Electric contact failure-proof oil and method for preventing electric contact failure

摘要

An oil comprising an amino-modified silicone fluid containing an amino group with an amine equivalent of 10,000 to 200,000 g/mol and having a viscosity of 10 to 100,000 centistokes at 25° C. is effective in preventing any electric contact failure in relays, switches, motors, corotrons and similar electric elements.
