Introduction
Master Bond offers a number of specialty two part silicones for bonding, sealing, protective coatings, and formed-in-place gaskets. These two part systems cure by the polymerization reaction that occurs when a curing agent is added. Master Bond's line of silicones includes high performance elastomeric RTV silicone rubber adhesives with a unique combination of flexibility and high temperature resistance. Because of their resistance to shock and vibration, Master Bond's two part silicones serve as excellent conformal coatings for sensitive electronic circuitry.
The flexibility inherent in Master Bond's two part silicones allows for easy repair of the adhesive after it has cured. Such “repairability” is possible even without any additional solvent. Besides for the high flexibility, these compounds resist humidity and extreme temperatures, some remaining serviceable from temperatures as low as -65°F to as high as 500°F.

Advantages of Master Bond Two Part Silicone Systems
Mater Bond two part silicone systems offer high reliability in service. They cure at room temperature and are easy to mix. This provides a cost saving over oven cured polymer compounds. Master Bond's two component silicones often can be cured in deep cross section thicknesses and are popular in encapsulation and potting applications. Two part silicones feature long term durability and have successfully withstood accelerated aging tests over long time periods. They are not affected by exposure to ultraviolet light or ozone.
