RTV Silicone Elastomer for High Performance Bonding and Sealing


Master Bond Inc., Hackensack, N.J. has developed Master Sil 700, a ready-to-use high performance silicone elastomer compound. This reliable and high quality silicone adhesive/sealant features a unique combination of flexibility and high temperature resistance. As such it is recommended for high performance sealing and joining of metals, plastics, electrical insulations, protective coatings and formed-in-place gaskets. With its excellent insulative properties, it has a dielectric strength of 530 volts/mil, and its remarkable 400% elongation it is also ideal for the encapsulation of sensitive electronic components as it provides ample vibration and shock protection.  
Master Sil 700 has a paste consistency and will not sag, slump or run off surfaces. It cures at ambient temperatures to a flexible rubbery solid when exposed to atmospheric moisture and remains flexible providing excellent service over the broad temperature range of -75°F (-60°C) to 400°F (205°C).  In addition to its superb electrical insulation properties, Master Sil 700 has excellent resistance to water and good sealing/adhesive properties, particularly to glass, plastics, metals and rubber, even including difficult to adhere silicone rubber itself. Master Sil 700s inherent flexibility allows for “repairability” when this property is needed. It is conveniently packaged in tubes, cartridges and 5 gallon (40#) pails.
