  • Patent number: 9932677
    Abstract: The present invention relates to a method for serial surface treatment of metallic components comprising aluminum surfaces, wherein an alkaline pretreatment is followed by a conversion treatment. According to the invention, the intention during the alkaline pretreatment is that a maximum value for the concentration of dissolved zinc is not exceeded, in order to ensure a sufficient quality of the corrosion-protective coating on the aluminum surface of the components following the surface treatment. In a preferred embodiment, the content of dissolved zinc is effectively held below the respective bath-typical maximum value of dissolved zinc by the addition of compounds constituting a source of sulfide ions. The functionality of the surface treatment can be additionally increased by likewise controlling the content of dissolved aluminum in the alkaline pretreatment such that, by adding compounds constituting a source for silicate anions, a threshold value for dissolved aluminum is not exceeded.

  • 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.

  • Patent number: 8859049
    Abstract: A plating method for an RF device is disclosed. The method includes (a) pre-treating the RF device made from a substrate material; (b) forming a copper plating layer by applying copper plating to the RF device; and (c) forming a thin-film layer over the copper plating layer, the thin-film layer made of a precious metal, where a thickness of the precious-metal thin-film layer is thinner than a skin depth at a working frequency band. The disclosed method makes it possible to provide a plating treatment with a low cost while providing a superior appearance quality.

  • Patent number: 8840963
    Abstract: The present invention relates to an aqueous epoxy resin composition which is able to contain a large amount of water because it uses an epoxy resin and a coagulant and thereby allows an emulsifier and water to be stably adsorbed and captured on tangled particle surfaces of the coagulant. The aqueous epoxy resin composition according to the present invention comprises a highly compatible formulation producing a good cross-linking bond in a curing reaction with a curing agent and hence it can effect functions including those of a coating agent, a primer agent, a mortar agent and an adhesive agent in a two-part formulation, and it entails a formulation using absolutely no volatile organic compounds in large amounts and hence it is environmentally-friendly and can also markedly reduce production costs.
