Master Bond's Two Component, Low Viscosity, Addition Cured Silicone System for High Performance Potting & Encapsulation and Sealing, Featuring High Temperature Resistance, Excellent Flexibility and Optical Clarity.
Master Bond MasterSil 151 is a two component, low viscosity silicone compound for high performance potting and encapsulation. MasterSil 151 is an addition cured system and does not require exposure to air for complete cross-linking. It has a convenient ten to one mix ratio by weight and will not outgas while curing. MasterSil 151 is 100% solids and contains no solvents. MasterSil 151 has an exceptionally low viscosity making it highly desirable for potting and encapsulation. First and foremost, MasterSil 151, as is true with silicones in general, offers remarkable flexibility and high temperature resistance. It has superb electrical insulation properties.
The system has remarkable flexibility that 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. Some additional applications include encapsulating LEDs, optical fiber cladding and potting connectors, among many other uses. MasterSil 151 is transparent, although, it can be formulated in various colors. The service temperature range for this system is -65°F to +400°F.
