Detailed Product Description
 
The liquid silicone rubber has no heavy metal and arene solvent, and can't bring volatility material when it is solidified,
 
The silicone rubber used for the seal of solar energy light-absorbing board  
1.Basic model: SG2513A/B
2.  Product Description
   The product is high transparent 2-part liquid silicone rubber,
    catalyzed by platinum,consisting of basis compound, cross
    linking agent, catalyst and additives.
3. Key features
     The product has no heavy metal and arene solvent,and
     can't bring volatility material when it is solidified,so the
     material is eco-friendly and nontoxic,high light transmittance
     and excellent weather resistance.
4.  Applications
     These products are particularly suitable for sealing of solar
     energy light-absorbing board which have an extremely high
     requirement for the transparency after they are molded.
5. How to use:
 Mix A and B equably in a 1 to 1 weight ration, injection molding into shape. The curing condition is 5 minutes at 150centigrade. The curing time depends on the thickness of the finished products.
6. Packaging :SG2513A/B is available in 20kgs pails.
 
7. Storage: They should be stored at room temperature, protected from light and moisture.

9. Remarks
a) The products should be kept far away from organics containing Nitrogen, , Sulfur; ion complex compound such as Sn, Pb, Hg, Bi, As, as well as hydrocarbon and ethylene complex, so that the platinum catalyst
will not be contaminated to be unable to cure.
b) The mixture of A and B components should be used up within 12 hours. Theoretically, the viscosity of the products will go up until crosslink cured, which will make the products functionless. Special attention should be paid  to the products at high temperature.
