  • Patent number: 9034430
    Abstract: A method for preparing a metal substrate for inkjet CTP, comprising: treating a metal substrate by anodizing or non-anodizing (such as sandpaper burnishing, sand blasting, polishing, or brushing), and then applying a hydrophilic polymer paint on the surface of the metal substrate. Due to the existence of nano-size or micron-size oxide particles in the hydrophilic polymer paint, the metal substrate has high specific surface energy, while the metal substrate has a certain roughness, therefore the metal substrate has ink absorbency and good abrasive resistance. The metal substrate can reduce the spread of ink droplets and produces print image having better resolution and definition. The non-anodizing method can avoid environmental pollution which is caused by waste acid and waste alkali discharge of anodizing method.

A first later of resin may be applied to an epoxy layer that is applied to the pool surface to provide better adhesion while the epoxy is still tacky (hot-flocking). The hot-flocking causes the resin and the epoxy to blend into a single layer. An additional layer of resin may be applied after the epoxy and the first layer of resin fully cured. After the second layer of resin has cured an additional layer may be applied to provide designs and/or markings. The designs/markings may be produced with tape and/or stencils and the next layer may be applied to the non-covered areas to provide the desired look.

  • Patent number: 8597738
    Abstract: The synthesis of ordered arrays of GSC's by re-growth from pre-patterned seed crystals that offer an approach for scalable fabrication of single crystal graphene devices while avoiding domain boundaries is demonstrated herein. Each graphene island is a single crystal and every graphene island is of similar size. The size of graphene island arrays can be as small as less than 1 mm2 or as large as several m2. The distance between each GSC island is also adjustable from several micrometers to millimeters. All of the graphene islands are addressable for devices and electrical circuit fabrication.

  • Patent number: 8580346
    Abstract: Plastic restoration kits and methods for effectively restoring the light transmission and optical clarity properties to a plastic surface such as an aircraft window. The kits and methods restore plastic surfaces that have been damaged by scratching and/or UV-induced oxidation. The kits and methods employ a polishing composition and optionally a lusterizing composition, each having particles selected so as to polish and lusterize a plastic surface. After polishing and lusterizing, a UV protective composition that forms a hard UV protective coating is applied. The polishing and/or lusterizing compositions may include agglomerated abrasive particles dispersed in a liquid or gel carrier that progressively break down in size when exposed to oxygen and mechanical pressuring during polishing or lusterizing.

  • Patent number: 8524540
    Abstract: A process for increasing the adhesion of a polymeric material to a metal surface, the process comprising contacting the metal surface with an adhesion promoting composition comprising: 1) an oxidizer; 2) an inorganic acid; 3) a corrosion inhibitor; and 4) an organic phosphonate; and thereafter b) bonding the polymeric material to the metal surface. The organic phosphonate aids in stabilizing the oxidizer and organic components present in the bath and prevents decomposition of the components, thereby increasing the working life of the bath, especially when used with copper alloys having a high iron content.

  • Patent number: 8486870
    Abstract: Embodiments of the present invention may provide textured surfaces to be lubricated, the texturing to enhance the effectiveness of the intended nano-lubrication. The texturing may make asperities and depressions in the surface to be lubricated. This texturing may be executed, for example, by chemical etching, laser etching, or other techniques. This texturing may create locations in the lubricated surface to hold or anchor the intended nano-lubricants, to facilitate the creation of a tribo-film on the surface when the lubricated surface is used under pressure, and resulting in delivery of multiple chemistries from the nano-lubricant.

  • Patent number: 8399103
    Abstract: A method of a pre-treatment process for coating notably improves both the surface roughness of a coating layer of a cemented carbide cutting tool and the bonding force of the coating layer to the substrate. According to the method, a sintered surface layer within a range of 0.5-5 ?m, which corresponds to the tungsten carbide particle size of a substrate, is properly removed from the substrate surface of a cemented carbide cutting tool. Thus, a porous sintered surface layer having a non-uniform structure is removed and a substrate surface having high structure density and evenness is provided compared to blasting pre-treatment. In order to obtain a sufficient bonding force between a coating layer and the substrate, the surface ratio of open pores, which exist around tungsten carbide particles appearing by removal of the porous sintered surface, is equal to or more than 5%.
