CA 2185223

A light-duty, multi-purpose lubricant particularly formulated for use on the diverse bearing surfaces of a bicycle chain and other similar low-speed and low-temperature mechanisms operating in a dusty environment. The lubricant comprises an insoluble soap, preferably Calcium Stearate in suspension in a volatile solvent-based solution of paraffin wax and Petrolatum. 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 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.

L'invention concerne un lubrifiant polyvalent de type pour service léger formulé notamment pour être utilisé sur les diverses surfaces portantes d'une chaîne de bicyclette et autre mécanisme similaire à vitesse lente et à faible température, fonctionnant dans un environnement poussiéreux. Le lubrifiant comprend un savon insoluble, de préférence du stéarate de calcium en suspension dans une solution à base de solvent volatile de cire de parafine et de pétrolatum. Après l'application et l'évaporation du solvent, le lubrifiant sec composite présente de bonnes propriétés de pénétration et de charge sans le caractère de rétention de saletés des graisses. Les particules non dissoutes de savon se combinent avec des particules de saletés afin de décomposer des parties du lubrifiant en une poussière floconneuse sèche, laquelle se détache du mécanisme.
