Description: Master Bond MasterSil 151AO is a two component, low viscosity silicone compound for high performance potting and encapsulation. MasterSil 151AO combines high temperature resistance, good flexibility and thermal conductivity. MasterSil 151AO is an addition cured system and does not require exposure to air for complete cross-linking. It has a convenient 100 to five mix ratio by weight and will not outgas while curing. It is 100% solids and contains no solvents. MasterSil 151AO has an low viscosity enabling it to be highly desirable for potting and encapsulation. First and foremost, MasterSil 151AO, as is true with silicones in general, offers flexibility and high temperature resistance. It has good electrical insulation properties. Its flexibility allows it to withstand severe thermal cycling and resist vibration and shock. Also, it is very water resistant. These properties make this system well suited for applications involving sensitive optical and electrical components where heat dissipation is critical. Some additional applications include encapsulating heat generating electronic components, heat sink attachment and potting sensors, among many other uses. MasterSil 151AO is white in color. The service temperature range for this system is -65°F to +400°F. Key Features - Good thermal conductivity
