A method for forming a multilayer coating film includes applying an aqueous first base coating composition (A) onto a cured electrodeposition coating film, applying an aqueous second base coating composition (B) without preheating, performing preheating, further applying a clear coating composition (C), and simultaneously heat-curing the first base coating film, the second base coating film, and the clear coating film. The aqueous first base coating composition contains a specific aqueous polyester resin, a specific aqueous acrylic resin, a specific aqueous urethane resin and a melamine resin. A breaking energy of a coating film formed of the aqueous first base coating composition and a peel strength between the coating film and the cured electrodeposition coating film are controlled to specific values.

A method for producing a green body includes forming a layer which contains a powder of a ceramic on a substrate, applying at least one solidifying composition on at least a part of the layer, repeating forming the layer and applying at least one solidifying composition at least one time, removing the solvent or dispersing agent at least in part for forming a green body, and removing the powder which has not bonded and thereby exposing the green body. The solidifying composition contains a dissolved or liquid organometallic compound, which has at least one atom other than C, Si, H, O, or N bonded to at least one organic moiety, an organic binding agent, and a solvent or dispersing agent.

Various embodiments directed towards methods of applying sizing to fibers are disclosed herein. In some embodiments, solvent can be used to dissolve a sizing material into a solution, which can then be used to coat the fibers. In some embodiments, a water bath is used to coagulate a sizing on the fiber surface and to remove the remove solvent after coating the fibers, so that water vapor can be created during a subsequent drying step as opposed to solvent vapors. In some embodiments, strong acids or strong bases can be used as the solvent.

A wet coating composition useful for coating a cellulosic fiber-based substrate is provided. The composition includes two aqueous emulsions. The first emulsion includes an oxidized paraffin/polyethylene wax and the second emulsion includes an ethylene/acrylic acid copolymer wax, ethylene/acrylic amide copolymer wax, ethylene/acrylic acid/acrylic amide copolymer wax or a mixture thereof. The oxidized paraffin/polyethylene wax has a surface energy less than or equal to 2 m N/m being substantially dispersive energy. The wet coating composition when dried forms a coating having a surface energy ranging from 20 to 60 m N/m being the sum of dispersive and polar energies. A process for treating a cellulosic fiber-based substrate with the wet coating composition, a substrate coated and articles including the coated substrate are also described. The process involves a heating step to allow migration of the coating towards a core of the cellulosic fiber-based substrate.
摘要:
A modifying agent of an alkaline electrolyzed water. A substance being supplied to a concrete structure in order to produce calcium silicate for repairing concrete and including an alkali metal silicate is defined as a concrete protective agent. The modifying agent is supplied to the concrete structure in advance of the supply of the concrete protective agent. The alkali metal silicate and the calcium ion included in the concrete protective agent contribute to the production of the calcium silicate. A method for repairing a concrete structure includes supplying the concrete protective agent to the concrete structure and supplying a modifying agent for a concrete structure including an alkaline electrolyzed water to the concrete structure, the step of supplying a modifying agent being performed before the step of supplying the concrete protective agent to promote production of the calcium silicate in the step of supplying the concrete protective agent.
摘要:
Provided is a method for readily forming a coating film on a surface of a substrate, that has an excellent applicability and is uniform or homogenous and has a good appearance. The present invention is a method for forming a coating film on a surface of a substrate. The method comprises the steps of: applying an aqueous coating composition to a surface of the substrate to form a liquid film, and drying the liquid film to form a dry film. The liquid film has a fine concave-convex shape including a plurality of convex parts and a plurality of concave parts. In the step of forming the dry film, the liquid film is dried to form the dry film in which the fine concave-convex shape of the liquid film is conserved.
摘要:
A method for coating metallic surfaces of substrates with surfaces of aqueous coating) compositions in the form of a dispersion and/or a suspension containing at least one stabilized binder and a gelling agent, the cations having been dissolved out of the metallic surface of the substrate in a pretreatment stage and/or during the contacting. The invention further relates to such a coating based on an ionogenic gel, in which the coating is formed by a process further described herein.
