MasterSil 151 low-viscosity silicone compound

MasterSil 151 is a two-component, low-viscosity silicone compound suitable for high-performance casting, potting and encapsulation. This formulation can be cured at room temperature with little shrinkage. It has excellent electrical insulation properties and optical clarity. With high tensile strength, an elongation at break of 160%, and a Shore A hardness of 45, it is tough and flexible. It has a dielectric strength of 460 V/mil and an operating temperature range of –65°F to +400°F. MasterSil 151 has a 10-to-1 mix ratio by weight, and its low viscosity assures complete fill-in around complicated contours regardless of configuration. Shelf-life in the original containers is 6 mo when stored at 75°F. This compound is available in half-pint, pint, quart, gallon and 5-gal kits.
