A two component silicone rubber system has been certified for medical applications per the USP Class VI specification. The base resin, upon addition of the curing agent, cures at ambient or more quickly at elevated temperatures to a tough, flexible, optically clear silicone rubber. The low viscosity of this silicone elastomer compound assures complete fill-in around complicated contours in even very complex configurations. This characteristic together with its 160% elongation, low linear shrinkage of less than 0.1%, low outgassing, strong electrical insulation, and resistance to vibration and shock makes the adhesive suitable for demanding applications. Its service temperature range is -55°C to 205°C, and it is well suited to repeated sterilization.
