  • Patent number: 11173672
    Abstract: Adhesive bonds are applied by mixing two adhesives with different properties and dispensing them to form bondlines between substrate pairs. The adhesives are then thermally cured and cooled. Varying the mix ratio permits one to vary the properties of the adhesive mixture so formed for use in bonding many different substrate pairs. The process allows potentially infinite variations of adhesive properties between those of the respective starting adhesives, simply by varying the mix ratio. The invention is especially adapted for use in manufacturing settings in which adhesives are to be applied in multiple places, but differing adhesive properties are needed among the various bonding areas.

  • Patent number: 9475904
    Abstract: Heat-curable epoxy resin compositions and the use thereof, for example, in motor vehicle construction and sandwich panel construction, are disclosed. Exemplary heat-curable epoxy resin compositions include, in addition to epoxy resin components A1, optionally A2, a hardener component B, a carboxylic acid C and a hydroxyalkylamide or hydroxyalkylurea H, an accelerator E for activation of the conversion of components A1, A2 and B. The compositions and the structural foams produced therefrom are notable for high mechanical strength, high glass strength and good adhesion capacity on metallic and nonmetallic substrates, and it is possible at the same time to dispense with the use of toxic or inflammable blowing agents.

  • Patent number: 9293328
    Abstract: Methods for adhering materials and methods for enhancing adhesion between materials are disclosed. In some embodiments, a polymer brush material is bonded to a base material, and a developable polymer resist material is applied over the grafted polymer brush material. The resist material is at least partially miscible in the grafted polymer brush material. As such, the resist material at least partially dissolves within the grafted polymer brush material to form an intertwined material of grafted polymer brush macromolecules and resist polymer macromolecules. Adhesion between the developable polymer resist and the base material may be thereby enhanced. Also disclosed are related semiconductor device structures.

  • Patent number: 9242505
    Abstract: A production method of workpiece is provided. First, an adhesive layer is applied on a workpiece, wherein a material of the adhesive layer includes thermosetting resin and radiationcurable resin. The adhesive layer is impressed by a mold, so that the adhesive layer forms a three-dimensional pattern. A first curing process is performed on the adhesive layer by one of radiation-curing and thermal-curing. The workpiece is punched after the first curing process is performed on the adhesive layer, so that the workpiece forms a three-dimensional workpiece. A second curing process is performed on the adhesive layer by another one of radiation-curing and thermal-curing after the workpiece is punched. In addition, a workpiece with three-dimensional pattern is also provided.

  • Patent number: 9138776
    Abstract: The invention relates to a procedure for applying a coating with metallic or ceramic finish on the entirety or part of the surface of a thermoplastic, metallic or metallic alloy article, which comprises: preparing the thermoplastic, metallic, or metallic alloy article; applying on the article a base polymeric layer based on aqueous dispersions of resins without volatile organic components or on dispersions in organic solvents of resins without urethane; curing the base polymeric layer; and depositing a single layer of a metallic or ceramic material on the article coated with the cured base polymeric layer. The curing of the base polymeric layer is carried out at a temperature of between 30 and 80° C. in the case of thermal polymeric layers, or by means of ultraviolet radiation in the case of photosensitive polymeric layers. Optionally, a second transparent polymeric layer can be applied for protective purposes.
