with our products 

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 make the silicone mould to use longer time? 
--The best way is:
 1)Please choose the right liquid silicone according to your applications. 
2)Don’t use too much oil in mold making, because it can make the silicone mould become soft. 
3)Silicone mould can be used for a long time , it’s better to wait 2 hours after the mould completely cured 

5. Why bubbles occurred after mixing the part A and part B ? 
 --This is normal physical phenomenon. Because the silicone rubber is a liquid with viscous,it will produce some bubbles when mixing, so you'd better to use vacuum machine to remove the bubbles before pouring.
