Claims
- 1. A method for protecting threaded connections with an anti-seize/lubricating system, the method comprising the steps of:a) coating the threads, prior to their make-up, with a solvent thinned resin based bonding composition comprising a suspending agent, a bonding agent, a thinning agent, and a metallic flake; b) drying the coated threads for a time sufficient to bond the bonding composition to the threads to form an anti-seize film on the thread; and c) coating the threads having the anti-seize film bonded thereto, prior to their make-up, with a fluid lubricating composition, where the anti-seize film and the lubricating composition form the anti-seize/lubricating system.

- 11. The method of claim 1, further comprising the step of:depositing onto the thread, prior to the first coating step, a metallic bonding film.
- 12. The method of claim 11, wherein the bonding film is selected from the group consisting of nickel, zinc, tin, a zinc-copper alloy, cobalt, and mixtures thereof.
- 13. A method for protecting threaded connections with an anti-seize/lubricating system, the method comprising the steps of:a) depositing onto the threads a metallic bonding film; b) coating the threads having the metallic bonding film deposited thereon with a solvent thinned resin based bonding composition comprising a suspending agent, a bonding agent, a thinning agent, and a metallic flake; c) drying the coated threads for a time sufficient to bond the bonding composition to the metallic bonding film on the threads to form anti-seize film coated threads; and d) coating the anti-seize film coated threads with a fluid lubricating composition, where the anti-seize film and the lubricating composition form the anti-seize/lubricating system.
- 14. The method of claim 13, wherein solvent thinned resin based bonding composition comprises:from about 0.1-5.0% by weight of the suspending agent; from about 2.0-10.0% by weight of the bonding agent; from about 65-90% by weight of the thinning agent; and from about 5.0-17% by weight of the metallic flake.
