Contact Grease is a grease that protects slide contacts from sulfurization and oxidation.
It is resistant to thermal decomposition, has excellent resistance to acidic gases and chemicals, and is long-lasting. It is made of chemically stable synthetic oil. It has excellent cold resistance and can maintain fluidity even in environments below -40°C.
It reduces contact wear and contributes to durability. It has no effect on electrical characteristics when used in electronic components.
Contact Grease is used to protect electrical contacts in sliding parts of automobiles and electrical equipment from sulfurization and oxidation.
It is used in areas where power is switched. It increases durability by reducing contact wear and inhibiting sparking during connection. Also, since the contacts are no longer exposed to air, no oxide film is formed, reducing the possibility of contact failure. Even if the switch is a type that switches by sliding, the contacts do not conduct each other, eliminating the possibility of short circuit.
The strong film produced by the excellent contact protection effect inhibits contact wear and protects contacts from corrosive gases and oxidation.
Because it is made of chemically stable, inert synthetic oil, it has better oxidation stability than those made of mineral or synthetic oil. In addition, since it is a semi-fluid grease, it maintains its anti-corrosion and lubricating effects for a long time compared to oil-type products.
Because it is made of silicone oil, its viscosity is less affected by temperature changes than those made of mineral oil or synthetic oil.
The silicone fluid used has a flow point of -40°C or lower, so it has excellent low-temperature flowability to maintain lubricity.
The silicone fluid used is chemically stable and inert, so it has little effect on materials, especially on resins.
