Abstract:
1. A method of applying to a region of a machine component an in-solution oil repellent obtained by dissolving an oil-repellent resin in a solvent, the method utilizing an applicator device made up of an applicator tip internally having a microthin flowpath that allows the in-solution oil repellent to flow through it, the microthin flowpath dimensioned to impart viscous resistance to the in-solution oil repellent when the repellent flows through the flowpath interior, a contacting piece disposed in an end portion of the applicator tip, in a position enabling a contacting surface of the contacting piece to be pressed against the region of the machine component during the repellent-application operation, wherein one end of the applicator-tip flowpath opens on a portion of the contacting piece, and a reservoir storing the in-solution oil repellent is stored and connected to the other end of the flowpath; the in-solution oil-repellent application method comprising: with the contacting surface of the contacting piece pressed against the region of the machine component, causing relative movement of the contacting piece superficially on the machine component along the region; wherein the viscous resistance imparted to the low-viscosity in-solution oil repellent by the microthin flowpath delays, to an extent enabling the repellent-application operation, the outflow of the oil repellent from the opening in the applicator-tip flowpath.
