A method is provided to form a dust mitigation coating that also mitigates or repels water, ice, and other liquids. Techniques to coat the surfaces of equipment and items with these dust, liquid, and ice mitigation coatings, minimize or eliminate mission problems caused by dust, liquid, or ice accumulation, particularly in outer space or on another planetary body or moon. Further, the dust mitigation coatings exhibit a Lotus-like effect, making the coated surfaces ultra-hydrophobic. The present invention is also directed to techniques for improving the functioning of terrestrial-based equipment and systems where dust, liquid, or ice accumulation is a problem, such as in hospitals and other health contexts, to prevent contamination.

Threaded parts such as bolts are rust-proofed by using a treatment liquid including a binder resin containing silica and at least one of a modified epoxy resin obtained by graft polymerization using a carboxylic acid-containing acrylic polymer as a side chain and a modified acrylic resin obtained by graft polymerization using a carboxylic acid-containing acrylic polymer as a side chain. By using this treatment liquid, coating treatment can be carried out at one time without need to use an organic solvent. There is an advantage that the friction coefficient does not increase even when tightening is repeated.
