Master Bond Master Sil 700 is a ready-to-use, one component high performance silicone elastomer compond for bonding, sealing, protective coatings and formed-in-place gaskets. This compound 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. Master Sil 700 is an excellent electrical insulator and provides vibration and shock protection for delicate electronic components. It remains flexible and provides excellent service over the board temperature range of -75°F (-60°C) to +400°F (205°C). Color is black. Master Sil 700 silicone adhesive/sealant is widely employed for its reliable and high quality performance for bonding, sealing and joining metal, plastics, electrical insulations, protective coatings, formed-in-place gaskets and encapsulation of sensitive electronic components. Typical properties of the cured compound include the following.
