Product Feature of Electronic Potting Silicone Rubber
HY-9055 silicone rubber is a kind of low viscosity, Inherent flame resistance, two components addtion cured potting silicone with heat-conducting. It cures with both on room temperature and heated temperature. It has the feature of the higher temperature the faster of the curing time. It can be applied to electronic components for insulation, waterproofing, fixed and flame retardant. It mainly applied in electronic components surface with materials of PC(Poly-carbonate)PP ABS PVC, etc. and metal materials.

2. Typical Application of Electronic Potting Silicone Rubber
HY-9055 electronic potting silicone rubber 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.


3. Technical Guidelines of of Electronic Potting Silicone Rubber
a, Pls put part A and part B in separate container and stir evenly before mixing the two part together.
b, Mixing Ratio: part A: part B = 1:1
c, Deaeration the mixture in vacuum pump under 0.08 MPa for 3-5 minutes.Then the mixture could be used for pouring.

Note: 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?, the silicone will cure in 15 minutes; while in 25? room temperature, the silicone will cure around 8 hours.

There are many kinds of Encapsulating silicone rubber. Different kinds of potting silicone have great differences in temperature resistance, waterproofing, insulation, optical properties, adhesion properties of different materials and softness and hardness.

Hong Ye Jie only produce and provide rtv2 silicone rubber for electronic potting, which is consist of two parts, part A and B. Which will vulcanize in room temperature or heated temperature.
