METHOD FOR FORMING METAL PATTERN
The present invention relates to a method for forming a metal pattern on a pattern formation section set on a base material. In the present invention, a substrate provided with a fluorine-containing resin layer on a surface of the base material including the pattern formation section is used. The present inventive method for forming a metal pattern includes steps of: forming a functional group on the pattern formation section; and applying a metal ink including an amine compound and a fatty acid as protective agents to the base material surface to fix the metal particles on the pattern formation section. In the present invention, a fluorine-containing resin having a surface free energy measured by the Owens-Wendt method of 13 mN/m or more and 20 mN/m or less is applied as the fluorine-containing resin layer. Further, a metal ink including ethyl cellulose as an additive is applied as the metal ink.
COATING AGENT FOR OIL SEAL
A coating agent for oil seal comprising 10 to 90 parts by weight of a filler and 10 to 40 parts by weight of a wax, based on 100 parts by weight of isocyanate group-containing 1,2-polybutadiene, and being prepared as an organic solvent solution, wherein as the filler, silicone resin particles having a particle size of 0.5 to 10 μm and fluororesin particles having a particle size of 0.1 to 2 μm are each used at a ratio of 20 to 80 wt. % of the total filler amount. The coating agent for oil seal can exhibit excellent seal performance inherent in oil seal while maintaining excellent dispersibility of the coating agent, and can further achieve low torque characteristics.

Pre-treating polymer tubing or hose with a hydrophobic coating to reduce depletion of corrosion inhibitor
An inside surface of a hose for use with liquid-cooled cooling plate assemblies and other applications that contain copper (Cu) components is pre-treated with a hydrophobic coating to reduce depletion of a copper corrosion inhibitor (e.g., benzotriazole (BTA)) dissolved in a liquid coolant (e.g., deionized water) that flows through the hose. Exemplary hydrophobic coatings include, but are not limited to, polydialkylsiloxanes such as polydimethylsiloxanes. In one embodiment, a multilayer hose is immersed in a solution containing hydrophobizing siloxane monomers dissolved in a solvent. The coated multilayer hose is then dried to evaporate the solvent. As the solvent evaporates, the siloxane monomers bind together to form the hydrophobic coating. In some embodiments, one or more hoses each provided with a hydrophobic coating interconnect liquid-coolant cooling system components (e.g., cold plates, headers, manifolds, pumps, reservoirs, and heat exchangers) of a cooling apparatus that removes heat from one or more electronic components.
