Technical guidelines of  RTV-2 liquid silicone rubber for Led Driver  :

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 = 1:1

3, Deaeration the mixture 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.
