Non-deleterious dry film lubricant coating composition, rubber sealing element coated therewith; and method of

摘要

A non-deleterious coating composition for the deposition of a dry film lubricant coating on a rubber sealing element comprises: (a) 1 to 10% by weight of a component selected from the group consisting of waxes and normally solid aliphatic alcohols; (b) 1 to 10% by weight of a lubricating oil; and (c) the balance being a solvent for (a) and (b); wherein the solvent, when applied to the rubber sealing element, in said coating composition, evaporates from the coating composition before any substantial degradation of the physical properties of the rubber sealing element occurs. A method for coating a rubber sealing element and the rubber sealing element coated with the dry film lubricant are also disclosed. The invention finds particular applicability in the lubrication of rubber sealing elements, e.g., O-rings, which will be utilized in the manufacture of devices by automated assembly techniques.
