  • Patent number: 7863374
    Abstract: Self-curable water-based solid adhesives of this invention include the following components (A), (B), (C), and (D): (A) an anionic-group-containing polymer terminally having an alkoxysilyl group, the polymer being a reaction product of a compound (A1) containing no anionic group and having plural isocyanate-reactive groups, a compound (A2) having an anionic group and plural isocyanate-reactive groups, a polyisocyanate compound (A3), and an alkoxysilane compound (A4) containing an isocyanate-reactive group; (B) a basic compound; (C) water; and (D) a gelling agent. The self-curable water-based solid adhesives of the present invention can be applied with good workability, have good fitting after attachment, have good adhesion to plastics, metals and glass and exhibit excellent heat resistance and water resistance after curing. They are highly safe to humans and the environment. They also have excellent shape retention and slidability and can be easily applied.

  • Patent number: 5411345
    Abstract: Disclosed is a felt-tipped pen type adhesive applier comprising: a container for adhesive; valve mechanism provided on the container for controllably supplying the adhesive from the container; and a server for receiving the adhesive supplied through the valve mechanism in order to serve the adhesive. The server comprises: a holder covering the outside of the valve mechanism; a member permeable to the adhesive and extending from the inside of the holder to the outside thereof and being axially slidably and fittingly supported by the holder, the permeable member cooperating with the valve mechanism to operate the valve mechanism in response to axial movement of the permeable member; a support for slidably and fittingly supporting the permeable member inside of the holder to facilitate transportation of the adhesive from the valve mechanism to the permeable member; and mechanism for preventing the adhesive from leaking out of the server due to pressure change inside the server.
