RTV silicone rubber for LED and solar (PV) panels used for

Electronic components surface 

For materials of  PC(Poly-carbonate)

PP,ABS,PVC

Metal materials.

 RTV-2 Silicone Potting Sealant for LED Display and LED or PCB Potting

Feature of RTV silicone rubber for LED and solar (PV) panels  

Good Viscosity 

Inherent flame resistance

two components addtion cured potting silicone with heat-conducting

cures with both on room temperature and heated temperature 

higher temperature the faster of the curing time 

applied to electronic components for insulation 

waterproofing, fixed and flame retardant.   

 

Typical Application of RTV silicone rubber for LED and solar (PV) panels

RTV silicone rubber for solar (PV) panels could be applied to

- high powered electronics,  

- DC/DC module and circuit board which requires heat dissipation and high temperature resistance.

-It can be broadly used for LED screen, Wind Power Generator, PCB substrate, etc.

TECHNICAL GUIDELINES of RTV silicone rubber for LED and solar (PV) panels

1, Pls put part A and part B in separate container and stir evenly before mixing the two part together.

2, Mixing Ratio: part A: part B = 10:1B 

3, De-air in vacuum pump under 0.08 MPa for 3-5 minutes.Then the mixture could be used for pouring.

4,Pls note that the thickness of the silicone affects the curing time. If the silicone used is a little thick,then the curing time will be a little longer.The temperature also affects the curing time.When in lower temperature, we suggest customers appropriately heat the mixture to accelerate vulcanization. With temperature of 80~100°C, the silicone will cure in 15 minutes; while in 25°C room temperature, the silicone will cure around 8 hours.

 Notes: 
1.Pls use after the test. When necessary, pls clean the application areas.

2. LH 5035 A should seal storage. The mixture should be used up disposably to avoid causing waste.

3.LH 5035 A belongs to non-dangerous goods,

 but keep away from mouth and eyes.

4. When it gets stratified after a period of storage, Please mix it evenly before using, which does not affect the performance.

 

SHELF LIFE AND TRANSPORTATION  for LED and solar (PV) panels silicone

1. Twelve(12) months when stored at 24C in tightly closed original packages.

2. This kind of product is non-dangerous product, which could be transported as general chemicals.

3. Please consult the supplier after Storage beyond the expired date
