MasterSil 415 One-Part Silicone Elastomer
Description
A one-component high-performance silicone elastomer compound for bonding, sealing, and coating called MasterSil 415. This formulation has high transparency and is particularly well suited for optical and display applications. It cures at ambient temperatures to a flexible rubbery solid when exposed to atmospheric moisture. It is easy to apply and has a paste consistency. It can be applied on vertical surfaces without sagging or running.
MasterSil 415 has a convenient set-up time of 8-12 minutes at 75°F. It is a superb electrical insulator and has a dielectric strength of 500 volts/mil (1/8" thick test specimen). It can be used over an extremely wide service temperature range of -185°F to +400°F. It is highly recommended when low-temperature serviceability is of major importance.
MasterSil 415 has excellent resistance to vibration, impact, and shock. It also offers superior moisture resistance and weather ability. It has a Shore A hardness of 30 and an elongation at 75°F of 400. Tensile strength is 325 psi. Master Bond MasterSil 415 has a 6 months shelf life at 75°F in original unopened containers. It is available for use in tubes, cartridges, and 5-gallon pails. It is FDA certifiable and meets the MIL-A-46106 specification.
