  • Publication number: 20200270483
    Abstract: A pressure-bonding adhesive member having a superior positional-adjustment function relative to an adherend having a surface mainly constituted of low-polarity plastic typified by polypropylene, and capable of adhering to the adherend with a sufficiently high adhesive force after positional adjustment. The pressure-bonding adhesive member containing an adhesive layer and plural convex parts formed on one surface of the adhesive layer, wherein, when the convex parts are in contact with a polypropylene plate and the adhesive layer is not in contact with the polypropylene plate, the adhesive member shows a frictional force of not more than 0.6 N/cm2 on the polypropylene plate and a shear adhesive force of not less than 50 N/cm2 to the polypropylene plate.

  • Patent number: 10570320
    Abstract: Provided is an adhesive member to be adhesively fixed through pressure which has both position adjustability and adhesiveness and is capable of producing a sufficient adhesive strength in addition to the position adjustability. The adhesive member comprises a support, a pressure-sensitive adhesive layer provided on one surface of the support, and a plurality of protrusion elements arranged, in spaced-apart relation to each other, on a principal surface of the pressure-sensitive adhesive layer on a side opposite to the support. Each of the protrusion elements is composed of an aggregation of a plurality of cohesive particles, wherein the adhesive member has a frictional force of 0.4 N/cm2 or less, with respect to a stainless steel plate serving as an adherend, as measured when the protrusion elements are in contact with a surface of the adherend, and a shear adhesive strength of 45 N/cm2 or more.

  • Publication number: 20190241769
    Abstract: A separator containing a substrate and a release layer formed on at least one side of the substrate wherein the separator shows a strain of not more than 7% when a load of 5N/20 mm is applied for one minute in the pulling direction, and when the substrate is cut in half in the thickness direction to divide the separator into two, an apparent elastic modulus in the pulling direction of one of the divided separators is larger than an apparent elastic modulus in the pulling direction of the other divided separator.

  • Publication number: 20190016925
    Abstract: A stickable-curable adhesive sheet bonds a deformation/conversion device to an adherend. The stickable-curable adhesive sheet contains a stickable-curable adhesive component and a curing component curing the stickable-curable adhesive component. The stickable-curable adhesive component has pressure-sensitive adhesiveness before curing and the initial tensile elastic modulus at 25° C. of the stickable-curable adhesive sheet after curing is 5×108 Pa or more.
