Abstract: A gypsum board corner assembly is formed with an integrated reinforcement strip. The strip may be a folded sheet-metal strip or a thin rod. First, a gypsum board is formed with a groove that extends substantially through the entire gypsum core, but leaves the laminate paper of one side. Then a reinforcement insert is placed in the groove. Here, the insert is formed of or includes ferromagnetic material. The insert is subjected to a magnetic field to pull the insert into the groove, by action of the magnet. After an amount of adhesive is applied in the groove, the gypsum board is folded along the groove while the insert is being pulled into the groove by the magnet. The resulting gypsum board corner assembly has a very accurately placed insert that defines a straight corner edge thereof.

Abstract: The present invention related to a process to improve the adhesion between a thermosetting laminate and a thermoplastic shell in making reinforced plastic laminates for sanitary fixtures, such as shower receptors, spas, bathtubs, sinks, lavatories and the like, and composites laminates for transportation, marine, and construction applications. The adhesion improvement is through a designed post-curing process of the cured composites laminates. The thermosetting resin used in the construction of composites laminate can be unsaturated polyester resin of any kind, vinyl ester resin, or combination of both.

Abstract: Aldimines of Formula (I), which can be used as latent curing agents in curing compositions, for example, in moisture-curing polyurethane compositions that have isocyanate groups. The aldimines are compounds that can be liquid at room temperature, can have a hardly noticeable aldehyde odor before, during and after hydrolysis, and can have a long shelf life. An aldehyde in polyurethane compositions that is released during hydrolysis has only a slight softening effect and can exhibit very little tendency to migrate or exude.

The amount of the conductive particles contained in the anisotropic conductive adhesive is 5 to 35 mass %. This anisotropic conductive adhesive is supplied to a connection terminal of a wiring board, and a connection terminal of an electronic component is preliminarily connected to a connection terminal of a substrate while arranging the anisotropic conductive adhesive therebetween. Then, the electronic component is heated without applying a pressure or while applying a low pressure to the electronic component to connect the substrate with the electronic component.
