A process for manufacturing a putter with a bi-material shaft is disclosed herein. The putter comprises a putter head, the bi-material shaft, a mass member and a grip. The bi-material shaft comprises a body with a tip end and a butt end. The body comprises a metal section extending from the tip end to a connection point, and a composite section extending from the butt end to the connection point. The mass member is positioned within an opening at the butt end of the shaft. Mass from the shaft is transferred to the club head and the mass member in the butt end of the shaft.

A combined receipt and label roll comprises a core, and a web having a longitudinally-extending axis and wound on the core along the axis. The web includes (i) a substrate having a front side and a back side opposite the front side, (ii) a thermally-sensitive coating disposed on the front side of the substrate, and (iii) a water-based microsphere adhesive disposed on the back side of the substrate along the web axis. The water-based microsphere adhesive comprises at least four separate adhesive patches. The at least four adhesive patches are both sized relative to each other and positioned relative to each other on the back side of the substrate such that additional tack desired can be obtained by increasing volume of the adhesive patches without having to increase coat weight of the adhesive patches.

In an embodiment, an adhesive sheet has an expandable adhesive layer 2 on one side or both sides of a base 1, wherein the expandable adhesive layer 2 contains an epoxy resin including a polyfunctional epoxy resin, a phenol resin as a curing agent, an imidazole-based compound as a curing catalyst, and a temperature-sensitive foaming agent. The adhesive sheet has properties in good balance, such as fast curability, heat resistance, and adhesiveness, and also excellent properties such as thermal conductivity attributed to a good filling property.

A (meth)acrylic adhesive film, an optical member including the same, and an optical display apparatus including the same are provided. The (meth)acrylic adhesive film includes organic particles, and further includes greater than 0 wt % to 5 wt % of inorganic particles. The (meth)acrylic adhesive film has a haze of 1% or less and an initial dent formation height of 4.5 cm or more.

An adhesive sheet is a thermally expandable and thermosetting adhesive sheet including a substrate and a first layer provided on at least one surface of the substrate. The first layer contains an adhesive portion having an adhesive composition and thermally expandable first particles contained within the adhesive composition, and second particles provided in the adhesive portion and having different materials from those of the first particles, and each of the second particles is larger than each of the first particles.

Disclosed are a method of preparing an elastic pressure-sensitive adhesive tape and an elastic pressure-sensitive adhesive tape. Main components of the adhesive include a polyacrylate resin with a carbon-carbon double bond and a diluent monomer with a carbon-carbon double bond. A quasi-microcapsule powder component is adopted, wherein the shell material of the quasi-microcapsule powder selects a cellulose-based water soluble polymer, and the core material selects low boiling point alkane, wherein the preparation method combines UV curing, heating, and shell burst, to obtain an elastic adhesive layer, whereby to prepare a pressure-sensitive adhesive tape product. Compared with conventional elastic pressure-sensitive adhesive tapes, the preparing method as disclosed has a simple manufacturing process. The pressure-sensitive adhesive tape obtained from the disclosed preparing method overcomes the restrictions of conventional foam strips and provide good cushioning and compression properties without using foam as the carrier.

An elastomeric mastic sealant composition and method of manufacturing are disclosed. In certain embodiments, the composition may include between about 13 and about 19 weight percent or between about 11 and about 15 volume percent of acrylate-acrylonitrile copolymer. The composition may further comprise one or more of between about 36 and about 41 weight percent or between about 29 and about 34 volume percent of styrenated acrylic polymer; between about 1 and about 2 weight percent or between about 0.9 and about 1.7 volume percent of surfactant; between about 0.6 and about 1.4 weight percent or between about 0.4 and about 1 volume percent of dispersant; and between about 0.4 and about 1 weight percent or between about 29 and about 40 volume percent of pre-expanded compressible microspheres having an organic outer surface and introduced by a closed mixing system into the copolymer. In some implementations, the disclosed composition and method forms a closed-cell, semi-foam, mastic sealant using gas-filled, flexible, organic microspheres to create a product that once cured, is elastic and compressible under pressure without unduly protruding in an outward direction when compressed, thereby allowing the applied sealant to compress in an enclosed, maximum-filled channel unlike typical mastic sealants (while retaining the ability to rebound). This allows the sealant in such implementations to function as a gasket, and to have properties including vibration damping, insulating, and/or condensation resistance.

The present disclosure relates to a process of manufacturing a moisture-curable adhesive composition, wherein the process comprises the steps of: a) providing a multi-screw extruder comprising a reaction chamber; b) providing reactants and reagents comprising: i. at least one isocyanate; ii. at least one amine; and iii. optionally, at least one plasticizer; c) incorporating the reactants and reagents into the reaction chamber of the multi-screw extruder, thereby forming a reaction product comprising a urea derivative; and d) incorporating at least one moisture-curable prepolymer into the reaction product resulting from step c), thereby forming a moisture-curable adhesive composition. In another aspect, the present disclosure is directed to a moisture-curable adhesive composition obtainable by the process as described above.

An adherable element is disclosed, comprising a decorative element having a support surface, and a pressure activated adhesive system pre-coated on the support surface of the decorative element for adhering the decorative element to a surface, the adhesive remaining uncured until activated by application of a threshold pressure. The adhesive comprises a matrix comprising a hardener and a plurality of microcapsules filled with an adhesive resin, the microcapsules being configured to rupture on application of the threshold pressure, thereby exposing the resin to the matrix and allowing the resin to react with the hardener to form an adhesive bond between the decorative element and the surface. The matrix may further comprise a rheology additive such that the matrix has a higher viscosity than the hardener at room temperature. Methods of making an adherable element, and decorative articles comprising the adherable element are also disclosed.

The present invention relates to a redetachable adhesive tape having a carrier based on a crosslinked polyurethane and an adhesive layer based on vinylaromatic block copolymer, to a method for producing the adhesive tape and the use of the adhesive tape in the production of electronic components.
