electronic potting silicon for circuit board module
Electronic potting silicone is a kind of two components(1:1 mixing 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 temperaturer .
Application of electronic potting silicone :
1.Applying for the surface of PC,PP,ABS,PVC,Metal ,etc.
2.High powered electronic encapsulation and DC/DC module and circuit board which requires heat dissipation and high
temperature resistance
3.Insulation ,waterproof and bonding of general electronic components
4.Filling for LED, LCD electronic display ,circuit board ,PCB substrate ,etc
5.Outdoor protection for LED screen.
(Pls note: the above data for this product in 25 °C temperature, 55 percent humidity conditions, for reference. The accurate data is measured by customers to when using.)
