Solid and Dry Film Lubricants

Solid and dry film lubricants form a dry layer or coating that excludes moisture and reduces friction, binding, and wear. They often contain additives such as corrosion, oxidation, and rust inhibitors. Extra pressure (EP) additives include chemically active agents such as sulfur, phosphorous, or chlorinated compounds that form a film to prevent seizure, sticking or surface adhesion under high pressure conditions. Solid and dry film lubricants are also used to provide shock or vibration dampening functions. Fire resistant, biodegradable, and microbe inhibiting products are available. Release agents that prevent materials from sticking or adhering to an underlying surface require periodic replenishment. Important specifications to consider include density, specific gravity, thermal conductivity, and dielectric strength.
