Silicone Lubricating Oil Thickened with Carbon Black

Manufactured by DOW CORNING, MOLYKOTE 41 grease is a black carbon loaded conductive grease ideal for knife contacts on electrical switchgear both indoor and outdoor.

Oxidation Resistance:

• MOLYKOTE 41 is recommended for use in units that must remain operable when subjected not only to low and high operating temperatures, but also to severe weathering and oxidation

Applications:

• Knife-type electric power disconnect switches
• Ball and socket connections of power insulators

Caution:

• Temporary discomfort may be produced from eye contact with MOLYKOYE 41 grease
• If contact occurs flush eyes with water
