Abstract:
In the coating method, a pipe for transporting oil and/or gas mined from underground is provided. An acid curable resin is passed through the pipe to adhere the acid curable resin to at least a part of an inner wall of the pipe. Then, an acid curing agent is passed through the pipe to allow the acid curing agent to make contact with the acid curable resin such that the acid curable resin is cured.
Abstract:
Provided are robust paint coating systems on metal-coated plastic substrates and processes for forming such material systems as decorative components. An organometallic adhesion promoter is applied to a metal-coated plastic substrate. The metal coating comprises chromium (Cr), nickel (Ni) or combinations thereof. The organometallic adhesion promoter comprises (i) a transition metal selected from the group consisting of: zirconium (Zr), titanium (Ti), chromium (Cr), and combinations thereof, (ii) a first ligand complexed to the transition metal comprising an organofunctional group, and (iii) a second ligand complexed to the transition metal having a hydrolysable functional group. Then, one or more organic paint precursor materials are applied thereon. The hydrolysable functional group is capable of reacting with the metal-coated substrate and the organofunctional group with at least a portion of the organic paint precursor material to form a robust polymeric paint coating having a robust bond with the metal-coated plastic substrate below.
Abstract:
Provided is a method for producing a cylindrical nanoimprinting mold such that the outer peripheral surface of a cylindrical aluminum substrate is uniformly polished, and it is possible to effectively take advantage of the outer peripheral surface. The method forms an oxide film at the outer peripheral surface (14) of an aluminum substrate (10) after polishing the entire outer peripheral surface (14) of the cylindrical aluminum substrate (10) by means of a polishing body (26), wherein the polishing body (26) is moved in the axial direction to polish in a manner such that at least a portion of the polishing body (26) is protruding beyond the first end (10a) side and second end (10b) side of the aluminum substrate (10), and the portion of the polishing body (26) protruding beyond the aluminum substrate (10) is disposed on and supported by a cylindrical first support member (18); and second support member (20).
Abstract:
This invention relates to a method for phosphating metal surfaces in which the metal surfaces are treated with an aqueous phosphate and titanium-based colloidal activating agent prior to phoshating, wherein the activating agent comprises at least one water-soluble silicon compound having at least one organic group. The invention also relates to a corresponding activating agent.
Abstract:
A system and a method for pretreating an aluminum assembly includes selecting a blank having a thin film pretreatment layer and a lubricant coating applied to a surface. The blank is formed to a desired shape and an adhesive is applied to a selected portion of the surface. A cleaner is applied to the assembly to remove the thin film pretreatment layer and the lubricant coating from the surface except at the selected portion and a zirconium oxide conversion coating is applied to the assembly before painting.
Abstract:
A more efficient process of sealing an anodized aluminum article, which can facilitate higher production rates than conventional sealing techniques, includes steps of providing an article comprised of aluminum or an aluminum alloy that has been anodized, treating the oxide layer with a solution containing an anion capable of combining with a cation to form a water-insoluble precipitate, and contacting the treated oxide layer with a second solution containing a cation which combines with the anion to form a water-insoluble precipitate. In certain embodiments, the oxide layer can be treated with a dye to provide a sealed anodized aluminum article exhibiting enhanced dye retention.
Abstract:
The present invention develops a method of treating metallic or plastic substrates to form minor finish. After several pre-treatment steps to modify the surface situation of the substrate, whether for metallic or plastic material, to enhance the adhesion of above coating layers, a layer of minor finish will be applied, with the function of decoration shown with metal appearance and glossy. A changeable topcoat will be coated to protect below minor finish layer and achieve colorful decoration. All materials and processing steps are environmentally friendly, and involved without expensive facilities.
