Abstract: A pressure sensitive adhesive tape for bonding a golf grip to a shaft of a golf club. The tape construction includes a carrier or substrate having a pressure sensitive adhesive on one side and an activatable adhesive on the other side. A release liner may be applied to protect the adhesive layers. The pressure sensitive adhesive is utilized to adhere the tape to the shaft of the club leaving the activatable adhesive on the outside of the tape. In a preferred embodiment, the adhesive is activated using a soap-water mixture which causes the adhesive first to become slippery allowing application of the grip and then setting-up to bond the grip to the club. Alternatively, the adhesive may be activated using a solvent.

Abstract: A reinforcement panel with a cellulose surface material improves adhesion of the panel to one or more wood segments in wood structural members such as laminated beams, wood I-beams, and trusses to provide a cellulose material-to-wood segment interface that withstands high shear stresses. The reinforcement panel is comprised of a plurality of reinforcement fibers that are preferably arranged parallel to one another and aligned with the longitudinal direction of the panel, and accordingly the wood structure. The fibers are maintained in position by a resin encasement that completely encloses the fibers. A cellulose surface material is impregnated with a polyester resin and adhesively connected to a first side of the panel. The first side of the panel is adhesively affixed to the wood structure at an area of high stress such that the surface material is sandwiched between the resin encasement of the panel and the wood structure. Thus, the panel provides improved adhesion.

The functionalities and amounts of components a) and b) are such that the molecular weight between crosslinks is from about 7,000 to about 16,000 and the equivalent ratio of isocyanate groups to isocyanate-reactive groups is from about 80:100 to about 120:100 and the urethane group content is from about 1 to about 8%. It is preferred that at least one of components a) and b) have a functionality of greater than about 2.2.

Abstract: This invention relates to improved polymer-pressure sensitive adhesive combinations, particularly in the form of laminates, and methods of producing same. This invention improves the bond strength of the pressure sensitive adhesive to the polymer layer by priming the polymer surface with a curable urethane primer before applying the pressure sensitive adhesive to the polymer surface. If the polymer surface is not "active" to the curable urethane primer, the polymer surface is first activated with a silicon-containing treating agent. The laminates of this invention have superior bond strength, especially longterm bond strength. Of particular interest are the embodiments of this invention wherein the polymer is a silicone foam and the pressure sensitive adhesive is either acrylic or silicone adhesive.

Abstract: A sheet for protecting paint films of automobiles for adhering to the incompletely cured paint films of automobiles comprising two pack urethane paint, the sheet comprising a support and a pressure-sensitive adhesive layer formed thereon, wherein the sheet has a Young's modulus E of at least 75 N/mm.sup.2 and a coefficient of flexural stress k represented by the formula k=Eh.sup.3 wherein h is a thickness of the support, of 0.035 or less. The protective sheet can uniformly protect the paint films and easily be peeled and removed therefrom without causing environmental problems and adhesive remaining of the pressure-sensitive adhesive layer. Even when the sheet is adhered to incompletely cured paint films of automobiles and they are allowed to stand for a long period of time under an outside high temperature in summer, the sheet does not cause the deformation of the paint film and the microdeformations by the deformation of the paint film at the edge portion of the pressure-sensitive adhesive layer.

Abstract: A device comprising a carrier tape with compartments and a cover tape for sealing items in the compartments includes a cover tape having a base film layer, a striped adhesive layer formed on the first surface of the base film to adhere the cover tape to the carrier tape, and an antistatic layer formed on the adhesive layer and base film layer to provide antistatic coating on substantially the entire width of the surface of the base film. A primer layer containing an antistatic agent may be placed on the base film layer as an alternative to an antistatic layer.

Abstract: New fiber-reinforced composite materials of improved moldability and methods for making them, in which an initial material comprising long length ("continuous filament") reinforcement set in a matrix material is treated to enable these filaments to be severed in situ into fibers of smaller length while maintaining a control over the length and location of these resulting shortened fibers while preserving the orientation desired to give strength to the materials. The severance is preferably achieved using radiant energy from a laser or the like, and most conveniently by using a laser to make a series or pattern of perforations (usually 0.5 mm or less in diameter) so that the reinforcing filaments are attacked but the surrounding matrix material is not appreciably affected or weakened. The treated materials can be used to fabricate larger products or articles of wide variety, by further processing, especially molding or thermo-forming.

Abstract: A shaped sanitary napkin. The sanitary napkin of this invention has an absorbent means, such as an absorbent core, and two flaps extending outwardly from the absorbent means. Each flap is associated with the absorbent means along a nonlinear line of juncture and each has two axes of flexibility. In use, the absorbent means is secured in the crotch of a panty and the flaps are secured about the elastic edges of the panty so that, when the panty is worn, the absorbent means is held adjacent the body while the flaps form a wall at each side of the absorbent means and seals against the body. Both the walls and the seals serve to prevent soiling of the body and clothing by menstrual fluid.

Abstract: A side entry heat recoverable article (2) pre-formed to enable a wire bundle (4) to be easily positioned and maintained within the article prior to recovery of the article. The wire bundle snaps into an enlarged section (6) between tab portions (10, 12). An adhesive (24) is disposed on the interior surface of the article for securing the tab portions together and for sealing the wire bundle. Upon recovery of the article, the wire bundle is thereby sealed within the heat recoverable article. A heat recoverable tube (2'), including adhesive, undergoes a post processing step to form the slit sleeve (2) that can be easily handled and installed.

Abstract: An interposition layer (12) is formed on the outside surface of a part (10) made of thermostructural composite material containing carbon, and a metal case is formed by casting molten metal (22) around the part provided with its interposition layer. The interposition layer has closed porosity and it is proof against the metal of the case, such that shrinkage of the metal during cooling is absorbed by compacting or collapsing the porosity of the interposition layer, thereby preserving the integrity of the metal case, and the interposition layer constitutes a diffusion barrier preventing eutetics forming by contact between the metal of the case and the composite material.

Abstract: A removable adhesive tape comprising a highly extensible and substantially inelastic backing and a layer of pressure-sensitive adhesive. The backing has a high tensile strength, has a lengthwise elongation at break of at least about 150% with less than about 50% elastic recovery after stretching. The adhesive can be a normally tacky and pressure-sensitive adhesive and is coated on at least one surface of the film backing. The adhesive is preferably highly extensible, does not separate from the backing during stretching, and has higher cohesion than adhesion to any suitable substrate. After being applied to a substrate, the adhesive tape of the present invention becomes firmly bonded, but can be easily removed without damaging the substrate by simply stretching it in a direction substantially parallel, i.e., less than about 35.degree., to the surface of the substrate.
