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 soap, preferably Calcium Stearate in suspension in a volatile solvent-based solution of paraffin wax, petrolatum and a surfactant. After application and evaporation of the solvent the composite dry lubricant exhibits good penetration and load bearing properties without the dirt-retaining character of greases. The optional surfactant is surrounded and deactivated by the other components so that the dried lubricant is water repelling. The undissolved particles of soap combine with dirt particles to break-down portions of the lubricant into a dry flaky dust which is 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.
