ELECTRO-SEAL is a waterproof, flexible and permanent rubber coating that will act as a barrier against moisture-causing rust and corrosion, even when totally submerged. ELECTRO-SEAL can be applied on any surface to provide a rubberized body that conforms to any surface with an extremely tight bond. Dries crystal clear and will not discolor or harm any surface. ELECTRO-SEAL is ideal for use as an insulator for electricity. The volume resistance of this material makes it ideal for use on terminals to protect against corrosion and moisture. It can be used as an insulator in connection boxes and exterior wire connections.
