Electronic Potting Silicone Rubber

详情

1.the feature of HY ***5
    HY ***5 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 ***5 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.*8 MPa for **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 *0???**0℃, the silicone will cure in *5 minutes; while in *5℃ room temperature, the silicone will cure around 8 hours.

 
4.Notes of Electronic Potting Silicone Rubber

a.The following material may hinder the curing of HY ***5, So pls use after the test. When necessary, pls clean the application areas.

Organotin compound or Condensation silicone with organotin

Sulphur, sulfide and sulfur rubber materials.

Amine compounds as well as contains the amine materials.

Pewters solder flux

b. HY ***5 should be sealed storage.The mixture should be used up disposably to avoid causing waste.

c. HY ***5 belongs to non-dangerous goods, but keep away from mouth and eyes.

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