Abstract:
This invention provides a coating for zinc coated steel surfaces and other zinc containing alloys, including zinc/iron, zinc/nickel, zinc/cobalt, zinc/aluminum, and any other suitable metal surface. The coating product of this inventions contains the following ingredients: copolymers made from acrylic, vinylacrylic, and acrylstyrene monomers, has carboxylic radicals from acrylic and/or methacrylic acids, and has an Ia of 30 to 60 mg. of KOH. The water soluble copolymers and lubricatory additives, which include natural or synthetic waxes, graphite, and molybdenum sulfide, are in solid form dispersed in aqueous solution at a ratio of from 1 to 10%.
Abstract:
Disclosed herein are a solid lubricating composition comprising a solid lubricant, a lubricating oil which is in a liquid or paste form at an ordinary temperature, a carrier for absorbing and possessing said lubricating oil, and a thermosetting synthetic resin binder, and a sliding member comprising a metal substrate and a solid lubricant composed of the lubricating composition.
Abstract:
A coating and bonding composition is disclosed. The composition includes suspending, bonding and thinning agents, and a metallic flake. The composition may be used with an environmentally friendly lubricating composition to form an environmentally friendly lubricating system for protecting threaded connections from galling or other damage. That system may be used in a method for protecting threaded connections that includes the steps of: coating me threads, prior to make-up, with the coating and bonding composition and then coating them with the environmentally friendly lubricating composition, after the coated threads have dried.
