Master Bond MasterSil 705C is an easy-to-use, one component, electrically conductive, carbon filled silicone for bonding and sealing. The material is a black colored paste. It cures readily at ambient temperatures when exposed to atmospheric moisture and is a non-corrosive type silicone. MasterSil 705C features moderately low resistance and is ideal for many bonding and shielding type applications. It is serviceable over the wide temperature range of -75°F to +400°F. MasterSil 705C is a cost effective alternative to the more expensive MasterSil 705S (silver filled) particularly in applications where only moderately low resistance is needed.
