    摘要: The present invention provides a microcapsule-type curable resin composition to be applied to a screwing member, capable of reducing the generation of crumbs when the screwing member is screwed into a base material, having excellent anti-loosening effect. Further, the present invention provides a method for producing a screwing member, including applying the microcapsule-type curable resin composition to a surface of a screwing member, and drying the composition to form a precoated adhesive layer. Further, the present invention provides a screwing member having a precoated adhesive layer formed by applying the microcapsule-type curable resin composition to the surface of the screwing member and drying the composition.
    The present invention relates to a microcapsule-type curable resin composition containing the following components (A) to (D) :
    Component (A): an epoxy resin
    Component (B): a water-dispersible binder
    Component (C): a curing agent for an epoxy resin
    Component (D): a hollow filler.

    摘要: An object is to provide a conductive resin composition that demonstrates good conductivity and excellent adhesion (joining strength) with respect to various types of base materials and is useful as conductive inks, conductive adhesives, circuit connection materials, etc., and also to provide a conductive film formed by the conductive resin composition, a conductive ink containing the conductive resin composition, a conductive adhesive containing the conductive resin composition, and a circuit connection material containing the conductive resin composition. As a solution, a conductive resin composition is provided that contains (a) tin powder, (b) epoxy resin, and (c) organic acid compound, and satisfies requirement (A) and/or requirement (B) below:
    (A): the content of the (a) tin powder, relative to the total amount, 100% by mass, of the (a) tin powder, (b) epoxy resin, and (c) organic acid compound, is 90.1% by mass or higher; and/or
    (B): (d) curing agent is contained, and (d) curing agent includes one or more types selected from (d1) acid anhydride-based curing agents, (d2) thiol-based curing agents and (d3) phenol-based curing agents.

    摘要: Provided is a rubber composition that can improve the balance between the hysteresis loss of rubber at low strain and the hysteresis loss of rubber at high strain. The rubber composition comprises a rubber component, and at least one compound selected from the group consisting of the general formulas (1) and (2),

            HS-R-COOM     (1),

    and

            MOCO-R-(S) n -R-COOM     (2),

    where R is independently a linear or branched hydrocarbylene group having 8 or more carbon atoms in a linear portion connecting the sulfur atom and the COOM group; M is independently an atom selected from the group consisting of an alkali metal and an alkaline earth metal; and n is an integer from 2 to 8.

    摘要: A chloroprene rubber composition comprising 0.8 to 4 parts by weight of 2,4,6-trimercapto-s-triazine and 0.5 to 4.5 parts by weight of tetrabenzylthiuram disulfide based on 100 parts by weight of chloroprene rubber. The chloroprene rubber composition maintains processability (scorch time) and productivity (crosslinking rate) equivalent to those of conventionally used crosslinking systems, without using substances subject to environmental regulations in crosslinking systems, and at the same time, improves physical properties, such as strength, elongation, and compression set characteristics.
