  • Publication number: 20210259891
    Abstract: [Problem] To provide a body surface patch that has a simple configuration and high handling ability during being applied, and high flexibility and elasticity that enable fitness to the profile and expansion of a body face after being applied, and can reduce the adhesive flow. [Solution] A body surface patch is provided that includes: a substrate having a top face and a bottom face; an adhesive layer covering at least part of the bottom face of the substrate; and a releasable adhesive protecting film covering the adhesive layer. The substrate has a thickness of 20 to 90 ?m and the adhesive layer has a thickness of 40 to 160 ?m. The adhesive layer at least contains a radiation curable resin and a hydrophilic polymer compound.

  • Patent number: 10556038
    Abstract: Provided are a dermal adhesive composed of a radiation-curable resin and capable of reducing stuffiness that causes rash or itch, a patch including the dermal adhesive, and a method for producing the dermal adhesive. Also provided is a porous membranous dermal adhesive formed through irradiation of a radiation-curable resin with radiation rays. Further provided is a patch including a base sheet and the dermal adhesive disposed on the base sheet. Still further provided is a method for producing a porous membranous dermal adhesive, the method including applying a dermal adhesive composition containing a radiation-curable resin to an adherend so as to form a porous membranous dermal adhesive, and irradiating the dermal adhesive composition with radiation rays.

  • Publication number: 20160121018
    Abstract: An object of the invention is to provide an adhesive composition for skin that gives an adhesive for skin that can be coated readily and is highly cohesive and also an adhesive for skin and an adhesive sheet for skin prepared by using the adhesive composition for skin. Provided is an adhesive composition for skin including a radiation-curable resin and a reactive diluent that reacts with the radiation-curable resin. The adhesive composition for skin gives an adhesive for skin that can be coated readily and is highly cohesive. Also provided are an adhesive for skin prepared by irradiating the adhesive composition for skin with radiation and an adhesive sheet for skin including a base sheet and an adhesive layer of the composition for skin formed thereon.

  • Patent number: 6027777
    Abstract: A forming material for the fabrication of appliances for fixing, supporting, correcting and holding human bodies, characterized by a main forming material body including a quantity of granulated materials each coated with a moisture-curable urethane prepolymer contained within a water-permeable material container, the main forming material body being hermetically enclosed in a moisture-impermeable material container, wherein the moisture-curable urethane prepolymer and the water-permeable material container are unreactive with each other and have a low adhesive strength with respect to each other to provide good long term preservability and ease of operability to allow modeling and conforming the main forming material body to a desired shape.
