two parts liquid silicone potting compound for led circuit boards
liquid silicone potting compound is a kind of two components(10:1 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 liquid silicone potting compound:
1.Applying for the surface of PC,PP,ABS,PVC,Metal ,etc.
2.High powered liquid silicone potting compound 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.
