ABSTRACT:
A light-duty, multi-purpose lubricant particularly formulated for use on the diverse bearing surfaces mechanisms which operate in a dirty or dusty environment, such as bicycle chains. The lubricant comprises an insoluble bond weakening agent, preferably metallic soaps such as Calcium Stearate, in suspension in a volatile solvent-based solution of wax and oil. After application and evaporation of the solvent the composite dry lubricant exhibits good penetration and load bearing properties without the dirt-retaining character of oils or greases. The undissolved particles of the bond weakening agent combine with dirt particles to break-down portions of the lubricant into a dry flaky particles which are sloughed off the mechanism. Soluble waxes having different solid phase crystalline structures may be blended with the paraffin to reduce the rate of sloughing. The amount of solvent may be adjusted or eliminated depending on the application. A surfactant can be added provide for coating wet mechanisms.
