摘要
Methods for forming magnetic coatings on a nonmagnetic substrate include the application of a liquid film layer onto the substrate, the film layer being a dispersion of magnetic particles in a liquid resin binder solution which contains trioxane. The trioxane may or may not be removed from the cured layer. Thus, the trioxane may be present as a reactive solvent for the resin binder, in which case, a polymerization initiator for the trioxane is also present in the liquid film layer. The trioxane may then be polymerized in situ on the substrate to yield poly(oxymethylene).
