摘要:
Provided are (i) a one-pack epoxy resin which exhibits excellent storage stability in terms of not only composition viscosity but also flowability and (ii) use thereof. The one-pack type epoxy resin composition, contains, as main components, (A) epoxy resin; (B) a modified aliphatic polyamine compound; and (C) inorganic filler treated with a long-chain hydrocarbon-group containing compound. Therefore, the present invention achieves (i) the one-pack type epoxy resin composition which exhibits the excellent storage stability in terms of not only the viscosity but also the flowability and (ii) use thereof.
摘要:
An epoxy resin composition is a one-part epoxy resin composition for hermetic sealing of an electronic component or an electrical component, containing: a liquid epoxy resin; dicyandiamide; and a filler, the filler having an average particle size between 0.1 μm and 1 μm, the filler containing particles not less than 5 μm in particle size in an amount of not more than 20 wt %, and the amount of the filler contained in the one-part epoxy resin composition being between 5 and 60 parts by weight relative to 100 parts by weight of the liquid epoxy resin. This achieves a one-part liquid epoxy resin composition in which a great variety of curing agents can be used and dissociation of an epoxy resin and a curing agent is suppressed even when used in a gap of approximately several tens of micrometers.

A method for assembling an apparatus including a display sheet having a non-transparent part in at least a part of the display sheet, has a bonding step of bonding the display sheet to a housing. The bonding step has a first step of attaching the display sheet to the housing via a UV curable adhesive, and a second step of causing an ultraviolet light emitting apparatus to irradiate, from an external surface side of the display sheet. The display sheet is attached to the housing with ultraviolet light after the first step so that the ultraviolet light passes through at least a part of the non-transparent part of the display sheet and cures the UV curable adhesive.
