Usage of Waterproof Electronic Potting Liquid Silicone Rubber
 Insulation, waterproof and bonding of general electronic components.
 
Characteristics of Waterproof Electronic Potting Liquid Silicone Rubber
 Addition electronic potting compound is a kind of two components (1:1mixing ratio) addition cure silicone with the Characteristics

of heat-conducting, low viscosity, Inherent flame resistance, waterproofing, etc. It can cure both at room temperature and heated

temperature and the curing time can be accelerated by higher temperature.
 
Application of Waterproof Electronic Potting Liquid Silicone Rubber
       • Applying for the surface of PC (Poly-carbonate), PP, ABS, PVC, Metal, etc.
       • High powered electronic encapsulation and DC/DC module and circuit board which requires heat dissipation and high

temperature resistance.
       • Insulation, waterproof and bonding of general electronic components.
       • Filling for LED, LCD electronic display, circuit board, PCB substrate, etc.
       • Outdoor protection for LED screen.

Notes and operation instructions of Waterproof Electronic Potting Liquid Silicone Rubber
       1) The following material may hinder the curing of electronic potting compound silicone, so please use after the test.

When necessary, please 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
       2) Deaeration the mixture in vacuum pump under 0.08 MPa for 3-5 minutes.Then the mixture could be used for pouring.
       3) Please 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.
       4) Above electronic potting compound silicone should be sealed storage. The mixture should be used up to avoid causing

waste.
       5) Above silicone belongs to non-dangerous goods, but keep away from mouth and eyes.
       6) When it gets stratified after a period of storage, please mix it evenly before using, this does not affect the performance.
