Two-component silicone is distinguished and named for the single component silica gel. This product consists of two components and cures after mixing the two components in the right proportion. Generally divided into Condensation type and Addition type, the biggest dierence between the two is Condensation type will release low-molecular substance and Addition type will not, So Condensation type potting will shrink during curing and Addition type potting will not.
It can use in the high power electronic components, modular power supplies and circuit boards for potting protection,which has good heat conduction and temperature resistance. Such as LED driver power ,automotive HID lamp module power supply, automotive ignition system module power supply, network transformers, etc.
Two – Component condensation type potting :
