AUGUST 30, 2007 -- Master Bond Inc. (search for Master Bond) today introduced MasterSil 151, a new two-component, low viscosity silicone compound for high-performance casting, potting, and encapsulation.

According to the company, the formulation is designed to cure at room temperature or more rapidly at elevated temperatures. MasterSil 151 has superior electrical insulation properties, high tensile strength, and superb optical clarity, say Master Bond representatives. It has a service operating temperature range of -65 ° F to +400 ° F.

MasterSil 151 is tough and flexible with an elongation at break of 160% and a Shore A hardness of 45, reports the company. It has superior resistance to vibration, impact, and shock. It also is resistant to thermal cycling. MasterSil 151 has a dielectric strength of 460 volts/mil and a volume resistivity of 1x1015 ohm cm.

Master Bond MasterSil 151 has a 10 to 1 mix ratio by weight. Its low viscosity assures complete fill-in around complicated contours in even very complicated configurations, claim company representatives. Shrinkage upon cure is very low. Shelf life in original containers is six months at 75 ° F. MasterSil 151 is available for use in half-pint, pint, quart, gallon, and five- gallon kit containers.
