QSIL550, 250G

QSil 550 2-part series are 100% silicone solids elastomer designed for electronic potting and encapsulation applications. This two component system offers a flame retardant, thermally conductive, low modulus material that is readily repairable. It is designed for potting electronics to provide environmental protection (e.g. sterilization units). Suitable for higher working temperatures.
